Integrated Science Assessment (ISA) for Particulate Matter (Final Report, Dec 2019)

On this page:

Overview

The Integrated Science Assessment (ISA) for Particulate Matter is a concise synthesis and evaluation of the most policy-relevant science, and has been prepared as part of the review of the primary (health-based) and secondary (welfare-based) National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM) under the Clean Air Act. Welfare effects are non-health effects which, according to the Clean Air Act include, but are not limited to, effects on soils, water, crops, vegetation, animals, wildlife and climate. The PM ISA, in conjunction with additional technical and policy assessments, provides the policy relevant scientific information necessary to conduct a review of the current primary and secondary air quality standards for particulate matter sufficiently protects public health and welfare.

Background

Particulate matter is one of six principal (or criteria) pollutants for which EPA has established National Ambient Air Quality Standards (NAAQS). The Clean Air Act requires EPA to periodically review the science for six major air pollutants, including PM.

The Integrated Science Assessments (ISAs) summarize the science related to the health and welfare effects associated with these pollutants by providing a comprehensive review of the policy-relevant scientific literature published since the last NAAQS review. The ISA is a critical part of the scientific basis for updating the NAAQS.
