UCLA study links chlorpyrifos exposure to elevated Parkinson's risk
A UCLA-led study published in Springer Nature Link found long-term exposure to chlorpyrifos associated with a more-than-2.5-fold increase in Parkinson's risk in humans, with mice and zebrafish experiments showing brain effects; the study is observational and cannot prove causation, and researchers note limitations such as unmeasured diet and lifestyle factors while regulators reassess chlorpyrifos use.
