Effect of exposure to ambient PM2.5 pollution on the risk of respiratory tract diseases： a meta-analysis of cohort studies

摘要

The International Agency for Research on Cancer and the World Health Organization have designated airborne particulates,including particulates of median aerodynamic diameter 25 μg/m^3 PM_(2.5).In conclusion,exposure to ambient PM_(2.5) was significantly associated with the development of respiratory tract diseases,especially in children exposed to high concentrations of PM_(2.5).
