The research is on what the toxic compounds in the environment are that cause Parkinson's. Some of them that we use in Parkinson's models are ones that are traditionally used by farmers, for example, to clear fishing ponds. We have had hints all along that it could be very toxic to the brain among vulnerable populations, resulting in Parkinson's.
For us, then, how do we protect those populations from all the insults in our environment? And it's not just what farmers see, but what we see every day.
