Body Burdened: CDC Study Finds Widespread Exposures to Phthalates, Pesticides and Other Chemicals

—DEET: The insect repellent ingredient DEET was found in only 5 to 10 percent of the people tested, and probably reflects individual use. Its absorption through the skin is limited, so many of these exposures come from eating food touched by DEET-treated hands. DEET has not been linked to cancer but may cause allergic reactions and neurological effects including seizures. Wear light cotton clothing to keep the insects away. If using repellent, wash hands after you apply it. For suggestions on natural repellent products, see "Outsmart the Biters" and the Insect Repellent Product Report.

—Chlorpyrifos: A metabolite of the pesticide chlorpyrifos and its sister chemical, chlorpyrifos methyl, was found throughout the population. Chlorpyrifos, a neurotoxin, was banned for residential use in the last few years, but chlorpyrifos methyl is still used in agriculture. Children ages 6 to 11 had higher levels of the metabolite than teens or adults. The study also uncovered the widespread presence of a metabolite of the widely used herbicide, 2,4-D, considered by the International Agency for Research on Cancer (IARC) as possibly carcinogenic to humans. Choose integrated pest management strategies whenever possible around the home. See the Lawn Care Product Report and "Nontoxic Pest Control."
