7 ways to cancer-proof your home
BPA, or bisphenol A, has been in the headlines endlessly the past couple of years, but that doesn't mean we know what to do about it, since the news has been both alarmist and confusing. Here's the lowdown: BPA is a phthalate and a synthetic estrogen linked to cancer, reproductive problems, and heart disease. In 2010, the President's Cancer Panel recommended that consumers not use water bottles and other containers made with BPA and urged that the ingredient be removed from commercial production, but that has happened in only a handful of states. Still, BPA-free bottles are now manufactured by all of the major bottle manufacturers, and BPA-free bottles are fast becoming the norm, at least where they are available. Unfortunately, BPA has been much slower to phase out in other products, such as the lining of cans. Because BPA can react with the metal of the cans, and cans are heated as they're sterilized, canned food is "high risk" for BPA.
Another ingredient used to make plastics more pliable is diethylhexyl adipate (DEHA), which is also classified as a possible carcinogen. DEHA is in almost all plastic wraps and has properties similar to phthalates, like BPA. Unlike BPA, it has yet to be phased out of most products.
Heating plastic does make it more likely that any chemicals contained in it will be released into food, so do not microwave food in any plastic container, and don't cover bowls and other containers with plastic wrap when heating.
Safer substitute: Look for "BPA-free" on labels. Use metal water bottles when you're out, a filtered water pitcher when you're home. Or get a built-in filter attachment for your faucet. Microwave food in glass or ceramic containers.
An odorless, radioactive gas that's produced by the natural decay of uranium, radon is more common than you might think. After smoking, it's the leading cause of lung cancer in the United States, according to the Environmental Protection Agency, which has found that nearly 1 in 3 homes checked in seven states had radon levels over 4 pCi/L, the EPA's recommended action level for radon exposure. Radon is a naturally occurring radioactive gas that comes from rock and soil; well water can also be a source of radon, as it's water soluble. The only way to find out if there's radon in your home is to test for it. Call the National Safety Council's National Radon Hotline at (800) 767-7236 and they'll send you a low-cost radon detector; inexpensive models are also available at most hardware stores.
Safer substitute: There's no safe substitute for radon; you don't want it in your home. Getting rid of it once you detect it is a job for professional radon mitigators.
6. Nonstick Cookware
Pots, pans, and other cookware made with a nonstick coating (Teflon) have been controversial for many years. The main chemical in nonstick coatings is perfluorooctanoic acid (PFOA), which is known to cause cancer. The question has been whether enough PFOA gets into the human body from pans to pose a risk. Some experts believe that PFOA and as many as 15 other chemicals can be released when cooking with these coatings, particularly at high heat. Other concerns involve whether the chemicals can get into food once the surface becomes scratched and nicked over time. The EPA has called on manufacturers to phase out PFOA, but it hasn't happened yet. The takeaway: Don't use nonstick pans to cook foods over 300 degrees, and toss them when the coating gets scratched.
Safer substitute: Glass, cast iron, copper, and ceramic or porcelain-coated pans are all safe. There are also lines of nonstick cookware made with other surface coatings (often ceramic, titanium, or both) that are PFOA-free.
7. Garden Chemicals
Several common ingredients in pesticides and weed killers have been linked with cancer and Parkinson's. A 2009 study found a higher incidence of brain cancer in children whose parents had extensive prior exposure to pesticides, herbicides, and fungicides, either at home or at work. The researchers identified the pesticides and herbicides classified by the EPA as probable or possible human carcinogens (including chlordane, heptachlor, tetrachlorvinphos, carbaryl, propoxur, lindane, dichlorvos, phosmet, and permethrin) as the likely toxins responsible the children's cancer.
Parkinson's is also being studied for links to pesticide exposure. One study found that people diagnosed with Parkinson's are more than twice as likely to report pesticide exposure than people not diagnosed with the disease. In-home insecticides have also been studied for links to cancer. One study found that elevated levels of two chemicals used in pest bombs, known as "total release foggers" or TRFs, were detected at high levels in the urine of children with leukemia. The EPA now tracks illnesses and deaths associated with foggers, and many states are working to get them reclassified as limited-use products.
Safer substitute: Learn to garden organically, and pull weeds by hand. If you have a pest problem in the house, do your best to control it with natural repellents, or at least without airborne sprays. If you have to spray or bomb, send everyone away and air the house out for a day before coming back in.
