Triggering of cardiovascular hospital admissions by source specific fine particle concentrations in urban centers of New York State.

ABSTRACT: BACKGROUND:Previous work reported increased rates of acute cardiovascular hospitalizations associated with increased PM2.5 concentrations in the previous few days across urban centers in New York State from 2005 to 2016. These relative rates were higher after air quality policies and economic changes resulted in decreased PM2.5 concentrations and changes in PM composition (e.g. increased secondary organic carbon), compared to before and during these changes. Changes in PM composition and sources may explain this difference. OBJECTIVES:To estimate the rate of acute cardiovascular hospitalizations associated with increases in source specific PM2.5 concentrations. METHODS:Using source apportioned PM2.5 concentrations at the same NYS urban sites, a time-stratified case-crossover design, and co
