People who used the pesticides paraquat or rotenone develop Parkinson’s disease approximately 2.5 times more often than those who have not used pesticides. Obviously, these pesticides are toxic to nervous tissue. According to Freya Kamel, Ph.D., a researcher in the intramural program at NIEHS and co-author of the paper appearing online in the journal Environmental Health Perspectives, "Rotenone directly inhibits the function of the mitochondria, the structure responsible for making energy in the cell, and paraquat increases production of certain oxygen derivatives that may harm cellular structures. People who used these pesticidesnor others with a similar mechanism of action were more likely to develop Parkinson's disease." Paraquat has long been restricted and rotenone is only to be used to kill invasive fish species; therefore, these pesticides are not used at home.
