Head Injury and Proximity to Paraquat Increases Likelihood of Parkinson’s and other Health GIS News
A new study shows that people who have had a head injury and have lived or worked near areas where the pesticide paraquat was used may be three times more likely to develop Parkinson’s disease. The study is published in the November 13, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology. Paraquat is a herbicide commonly used on crops to control weeds. It can be deadly to humans and animals. ...
The study involved 357 people with Parkinson’s disease and 754 people without the disease, all of whom lived in an agricultural area in central California. The participants reported any head injuries they had ever received with a loss of consciousness for more than five minutes.
The researchers determined participants’ exposure to the weed killer based on a 500-meter area around their home and work addresses, using a geographic information system (GIS) that combined data on paraquat use collected by the state of California’s Pesticide Use Reporting system with land use maps.
