I have started sorting through and organizing all my old files from the past 3 years. This could take as long as 1 to 2 months, so I won’t be blogging for a while.

January 22nd, 2010 by lost_wandererUpdate on Not Using Soap or Shampoo
December 31st, 2009 by lost_wandererFollowing up on an earlier post, (You Don’t Need to Shampoo Your Hair (Or use Soap) – Lost Wanderer) Boing Boing has just blogged (Body washing with water alone) about a report by Free the Animal (Paleo I Don’t Care: I Like No Soap; No Shampoo) in which he talks about his very good experience with going soap and shampoo free for the last six months. Both the Boing Boing and Free the Animal posts are followed up with numerous comments by readers.
Radon Gas
December 16th, 2009 by lost_wandererRadon is an invisible, odorless, radioactive gas that is created when naturally occurring uranium in rock and soil decays. People breathe this gas in and while it is in a person’s lungs it decays into radioactive particles, which are trapped there while they, in turn, undergo further decay. It accounts for about 56% of all the radiation the typical person receives in a year, and can eventually lead to lung cancer. (1) (Your radiation exposure - Radiological Protection Institute of Ireland)
Even though radon has always been with us, until homes and buildings became well insulated it didn’t present much of a problem since the average concentration of radon in outside air is a low 0.4 picocuries per liter (pCi/L). (2) The real concern is that radon can accumulate to much higher concentrations in indoor air because over the years construction standards have improved resulting in better sealed homes. In such situations radon can seep into buildings through cracks in their foundations, through well water, or come in around water or sewer pipes, and increase in concentration. (3) The result is that the EPA estimates that the average indoor level of radon is 1.3 pCi/L and at this level over a lifespan it will cause between 3 and 13 lung cancer deaths per 1,000 people. (The Health Risk of Radon Gas – VSI Environmental) A level of 1 pCi/L is the risk equivalent of 20 chest x-rays per year, and a level of 4pCi/L is the risk equivalent of 200 chest x-rays per year. (Radon Myths and Facts – Radon Doctor) It’s estimated that radon causes about 21,000 additional lung-cancer deaths every year in the United States. By comparison drunk driving kills about 17,400 people a year, falls in the home 6,000 a year, and home fires about 2,800 a year.
Given this situation standards were necessary, and the EPA eventually determined that a reasonable action level was 4 pCi/L. Even at this moderate concentration it’s estimated that one in fifteen homes are above it, and over a lifespan there will be between an additional 13 and 50 people in 1,000 who will die from lung cancer. For those who smoke the issue is even more pressing since it is known that smoking synergistically interacts with radon, multiplying the risk of lung cancer for any given level of exposure. Because of these facts the U.S. Congress has set a goal that indoor radon levels should eventually be reduced to the same as outdoor levels, but the problem is that this can’t be done with the current technology and available resources. For now people can generally afford to reduce radon to around 2 pCi/L.
Radon levels do vary greatly within buildings, with the highest concentrations in the lowest areas, and above the first floor the problem largely disappears in many homes. To determine the level of radon in a building there are do-it-yourself kits as well as professional testing. The kits are of two types, short term (less than 90 days) and long term (greater than 90 days). The advantage of the short term kits is that they provide a quick understanding of the situation, while the long term ones give a better understanding of the average indoor radon level throughout the year. This is important since the concentration of indoor radon can vary greatly depending on such factors as how often windows are left open. Frequently both methods are used since they are both fairly inexpensive. However when selling a home these methods often aren’t sufficient and professional testing is necessary since independent documentation is frequently required.
If the levels are above 4pCi/L, there are several common methods available to address the problem. The simplest approach is to seal the cracks in the building’s foundations. Then the next step is a vent pipe system, which involves using a pipe and fan to suck radon from beneath the building’s foundation and vent it to the outside air. These methods aren’t excessively costly, and typically run about $1,200 for repairing a home if a contractor is used.
(1) Although the literature is generally of the opinion that lung cancer is the only health risk from radon, some people speculate that radon might also be a risk factor for Alzheimer’s. (Alzheimer’s – Lost Wanderer)
(2) It should be noted that, since the risk from radon is continuous, no level is safe. Even at the 0.4 level over a lifetime such exposure will lead to about 1-3 people in 1,000 to die from lung cancer.
(3) Radon levels in homes can get very high. In 1984 Stanley Watras was a construction engineer working on the Limerick Nuclear Power Generating Station in Pottstown, Pa. Before the plant had gone into operation he found himself setting off the radiation alarms when he was entering the plant. The problem was eventually traced to high levels of radon in his home, which had 4,400 pCi/L in the cellar, 3,200 pCi/L in the living room, and about 1,800 pCi/L in the bedrooms. (Radon – A Short History) This level presented an equivalent risk to him of smoking 135 packs of cigarettes a day, or 49,275 packs a year. (Stanley Watras – Wikipedia)

We Need Our Symbiotes II
December 15th, 2009 by lost_wandererFor a short follow-up to my prior blog post, (We Need Our Symbiotes – Lost Wanderer) Gut Buddies reports the following:
- The Bifidobaterium lactis strain may be partly responsible for breast-fed infant’s enhanced immune systems.
- Bifidobacterium infantis may reduce symptoms associated with inflammatory bowel disease and irritable bowel syndrome (bloating, cramps, gas, diarrhea).
- Lactobacillus bulgaricus and Streptococcus thermophilus are used in yogurt and help decrease lactose intolerance and may prevent diarrhea. Be sure the label on the yogurt says it contains live and active cultures.
- Lactobacillus rhamnosus GG (LGG) and Saccharomyces boulardii may help treat diarrhea associated with antibiotic treatment. Antibiotics sometimes destroy healthy bacteria while trying to kill unhealthy bacteria and sometimes diarrhea will result.
- Lactobacillus acidophilus may help decrease yeast infections.
- Lactobacillus casei may help reduce the incidence of cancer, specifically bladder cancer.
We Need Our Symbiotes
December 14th, 2009 by lost_wandererMy next post will be on avoiding food poisoning, but before I post on that issue I need to point out that there obviously exists a balance between living in disease causing filth and being obsessively hygienic. A lot of research suggests that we need various probiotics in order to be healthy, and that a large number of health problems occur because we have cleaned up our environment so thoroughly that we don’t have the necessary symbiotes in our bodies any more.
The hygiene hypothesis seems to be gradually being refined into what has been called the Old Friends Hypothesis. The shift is from one of believing that we benefit from infections with various organisms in general sort of way, to saying that bad organisms are bad for us, and good organisms (symbiotes) are good for us. So, obviously we should try to avoid the bad ones and seek out the good ones. Here are two previous blog posts of mine that touch on this issue The Umami Hypothesis – Lost Wanderer and Apitherapy & Biotherapy – Lost Wanderer.
Here is a general survey of some of this material by Gut Buddies: ‘Friendly’ bacteria: side-lined healers - Gut Buddies (Some of the friendly bacteria (and products) referred to by Gut Buddies in this post are: segmented filamentous bacterium, Lactobacillus acidophilus and Bifidobacterium animalis, Bifidobacterium infantis 35624, Puritan’s Pride, Lactobacillus reuteri, B. infantis 35624, Lactobacillus F19, L. acidophilus NCFB 1748 and B. lactis Bb12, Advanced Oral Hygiene with S. salivarius and B. coagulans, PerioBalance with Lactobacillus reuteri Prodentis, Halofuginone, and Bacillus polyfermenticus).
Helminths (hookworms and whipworms, etc.) have been apparently very effective in helping with numerous allergic and autoimmune conditions, including allergies, asthma, autism, Crohn’s Disease, Eczema, Irritable Bowel Syndrome, Multiple Sclerosis, Psoriasis, Sjögren’s Syndrome, and Ulcerative Colitis.

Recently, Matt Metzgar has been posting a lot on the topics of probiotics (1) and prebiotics. Matt began by pointing out the site Paleobiotics, which discusses how the ancient diet influenced people’s gut flora. The diets of hunter gatherers would have had a lot of indigestible fibers in them, which were instead consumed by our gut bacteria. Since we no long eat this sort of diet we harbor somewhat different colonies of bacteria, to the likely detriment of our health. Matt points out that in one study (Can vegetables help you resist infection?) that men who took prebiotics massively increased their good gut bacteria, but the group only taking a probiotic didn’t benefit very much. (See also: Eat Bugs. Not Too Much. Mainly With Plants via Prebiotics versus Probiotics - Matt Metzgar)
Conditions that Matt talks about that might be influenced by the types of bacteria we harbor include:
Allergies (The role of Probiotics in allergic diseases, Maternal breast-milk and intestinal bifidobacteria guide the compositional development of the Bifidobacterium microbiota in infants at risk of allergic disease, (bifidobacteria) Babies, Bacteria and Breast Milk: Genome Sequence Reveals Evolutionary Alliance (Bifidobacterium longum supsp. infantis) via Balancing Bacteria - Matt Metzgar and Babies and Bacteria – Matt Metzgar)

Safe and Green Cleaning
December 12th, 2009 by lost_wandererIn one of my earlier blog posts I discussed the miracle cleaner electrolyzed water, but for now we will have to get by with other products. Matt Metzgar has discussed using Green Works and Ecover products. (Green Works – Matt Metzgar and Going Green – Matt Metzgar) (Although, for a critical review of Green Works products you can read, “The Four Biggest Enviro-Scams: Green claims that make us see red” By Amy Tennery, who recommends Seventh Generation products as superior. (But be sure to also read the rebuttal to this.)) Another such product line is EnviroRite’s. And online, Greenhome.com sells a number of such products.
For those who want to go a step further, and live as safe and green as possible, you can make your own products. I won’t try to reproduce the vast lists of specific formulas people recommend for doing home chores, but only try to hit a few of the highlights. If you wish to pursue this, the links provided below should more than get you going. (Also, for a whimsical perspective on replacing products with substitutes – which aren’t necessarily green – you can take a look at Joey Green’s Wacky’s Uses for Brand Name Products site.)
There are a few ingredients common to many of the recommendations people make. (From Non-Toxic Home Cleaning - Eartheasy):
Baking Soda – cleans, deodorizes, softens water, scours.
Soap – will clean most things. (unscented, phosphate free, and doesn’t contain petroleum distillates)
Lemon (juice) – a strong acid that is effective against most bacteria.
White Vinegar – cuts grease, removes mildew, odors, some stains and wax build-up.
Washing Soda – is sodium carbonate decahydrate. It will cut grease, remove stains, soften water, clean walls, tiles, sinks and tubs. Do not use on aluminum.
Ethanol Alcohol – is an excellent disinfectant.
Corn Starch – can be used to clean windows, polish furniture, and shampoo carpets and rugs.
Hydrogen Peroxide - used as a disinfectant.
You can find suggestions for just about every conceivable purpose: air fresheners and deodorizers, fabric softeners, furniture polish, stain removers, pesticides (ants, fleas, flies, mice, mites, mosquitoes, moths, roaches, wasps, etc. ), windshield washer fluid, shoe polish, rust removers, disinfectants, cleaners for glass, your hands, the oven, vinyl, wood, drains, mildew, toilets, paintbrushes, floors, tub and tile, aluminum, copper, brass, silver, porcelain, etc.
On a related issue, there are sites online that focus on cosmetics safety. The Campaign for Safe Cosmetics. Here is an article that discusses this issue: Safe Cosmetics by Christina Hartje-Dunn,

Lead Poisoning
December 11th, 2009 by lost_wandererLead has no known function in the human body. It’s an insidious toxin with a very broad range of symptoms, and even people who appear healthy can have dangerous levels of it in their blood. The problem of lead contamination is entirely a result of civilization, since levels in pre-industrial people (in the range of 0.01 micrograms/deciliter (mcg/dl)) were around 100 to 1,000 times lower than blood levels typically found in people today. (Lead Toxicity, A Review of the Literature. Part I: Exposure, Evaluation, and Treatment Lyn Patrick, ND)
One of the major players in this disaster was the Ethyl Corporation. In its pursuit of profits it criminally exposed workers to lead in its factories, and lied about it while they were dying. Its lead-based-no-nock-gasoline-additive eventually put about seven million tons of lead out through the tailpipes of cars into the atmosphere. (1) (The Ethyl-Poisoned Earth by Alan Bellows)
The main cause of lead’s toxicity is its ability to interfere with many enzymes by binding to their sulfhydryl groups. Short term measurable effects of lead poisoning begin at 25 mcg/dl. Obvious symptoms begin to occur at levels above 40mcg/dl in adults, and above 60 mcg/dl in children.
The list of potential health problems related to lead is a very long one: Lead can damage hearing, vision, muscle coordination, the blood, kidneys, heart, and reproductive system. Symptoms can include abdominal pain, anemia, loss of appetite, constipation, delayed growth, depression, diarrhea, fatigue, headaches, irritability, decreased libido, memory loss, muscle pain, nausea, personality changes, problems with sleep, an unusual taste in the mouth, weakness, tingling in the extremities, vomiting, and weight loss. In one recent study those people with blood lead levels in the top 20% (over 2.11 mcg/dl) of the subjects had 2.3 times the odds of suffering from a major depressive disorder, and almost 5 times to odds of having a panic disorder as those in the lowest 20% (under 0.7 mcg/dl). (The average blood lead level of the group was 1.61 mcg/dl.) (Young Adults’ Blood Lead Levels Linked to Depression, Panic Disorder)
Exposure to even low levels might cause irreversible learning difficulties and mental retardation in children. One study found that the IQ scores of children dropped about 7 points across the sample as children’s blood lead levels varied from 1 mcg/dl to 10 mcg/dl. (2) (Very Low Lead Levels Linked With IQ Deficits)
The current consensus is that there is no safe level of lead exposure. Lead accumulates in the blood, soft tissues and bone; and its half-life is weeks in blood, months in soft tissues, and years in bone.
In the past lead was used commonly in house paint, as an additive to gasoline, and as a pesticide. One piece of good news in all this is that the Clean Air Act has helped reduce air emissions of lead nearly 90 percent during the last 20 years.
If you have a problem with lead contamination there are a number of things you can do to deal with it:
Make sure your child’s blood is tested for lead before age 2, and regularly to age 6, if there is the possibility of lead in the child’s environment. The major treatments are removal of the source of lead and possibly chelation therapy (administration of agents that bind lead so it can be excreted). (Chelation therapy – Wikipedia)
Around the home anything that has paint or a finish made before 1978 in the U.S. could be a source of lead. (It was banned in France and many other countries before 1920.) So you shouldn’t use cribs, bassinets, highchairs, painted toys, or toy chests made before that date. Lead paint is still sometimes found in toys and toy jewelry made today, so you should keep up on toy recalls by checking the lead recall lists. (Toy Hazard Recalls – CPSC) Unfortunately, 75% of the nation’s housing has lead paint. Broken down by time period, 90% of pre-1940 buildings have it, 80% of pre-1960 ones have it, and 62% of pre-1978 buildings have it.
Keep children away from paint chips (which they might eat) by closing and locking doors. You should create barriers between living and play areas, and the sources of lead. Apply temporary barriers such as contact paper or duct tape to cover lead sources.
Lead contaminated dust can be created by the friction of opening windows and doors, it might be blown in - coming from distant contaminated soils, or it can be generated during home renovation on a pre-1978 house. Lead dust is invisible and will pass through most masks and filters, so, if you have to sand or strip old paint that may contain lead, be sure to use a high quality mask to prevent inhalation of lead particles. Regularly wash children’s hands, pacifiers, toys, and any other items that might go in the mouth. Feed children nutritious low-fat meals high in calcium and iron, since this will reduce the amount of lead absorbed into the body. Wet-mop and wipe floors, window components, and other horizontal surfaces (counters, tables or floors) frequently. If possible, windows should be kept shut to prevent abrasion of painted surfaces, or only opened from the top sash. Don’t vacuum with a regular vacuum because it just lets lead dust fly around, but instead use a vacuum cleaner that utilizes a HEPA (High-Efficiency Particulate Air) filter. Pregnant women and children shouldn’t be present during a pre-1978 house renovation.
Lead was often in exterior oil-based paint prior to 1950, and as it ages it often contaminates soil about a house where children play. Stop children from playing in bare soil and close to the sides of the house. Instead, provide them with a sandbox more than 3 feet away from it. (If your do have a sandbox, parents should cover the box when it’s not in use to prevent cats from using it as a litter box.) Plant grass on areas of bare soil, or cover the soil with mulch or wood chips. Take off your shoes when you go inside, and, if you walk barefoot outside, wash your feet when you go indoors. Also, give your pet’s feet, legs, and undersides a rubdown with a towel after taking them outdoors.
Lead solder can contaminate house pipes, so, unless you know your pipes are uncontaminated, you should only use cold water from the tap for drinking or cooking. Also, if water sits in a pipe for several hours flush it from the tap for two minutes before drinking. You can also use a water filter to reduce the lead in the water you cook and drink with. For example, a simple Brita water filter will remove around 9o% of the lead found in tap water.
Replace inexpensive, horizontal, plastic blinds that have been made in Asia or Mexico, since these types of blinds often contain lead. Pregnant women and children should not be exposed to burning candles that could contain lead in their wicks. Don’t drink out of crystal glass. Soft vinyl lunch boxes can have dangerous levels of lead. Avoid using any personal care products that contain significant amounts of lead.
Hobbies that often involve working with lead are making stained glass windows, working with pewter and other collectible figurines, the glazing and firing of pottery and ceramics, making lead weights, reloading and making ammunition, making lead shot, target practice, making lead fishing weights or lures, refinishing furniture, and remolding. You should never sand, burn, or scrape paint unless you either know it doesn’t contain lead, or take the proper precautions. You should shower and change clothes after finishing a task that involves working with lead-based products.
Sites where lead might be a problem are hazardous waste sites, an area where cars are abandoned or repaired, ballast on a ship, a heavily traveled major highway or roadway, and an older house with peeling exterior paint. Also artificial turf playing fields have recently been found to produce a potentially hazardous amount of lead dust.
Other sources of lead are kohl (a South Asian cosmetic), sindoor (a cosmetic used by traditional Hindu and Sikh married women), herbal remedies (Ayurvedic preparations (Ghasard, Bala Goli, and Kandu), surma, and those of Chinese origin), and folk remedies (azarcon (also called Maria Luisa, Liga, Alarzon, Alkohl, Greta, Coral and Rueda), farouk, bint al zahab, and pay-loo-ah). Additional sources are solder which was used in the past to seal cans of food, ceramic glazes, lead curtain weights, lead bullets from hunted animals, bullets lodged in a person’s joints (since they deteriorate over time), imported candies that contain tamarind or chili, contaminated pottery, containers, cookware, or tableware. Older Christmas tree ornaments might be decorated with lead paint, and lead is in some tree light wires. Old newspapers, paper bags, magazines, and comic books could have been made with lead based inks. You should never burn treated lumber, since there will be heavy metals in the smoke. Industrial facilities, urban runoff, and atmospheric deposition are all sources of lead in the aquatic environment. Even your keys can often contain small amounts of lead.
Types of work that is typically associated with the risk of lead contamination include house construction and repair, shipbuilding, painting (especially marine related painting), iron processing, brass or copper foundry valve and pipe fitting, bronze work, welding, resurfacing, bridge, tunnel, and elevated highway construction; the demolition of bridges, towers, and other steel structures; lead battery manufacturing and recycling, radiator manufacturing and repair, scrap metal recycling, the electronics industry, the manufacture of some plastics, automotive repair, fishing weight production, leaded glass manufacturing, lead ore production, milling, and smelting; and municipal solid waste incinerators.
If your workplace poses a risk of lead contamination there are a number of safety precautions you should take: You should work with your employer to reduce lead and lead exposure in the workplace, perhaps by providing special ventilation equipment and/or fitted respirators. Wash your hands and face before eating, drinking, or smoking. Eat, drink, and smoke only in areas free of lead dust and fumes. Wet clean and HEPA vacuum lead-contaminated dust. Use separate work clothes and shoes while at work, and keep your street clothes in a clean place. Shower at work before going home, and launder your work clothes at work. If you take your work clothes home, wash and dry them separately.

For a home test, see: http://leadtestkit.com/kits1.html
You can also talk to your state or local health department about testing paint and dust from your home for lead.
To permanently remove lead hazards, you have to hire a lead “abatement” contractor. Call your local paint stores to find out if the contractor you’re considering has a good history with the store. Find a contractor who has been in business for several years, and can offer references. The longer they’ve been in business, the more they will likely know about lead. Find a contractor with whom you feel comfortable, and who can answer your questions and explain their work.
(1) Only one of the many consequences of this might have been a nationwide crime wave. A number of recent studies have shown a strong correlation between atmospheric lead levels and crime rates. The sharp decline in US crime rates, which began in the early 1990s, correlates perfectly with the reduction of leaded gasoline in the early 1970s. Other countries have seen similar declines, also delayed by twenty years. (The Ethyl-Poisoned Earth by Alan Bellows)
(2) Throughout this entire discussion there exists the common problem of inferring causation from correlation. Since direct experiments with humans would be unethical, many results require an assumption that lead is actually the cause of a health problem. At higher levels of contamination this assumption is unproblematic, but at lower levels this can be a source of uncertainty. Looking at the national lead standards for blood toxicity through the years, in the space of about 50 years, they have changed six-fold from 60 mcg/dl to 10mcg/dl. One reason to be skeptical of a 7 point IQ drop because of such low lead levels is that this suggests that people who grew up in the 1950’s and 1960’s would have had greatly reduced IQ’s, and this doesn’t seem to have been the case.
In 1960, 60 mcg/dl
In 1970, 40 mcg/dl
In 1975, 35 mcg/dl
In 1985, 25 mcg/dl
In 1991, 10 mcg/dl
It is certainly possible that raising a child’s blood lead level from 1 mcg/dl to 10 mcg/dl directly causes an average 7 point drop in IQ. The problem here is that there are potentially hundreds of confounding variables that could be creating the observed correlation. It’s possible that children with lower IQ’s have a greater tendency to chew on paint chips, be less well-nourished, or attend poorer schools. Also, parents with lower IQ’s might have a greater likelihood of living in lower quality housing and in more contaminated neighborhoods, be less aware of the dangers of lead poisoning, or be less competent when taking precautions, etc. So, the connection between lead at low levels and IQ could be one of children inheriting genes from relatively lower IQ parents, which predispose them to also have lower IQ’s.
In short, while it is entirely reasonable to take no unnecessary chances with lead poisoning (personally I would prefer my blood level to be literally zero), it’s only careful to remember that researchers haven’t actually established an airtight connection between the low blood lead levels and the observed health effects they are currently concerned about.

Preventing Home Poisonings
December 8th, 2009 by lost_wandererIn an earlier post I blogged about carbon monoxide (CO) poisoning. (Carbon Monoxide – Lost Wanderer) But, there are obviously many other ways you can poison yourself:
According to the CDC, poisonings killed 32,691 people in the United States in 2005. About 72% of these were unintentional (23,618), 10% undetermined (3,240), 18% suicides (5,744), and 0.3% homicides (89). To understand where the bulk of this risk is coming from it’s important to know that 95% of the unintentional poisoning related deaths were caused by drugs. The most common drugs involved, in descending order, were opioid pain medications, cocaine, and heroin. Benzodiazepines, sedatives, hypnotics, and antidepressants were also commonly involved. (Poisoning in the United States: Fact Sheet – CDC)
If we look at poisonings of children under age 6, in 2001, drugs accounted for 42% of poisonings, and non-drugs accounted for 58% of the total. 90% of these events occurred at home. (Pediatric Poisoning by John P. Lamb)
Drug poisonings in this age group involved analgesics (19%), topicals (19%), cold/cough (15%), vitamins (10%), antimicrobials (8%), GI preps (9%), hormones (7%), antihistamines (7%), minerals/Lytes (3%), and antidepressants (3%). Among analgesics the percentages were ibuprofen (40%), acetaminophen (31%), others (11%), combination (10%), aspirin (5%), and opiates (3%).
Non-drug poisonings in children under 6 involved cosmetics (26%), cleaners (22%), foreign bodies (15%), plants (13%), pens/inks (6%), pesticides (5%), hydrocarbons (4%), foods (3%), rodenticides (3%), and alcohols (3%). The pesticides involved were insecticides (51%), rodenticides (22%), repellents (14%), herbicides (10%), fungicides (2%), and fumigants (1%). Insecticide exposures in 2002 were from the following sources: Pyrethrin (37%), organophosphate (22%), others (16%), borates (8%), unknown (8%), Carbamate (6%), combinations (5%), Chlorinated HC (3%), Arsenic (1%), and Metaldehyde (0%). Herbicide exposure in 2002 was 14,021, and was from the following sources: other (43%), Glyphosate (32%), Chlorophenoxy (15%).
The effects of pesticide exposure broke down in the following way: no effect 21,844 (55%), minor effect 14,563 (37%), moderate effect 2,661 (7%), major effect 274 (0.7%), death 18 (0.05%).
The routes of exposure were oral (76%), dermal (8%), inhalation (6%), ocular (5%), bite/sting (4%), and other (1%).
The common characteristics across poisoning situations for children were availability, attractiveness, and taste. This isn’t surprising since 47% of households with children under 5 living in them had pesticides stored in an unlocked cabinet less than 4 feet high. 75% of households without children under 5 also had pesticides stored unsafely, which might not seem to be much of a problem, except for the fact that 13% of pesticide poisonings occurred in a home other than the child’s own.
Hazardous substances fall into a number of categories: Reactive ones are unstable and produce dangerous byproducts. Corrosives are acidic or alkaline, and will eat away at substances. Ignitables can catch fire. Toxic substances are by definition poisons.
In your garage or shed you might have antifreeze (which tastes sweet to dogs and cats), other automotive fluids, cleaning fluids, hand cleaner, car soaps, rust remover, lamp oil, polish and wax, fertilizer, weed killer, gasoline and kerosene, lighter fluid, lime or lye, mothballs, paint, paint thinner and stripper (paint strippers are among the most dangerous products in your home), pesticides (such as rat and other rodent poisons), insecticides (such as roach sprays and ant baits), insect repellents, turpentine, pool chemicals, charcoal lighter, windshield washer fluid, and anti-freeze .
In your kitchen you might have ammonia, bug sprays and traps, floor wax, cleansers (including floor, carpet, oven cleaner, and window), disinfectants, drain openers, medicines (both prescription and over-the-counter), glues, polish (for furniture, metals or glass), soaps and detergents. (Note: You should be very careful about mixing cleaning products. For instance, if you mix bleach with toilet bowl cleaners (or ammonia) this combination will form very deadly chlorine gas.)
In your bedroom you might have cosmetics, perfumes, colognes, cough medicine, prescription drugs, and sleeping aids.
In your bathroom you might have aftershave lotion, baby oil, toothpaste, alcohol, hydrogen peroxide, bath oil, cleansers (including floor, window, toilet bowl, and tub/tile cleaners), disinfectants, deodorizers and sanitizers, products used to kill mold or mildew, drain openers, hair removers, hair colors and perm solutions, nail products, personal hygiene products, mouthwash, ointments, flea and tick shampoos, powders and dips for pets, and shampoo.
In your laundry room you might have laundry detergents, softeners, bleach, cleaning fluids, soaps, stain removers, and spray starch.
One special case is that of your art supplies. Lead glazes can cause lead poisoning. Rubber cements can cause nerve damage. Acrylic paints can contain formaldehyde. Oil paints, or anything that requires solvents, can be toxic. Darkroom chemicals can be hazardous. Dust from sanding can trigger allergic reactions. Copper salt dust can be toxic. Turpentine can strip oil off skin, making it vulnerable. “Zinc shakes” and “bronze fever” have occurred.
Often the dose does make the poison, so be aware of the extent of your exposure and try to space it out. Temperature can also make a difference, since in warm temperatures liquids evaporate more quickly. (Using Art Materials Safely) (Art and Hobby Materials) (Health Hazards Manual for Artists by Michael McCann)
For children you should make sure everything is labeled non-toxic. Safe materials for children include crayons, colored pencils, water colors, finger paints, many modeling materials, some inks, and some glues. (ACTS : Arts, Crafts & Theatre Safety) (Kids Art)
Other hazards you might have in your home are alcoholic beverages, vitamins, supplements, diet pills, hair sprays, colognes, nail polish and remover, furniture polish, cigarettes, nicotine patches, folk remedies and herbal preparations, ammunition, and batteries (including button cell batteries like those in watches).
One basic way of minimizing the danger from hazardous substances, etc. is by limiting your use of them and educating yourself about safer alternatives. Most household cleaners can be replaced by five things: plain soap, borax, baking soda, vinegar, and ammonia. Instead of cough medicine you can mix honey and lemon juice with hot water. Instead of iodine you can use soap and water. (Home Safe Home by Deborah Lynn Dadd, Nontoxic, Natural & Earthwise by Deborah Lynn Dadd, and Green Seal) The general rule is to use the least powerful chemical necessary to do the job. The warnings run from “DANGER, DANGER – POISON,” to “WARNING,” to “CAUTION.” Get the product designed to address your specific problem, and, unless you are an expert, only buy pesticides labeled for general use.
For the dangerous things that you do decide to keep in your house (the following advice includes medicines) store all hazardous substances separately in a locked and high cabinet protected from heat and cold. Return a container to the cabinet immediately after removing the amount needed. (You need to consider how best to secure your cosmetics, given the number of poisonings they cause.) For a second layer of defense put child safety caps on all of the containers you can. But don’t rely on packaging to protect your kids, since child-resistant packaging does not mean childproof packaging. Keep children and pets away from a work area, and remove toys. Obviously, a woman who is pregnant should stay away when hazardous chemicals are being used.
Always keep dangerous substances in their original containers, since their labels provide valuable information in the event of an accident, and substituting other containers invites deadly confusion. (You should apply transparent tape over the labels to keep them legible.) You should read these labels (and any relevant safety data sheets that are available) and know the details about what you have. (1) Follow their advice regarding the recommended safety precautions and product restrictions, and contact the manufacturer if you have any questions. For example, use neoprene gloves, eye goggles, long sleeves, long pants, socks, shoes, proper cross-ventilation, and masks if the label says to.
Make sure your equipment is in good working condition. Open containers carefully with a rag around the cap. Proper ventilation requires by definition a large turnover of air. Turn on a fan (unless a substance is highly flammable) and open several windows when using chemical products such as household cleaners. Don’t use power tools with flammable materials. Mix insect sprays outdoors away from areas used by people and pets, and stay upwind. Basements can allow fumes to collect near the floor. Don’t spray when it’s windy. Follow the waiting times before allowing anyone into the area treated. You should never keep gasoline in your home, but if you do use a specifically designed container for gasoline. Some paint strippers will produce toxic gas if used in direct sunlight. Only use the amount of product recommended for the application, clean up any spills as soon as they happen, and wash off thoroughly after any contact with a hazardous substance. Don’t apply a pesticide more often than recommended. Be sure you know how close to harvest you can apply a product. If you are working with poisons don’t wear leather belts or shoes. Don’t smoke, drink, or eat when handling these materials. Re-close containers if interrupted (e.g. phone call or doorbell) during an application or dosing. Remember that most poisonings happen when a product is in use. Often something is going on which distracts people, such as someone is sick, there has been a death in the family, or it is mealtime.
Wash all sprayed fruits and vegetables. One method is to put them in vinegar and water for a few minutes, and rinse again with water. You should wash your clothes three times separately after exposure to strong pesticides. Triple rinse tools, equipment, or empty containers. Puncture empty containers so they can’t be reused, and dispose of them according to directions.
Only buy and mix what you need, then use it up. In other words, don’t buy in bulk. If you store hazardous substances for long periods of time they can react with their containers, which can then leak. Another problem is that their labels can become worn.
You should properly dispose of expired materials. Do not burn them. Also, don’t burn or reuse their containers. Don’t burn plywood or lumber that has been treated with preservatives, the resulting fumes can be thick with heavy metals.
Your local public health or hazardous-waste organization is often the best place to find information about how to dispose of a product. Some things such are motor oil, or batteries, can be recycled. Hazardous waste often needs to be put into special landfills.
You need to know the names of your medications and supplements, both prescription and over-the-counter. When you take or give medicine put your glasses on, turn on the lights, and read the label every time. Always check for the proper dose, and be sure you are giving the right medication to the right person. Never take another person’s medicine. Take medicine at the correct time of day, and keep track of when you took it by writing it down if necessary. Know and don’t confuse the abbreviations for tablespoon (Tbsp) and teaspoon (tsp). Avoid making conversions. If the label says two teaspoons, and you’re using a dosing cup with ounces only, get another measuring device. If the medicine came with a measuring device use only that device. Know how much medication you have, so you can tell if any is missing by regularly doing a count, and keeping a line marked on bottles.
Never guess on the amount of medicine that should be given to someone. For example, kids aren’t just small adults; half an adult amount may be more than your child needs, or not enough to help. Always follow the age limit recommendations. Twice the dose obviously isn’t appropriate just because your child seems twice as sick as last time.
It can be confusing when there are multiple caregivers giving medications to someone. Be sure to communicate to each other every dose you give, and also write down each dose given in a log.
Medications can interact with each other. If someone is already taking one medicine, check with your doctor before adding any other meds to be sure they are compatible. If multiple doctors are prescribing a variety of medications, be sure to communicate with each doctor and your pharmacist so they can check for drug interactions. Some medicines will interact with certain foods, some need to be taken with food, some without.
Never leave vitamin bottles, aspirin bottles, or other medications on kitchen tables, countertops, bedside tables, or dresser tops. Children will imitate you, so ideally take your medicines where children can’t watch, and never call medicine candy. Teach children to ask before eating or drinking anything. Talk about prescription drugs, and stress that they are only safe for the person who receives the prescription from the doctor. (For advice on how to talk to your child/teen go to www.drugfree.org) Something as seemingly harmless as pain-relieving skin creams will often contain benzocaine, dibucaine or lidocaine. A child who swallows just a small amount of these can have seizures and might even die.
Throw away expired medications in the garbage. Don’t put them down the sink or toilet because they can contaminate the water supply. For privacy sake remove the labels. Keep children and pets away from the garbage. Crush old pills and mix them with sand, coffee grounds, or kitty litter. Place them inside a container such as an empty yogurt or margarine tub and tape it shut. Your health department might know of a place to take old medicines. (Poison Prevention Tips)
At Christmas time don’t put presents like perfumes and after-shaves under the tree, but put them out of the reach of children. Clean up immediately after parties, so alcohol or cigarettes won’t be a temptation for children.
Mothballs should be hung in containers. If they are used in closets or chests, they should be put out of children’s reach. Bait traps should be tamper-resistant. Store bottles of alcohol in a locked cabinet far from kids’ reach, and remember that food extracts, such as vanilla and almond, may contain alcohol that can be harmful to kids.
When you have party guests designate a locked room where relatives and guests can place their coats and purses that may contain medications. Ingesting as few as six cigarette butts can send a child to the hospital, so you should empty ash trays often. Remove and empty partially filled glasses of alcoholic beverages. Be aware of any legal or illegal drugs that guests may bring into your home. Do not let guests leave drugs where children can find them, for example, in a pillbox, purse, backpack, or coat pocket. Be aware of all medications in your home (and in the homes of your relatives if your kids spend time there).
If relatives come to stay through the holidays, be sure their medications are put away. Lock medicines in a suitcase or, if in a purse, place it out of reach. Buy plastic plants with fake berries, not the real ones.
You should have the national poison hotline by each phone, the number is 1-800-222-1222. They will want to know the condition, weight, and age of the person. Have they been sick, and if so, what medications have they been on? Do they have any allergies? Also, have a poison first-aid chart at hand. (Poison First Aid) (Poison First Aid) (Emergency First-Aid Chart)
Here is some general advice for specific situations: Has the person collapsed or stopped breathing? Call 911 or your local emergency number right away. Do you have poison in the eyes? Then rinse your eyes with warm running water for 15 to 20 minutes. What about poison on your skin? You should take off any clothing that the poison touched, and rinse your skin with running water for 15 to 20 minutes. Have you Inhaled poison? You should get to fresh air right away. Did you swallow the wrong medicine or too much medicine? Then don’t take anything by mouth. Have you swallowed something that’s not food or medicine? You should then drink a small amount of milk or water. You should also keep a supply of ipecac syrup on hand (to induce vomiting if necessary).
Plants:
Identify all the plants in your home and yard by taking them into a nursery, greenhouse, or florist. Label the pots, and make a map of the yard. Don’t assume a plant is safe because birds or wildlife eat it. Remember that even a safe plant can be a choking hazard. You can try to remove material from a child’s mouth with a damp washcloth wrapped around your finger. Store seeds, bulbs, and plant food out of the reach of children. Seeds and bulbs might be coated with fungicides and insecticides. (Poisoncenter Brochure)
Teach children to not eat wild plants or mushrooms. It’s easy to confuse safe and unsafe ones. Unless you are an expert, you cannot tell poisonous mushrooms from safe mushrooms. Mushrooms that are called “death caps” (Amanita phalloides, Amanita verna) grow easily in yards and parks. Eating even a few bites can cause fatal liver damage. Mushrooms will often sprout up after a rain. Inspect your yard and remove them. If you do decide to go mushroom hunting get a good guide and read up. (Mushrooms Demystified by David Arora, The Mushroom Hunter’s Field Guide by Alexander Smith, and Mushrooms of North America by Orson K. Miller) You should note the environment, shape, color, odor, terrain, whether it is growing in a cluster or alone. Since many mushrooms are very similar, all of the characteristics must match for you to know what you have. Check for a fetid odor, signs of decomposition, or worm infestation. Try only a few at first, and set a few aside in case you are poisoned.
Dividing plants into safe and unsafe ones is a crude method of categorizing them. So, the list below is only a very rough guide, and, of course, it is far from complete. Ideally you should identify each plant you are likely to be exposed to by its scientific name, and know the degree and nature of its toxicity.

(1) Having said this, you can’t fully trust the instructions, since researchers have found they can be wrong. They have also found that local poison control centers will often be wrong, so the advice is to call the regional and national ones.
