Evidence grows linking Parkinson's disease to pesticide exposure



Put down the Raid and back away slowly: Scientists are growing more
confident that long-term exposure to toxic substances, notably
pesticides, is implicated in most cases of Parkinson's disease.
Researchers first made a link between Parkinson's and paraquat, a
weedkiller long popular around the world, in the early 1980s. Since
then, hundreds of studies of animals, at least 40 of human patients,
and three of human brain tissue have found "a relatively consistent
relationship between pesticide exposure and Parkinson's," according to
British scientists whose research was published in a recent issue of
the journal Environmental Health Perspectives. Without these
environmental exposures, researchers think, people would still get
Parkinson's, but in smaller numbers and later in life. Over 1 billion
pounds of pesticides are used in U.S. farms, gardens, and households
every year.
