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

The PM ISA reviews information spanning scientific disciplines including atmospheric science, exposure, dosimetry, to assess the health and welfare effects related to particulate matter.

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.
