Comparison of hazardous air pollutant health risk benchmarks

Article Abstract:

The environmental Protection Agency's (EPA) Reference Dosage and Reference Concentration data and the US Agency for Toxic Substances and Disease Registry's chronic Minimal Risk Level data appear to have similar health risk endpoint estimates for most chemicals. The discrepancies found in some estimates could be due to the different uncertainty factors and differences in the selection and interpretation of studies that were used to assess health risks.

Who will be protected by EPA's new ozone and particulate matter standards?

Article Abstract:

Results reveal that the upper income population would benefit the most from air quality improvements in current and additional non-attainment areas brought about by the Environmental Protection Agency's (EPA) new ozone and particulate matter standards. Inequitable distribution of air pollution impacts have always existed and may need to be remedied with the imposition of specific equity-targeted policies.
