Ecological Study on Global Health Effects due to Source-Specific Ambient Fine Particulate Matter Exposure.

ABSTRACT: Ambient air pollution of fine particulate matter with diameters less than 2.5 μm (PM_2.5) is associated with millions of premature deaths per year, recognized as a leading global health concern. The dose-response relation between ambient PM_2.5 exposure and mortality risk is the most fundamental information for assessments of the health effects of PM_2.5. The existing dose-response relations were generally developed based on the assumption of equal contribution to toxicity from various sources. However, the sources of PM_2.5 may significantly influence health effects. In this study, we conducted an ecological study to investigate the global long-term correlation between source-specific PM_2.5 exposure and cause-specific mortality risk (SPEC
