متن کاملDevelopment of acute exposure guideline levels for airborne exposures to hazardous substances.
Hazardous substances can be released into the atmosphere due to industrial and transportation accidents, fires, tornadoes, earthquakes, and terrorists, thereby exposing workers and the nearby public to potential adverse health effects. Various enforceable guidelines have been set by regulatory agencies for worker and ambient air quality. However, these exposure levels generally are not applicab...
متن کاملCarcinogenic effects of chronic exposure to very low levels of toxic substances.
The sort of situation that I wish to consider is contamination of the air around vinyl chloride plants with low levels of vinyl chloride monomer. People living nearby would be exposed to it continuously for however many decades they lived there. If some cancers are caused by ambient levels of (say) 0.01 ppm, I want to discuss the likely effects on the numbers of cancers and the age distribution...
