Dear Jennifer and Hilary: This is just to minimize your apprehension of chemically induced PD. I was a research chemist in various laboratories after receiving my degree. I have been exposed to a great many chemical substances ranging from a great many solvents from hydrocarbons to chlorinated and sulfated and hydroxylated to polly wolly glycol and all kinds of chemicals encountered in an analytical laboratory including fertilizers, polymers, naval stores, and all sorts of antibiotics. In all my years in the lab, I have never met or become aware of any one becoming afflicted with Parkinson. I have had mishaps with different solvents like burning my eyes with boiling chloroform, but none of my medical problems are due to exposure to various chemicals. So, be at ease, and think of how you can better 'seize the day' and enjoy whatever you still can. Love Michel Margosis
