For decades, Khoji Wesselius has noticed the oily scent of pesticides during spraying periods when the wind has blown through his tiny farming village in a rural corner of the Netherlands. Now, after volunteering in an experiment to count how many such substances people are subjected to, Wesselius and his wife are one step closer to understanding the consequences of living among chemical-sprayed fields of seed potato, sugar beet, wheat, rye and onion. "We were shocked," said Wesselius ... who had exposure to eight different pesticides through his skin, with even more chemicals found through tests of his blood, urine and stool. "I was contaminated by 11 sorts of pesticides. My wife, who is more strict in her organic nourishment, had seven sorts of pesticides." Regulators closely monitor dietary intake of pesticides when deciding whether they are safe enough for the market, but little attention has been paid to the effects of breathing them in or absorbing them through the skin. According to a new study, even people who live far from farms are exposed to several different types of pesticides from non-dietary sources. The researchers got 641 participants in 10 European countries to wear silicone wristbands continuously for one week to capture external exposure to 193 pesticides. In laboratory tests, they detected 173 of the substances they tested for, with pesticides found in every wristband and an average of 20 substances for every person who took part.
