Region 1: EPA New England

Other Priority Air Toxics in New England

The air toxics of greatest concern in New England were selected due to risk modeling for only the inhalation route of exposure and these pollutants exceeded the health benchmarks in one or more of the New England states. There are several other air pollutants that EPA has acknowledged high concern due to their health impacts but these air pollutants aren't on the Air Toxics of Concern list. The absence of asbestos, dioxin, lead, mercury, PCBs and radon from the list is due to the fact that there may not be a health benchmark established yet or that exposure is through other routes, such as ingestion and not inhalation, or that there is inadequate information about emissions sources.
