New research has found that combined exposure to background levels of the pesticides ziram and paraquat as well as combined exposures to the pesticides maneb and paraquat in workplaces and residences substantially increased the risk of Parkinson’s Disease. Those exposed to ziram, maneb, and paraquat together experienced the greatest increase in PD risk. The results suggest that combined exposures to pesticides may act together to increase the risk of PD.
