Air Pollution and Parkinson's

The University of Toronto has released a new study that ties manganese air pollution produced by industries such as steel foundries to a high risk of Parkinson’s. The study was conducted using 110,000 subjects living in Toronto and Hamilton over a three year period and appears in the July issue of Environmental Research.

The researchers compared the effect of manganese exposure through air pollution generated by vehicles and that generated from industrial sources. They found no association between traffic-generated manganese and Parkinson’s. But exposure to ambient manganese from sources such as steel foundries appeared to add to the natural loss of brain neurons, possibly accelerating the aging process and contributing to the advancement of Parkinson’s disease.
