Fine Particle Constituents and Mortality: A Time-Series Study in Beijing, China.

ABSTRACT: There is a rising concern that fine particle (PM_2.5) compositions may play an important role in explaining PM_2.5-related mortality risks. However, PM_2.5 constituents responsible for these risks have not yet been determined. To date, there are few PM_2.5 constituent health studies in developing countries. We adopted a time-series approach, using generalized linear regression models to examine associations between short-term exposure to PM_2.5 constituents and mortality. We analyzed data stratified by sex and by age groups (<65, 65-74, and >74) from 2013 to 2015 in Beijing, China. We also investigated seasonal patterns of such associations. For a 0 day lag, interquartile range increases in potassium, calcium, magnesium, and organic carbon
