摘要

The Environmental Protection Agency (EPA) promulgates standards for air pollutants and drinking water contaminants,as part of its mandate to protect public health and welfare.The Agency also assesses the health risks associated with hundreds of chemical substances,often developing quantitative toxicity and cancer potency benchmarks.This article compares EPA standards and benchmark values to those of other countries and other agencies.This includes the national ambient air quality standards (NAAQS),the national primary drinking water regulations (NPDWR),and benchmark values from the Integrated Risk Information System (IRIS).Results show that the NAAQS are generally comparable to or less strict than the air quality standards of other countries and international organizations.The NPDWR tend to be less strict than the water quality standards of other countries for inorganic chemicals,and they are more strict about as often as they are less strict for organic chemicals.Reference values for toxicity and cancer potency derived in EPA health assessments posted in the IRIS database are less stringent than those of other agencies about as often as they are more stringent,and they are often identical.Revisions to these values more often than not made them less stringent.These results suggest that EPA's standards and quantitative health assessments are not out of line with those of other agencies and other countries.
