WASHINGTON (AFP) – US researchers said Friday they have found that people who used two specific varieties of pesticide were 2.5 times as likely to develop Parkinson’s disease.

The pesticides, paraquat and rotenone, are not approved for house and garden use. Previous research on animals has linked paraquat to Parkinson’s disease, so it is restricted to use by certified applicators.

Rotenone is approved only for use in killing invasive fish species.

“Rotenone directly inhibits the function of the mitochondria, the structure responsible for making energy in the cell,” said study co-author Freya Kamel, a researcher at the National Institute of Environmental Health Sciences.

“Paraquat increases production of certain oxygen derivatives that may harm cellular structures. People who used these pesticides or others with a similar mechanism of action were more likely to develop Parkinson’s disease.”

The study examined 110 people with Parkinson’s disease and 358 people who served as a control group from the Farming and Movement Evaluation (FAME) Study.

FAME is part of a larger Agricultural Health Study looking at the health of approximately 90,000 licensed pesticide applicators and their spouses.

The study appears in the journal Environmental Health Perspectives.

    Which government agents applied paraquat on pot plants? Look at the way the farmers vote. Good examples come from the book, “What’s The Matter With Kansas.” When you drive around Oregon where the farmers are, everyone one of them have huge signs up during the elections for the tories. Yes, they are using some “chemical” in their mix to give them Alzheimer’s, and/or FAUX NEWS Old Geezer Syndrome.”

    Were those chemicals produced by Dow Chemical where my father worked for 40 years? That would explain why he and other loved ones in the town had/have to suffer.
