TL;DR: It is suggested that PM2.5–mortality associations can vary greatly by source, and that the largest IHD health benefits per microgram/cubic meter from PM 2.5 air pollution control may be achieved via reductions of fossil fuel combustion exposures, especially from coal-burning sources.

TL;DR: Overall, although these intercomparisons suggest areas where further research is needed, they provide support the contention that PM2.5 mass source apportionment results are consistent across users and methods, and that today's sourceapportionment methods are robust enough for application to PM2-5 health effects assessments.

TL;DR: The results indicate that applying source apportionment methods to the nationwide CSN can be an informative avenue for identifying and quantifying source components for the subsequent estimation of source-specific health effects, potentially contributing to more efficient regulation of PM2.5.

TL;DR: The effects of PM2.5 on daily mortality vary with source, season, and locale, consistent with the hypothesis that PM composition has an appreciable influence on the health effects attributable to PM.

TL;DR: Adverse health associations were strongest with personal measures of EC exposure, suggesting that the diesel “soot” fraction of PM2.5 is most responsible for pollution-related asthma exacerbations among children living near roadways.
