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


U.S. EPA. Integrated Science Assessment (ISA) for Particulate Matter (Final Report, Dec 2019). U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-19/188, 2019.


The PM ISA ERD reflects a systematic evaluation of the peer-reviewed literature published since the completion of the 2009 PM ISA that builds off the scientific conclusions presented in previous assessments of the health and welfare effects evidence for PM. This ISA is the initial draft of the current state of the science on the health and welfare effects of PM that will ultimately result in the final PM ISA that will serve as the scientific foundation of the ongoing review of the PM NAAQS, which was last completed in 2012.


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.
