George - I'm interested, but have no specialised knowledge. But say you did know your PD could be/was caused by clordane (or whatever) is it too simplistic to look for possible source/s, eliminate possibilities of contact, hope to prevent progression? I heard a program recently that linked a chemical - ? hexane - with noise pollution suffered by factory workers as combined factors in increased incidence of brain disease/tumours. I will try to get hold of a transcript. Beth L. On Sat, 7 Dec 1996, George Campbell wrote: > I need to learn about environmental causes of parkinson`s. Is this idea > valid?
