Association between ambient particulate matter and daily cause-specific mortality in Tanggu, Tianjin Binhai New Area, China

Abstract

The aim of the study was to determine whether the area of Tanggu, Tianjin Binhai New Economic Developing Area, China, is subject to similar effects of PM10 similar to other areas of China. This study was designed to investigate cause-specific mortality risks associated with air pollution in this geographical region . The present study used time-series analysis to explore the relationship between PM10 and the cause-specific mortalities for non-accidental, cardiovascular and cardiopulmonary mortality from 1 January 2006 to 31 December 2010. A 10 μg/m3 increment of PM10 was associated with a 1.02% (95% confidence interval (CI), 0.48%, 1.56%) increase in cardiovascular mortality, and a 0.88% (95% CI: 0.36%, 1.39%) increase in cardiopulmonary mortality. In addition, the effects from PM10 appear to be consistent with multi-pollutant models. The results show there are strong associations between daily cardiovascular and cardiopulmonary mortality and ambient PM10 exposure.
