The burden of air pollution on years of life lost in Beijing, China, 2004-08: retrospective regression analysis of daily deaths.

ABSTRACT:

Objectives

To better understand the burden of air pollution on deaths, we examined the effects of air pollutants on years of life lost (YLL) in Beijing, China.

Design

Retrospective regression analysis using daily time series.

Setting

8 urban districts in Beijing, China.

Participants

80 515 deaths (48 802 male, 31 713 female) recorded by the Beijing death classification system during 2004-08.

Main outcome measures

Associations between daily YLL and ambient air pollutants (particulate matter with aerodynamic diameter <2.5 µm (PM2.5), PM10, SO2, and NO2), after adjusting for long term trends, seasonality, day of the week, and weather conditions. We also examined mortality risk related to air pollutants.

Results

Mean concentrations of daily PM2.5, PM1
