EPA is announcing the availability of the final report, Provisional Assessment of Recent Studies on Health Effects of Particulate Matter Exposure. This report presents the findings of EPA’s survey and provisional assessment of studies published since the completion of the 2009 PM ISA. EPA has screened and surveyed the recent literature and developed a provisional assessment that places those studies of potentially greatest relevance to the current PM NAAQS review in the context of the findings of the 2009 PM ISA.
