Hi my name is Nigel Harland, I am 42 years old and was diagnosed 8 years ago. I read with interest two emails concerning the possible effects of chemicals on PD sufferers.For several years whilst working for a well known soft drinks maker (Schh..you know who..) as a Quality technician, I was in daily contact with Methanol which was used in two Quality Control processes, namely sterilisation of microbiology equipment and as a constituent in the testing of products for levels of saccharin, sodium benzoate and quinine. Whilst I was not aware of any ill effects at the time, I have often wondered whether this may have caused or contributed to my P.D. Any comments would be welcome.. Nigel Harland [log in to unmask]
