Abstract

Rationale: There are unexplained geographical and seasonal differences in the short-term effects of fine particulate matter (PM_2.5) on human health. The hypothesis has been advanced to include the possibility that such differences might be due to variations in the PM_2.5 chemical composition, but evidence supporting this hypothesis is lacking. Objectives: To examine whether variation in the relative risks (RR) of hospitalization associated with ambient exposure to PM_2.5 total mass reflects differences in PM_2.5 chemical composition. Methods: We linked two national datasets by county and by season: (1) long-term average concentrations of PM_2.5 chemical components for 2000-2005 and (2) RRs of cardiovascular and respiratory hospitalizations for persons 65 years or older associated with a 10-μg/m³ increase in PM_2.5 total mass on the same day for 106 U.S. counties for 1999 through 2005. Measurements and Main Results: We found a positive and statistically significant association between county-specific estimates of the short-term effects of PM_2.5 on cardiovascular and respiratory hospitalizations and county-specific levels of vanadium, elemental carbon, or nickel PM_2.5 content. Conclusions: Communities with higher PM_2.5 content of nickel, vanadium, and elemental carbon and/or their related sources were found to have higher risk of hospitalizations associated with short-term exposure to PM_2.5.
