Environmental Exposures and Parkinson’s Disease [PDF]
International Journal of Environmental Research and Public Health, 2016 Parkinson’s disease (PD) affects millions around the world. The Braak hypothesis proposes that in PD a pathologic agent may penetrate the nervous system via the olfactory bulb, gut, or both and spreads throughout the nervous system. The agent is unknown, but several environmental exposures have been associated with PD.

Environmental Exposures and Hearing Loss [PDF]
International Journal of Environmental Research and Public Health, 2020 Pollutants that contaminate the natural or built environment adversely affect the health of living organisms. Although exposure to many of them could be avoided or minimized by careful preventive measures, it is impossible to totally avoid exposure to all pollutants.
