Summary: Prior studies suggested that air pollution exposure may increase the risk of Parkinson's Disease (PD). Researchers investigated the long-term impacts of traffic-related and multiple sources of particulate air pollution on PD in central California. They assessed exposure at residential and occupational locations from 1981 to 2016, estimating annual average carbon monoxide (CO) concentrations, a traffic pollution marker.

Findings: Authors found that long-term modeled exposure to local traffic-related air pollution (CO) and fine particulates from multiple sources (PM2.5) at homes and workplaces in central California was associated with an increased risk of PD.
