> There are several types of proof. Nick Ashford and I observed the same patterns of inexplicable new-onset intolerances across very different toxic exposures in over a dozen countries. Sheep dippers using organophosphate pesticides in rural areas of Europe, radiology workers inhaling chemicals while developing films in New Zealand, Gulf War veterans, EPA workers in a remodeled and poorly ventilated office building in 1987, cleanup crews breathing fumes after oil spills. Many would get ill, and a small percentage never recovered. They became exquisitely sensitized, as well as disabled.

This doesn't really sound that crazy to me. People working with industrial chemicals need protection. This is a widely known and accepted fact. It doesn't point to the entire population getting sick from small doses of chemicals in their day to day lives, like the flame-retardants in their mattresses, as the article opens up claiming.
