Rudy West & all: I have a book titled Environmental Neurotoxicology, published by the National Research Council that you might be interested in. It may be ordered over the internet through the National Academy Press. It contains a wealth of information concerning studies involving toxic substances and their relation to diseases. I believe it costs about $26.00. It's very interesting. The National Academy Press also has a huge amount of other papers, booklets, and brochures available (some are free, I think), on various subjects-not just medical. (I was doing research on my thesis, on a different topic, when I discovered it.) Rosemary Russell [log in to unmask]
