100 percent of children are found to be exposed to excessive arsenic, dioxins and pesticides in latest study
July 21, 2013
A new study on dietary toxin exposure found that all the participating children exceeded the cancer benchmark levels for arsenic, dioxins, dieldrin, and DDE, while 95 percent of preschoolers exceeded the non-cancer benchmark for acrylamide.
More worrying was that the cancer risk ratios were exceeded 100-fold for arsenic and dioxins. Researchers at the University of California, Davis recently carried out the first-ever study to consider dietary exposure to 11 toxins simultaneously, including acrylamide, arsenic, lead, mercury, dioxins and several banned pesticides (chlordane, DDE, dieldrin). The study's participants included 364 children aged two to seven, 446 parents of young children, and 149 older adults, all living in California. To assess exposure levels, researchers used food-frequency questionnaires along with toxin content datasets from the Environmental Protection Agency. Exposure levels were then compared with the "cancer benchmark" of each toxin, which is the exposure level that would generate one excess cancer per million people over a 70-year lifetime. Non-cancer benchmark levels were also considered, for health effects other than cancer.
