But in the field of hazardous materials, aren't the regulations based on

extrapolations from high dose lab results with no corresponding

epidemiological studies?  I may be way off base, but I thought that's the

method the EPA uses to set environmental standards for chemicals - Ames

tests extrapolated to "1 in a million" cancer risk.
