The Ambient Particular Matter Pollution Situation and its Health Effect in China

Abstract

Abstract-Particular matter is the main pollutant for the ambient environment in China. Some PM 10 pollution index data were analyzed for four different cities. Exposure-response between PM 10 , PM 2.5 and daily mortality of inhabitants in China was discussed. Epidemiological literature of PM 10 , PM 2.5 and daily mortality were extracted using Endnote, and the relationship between PM 10 , PM 2.5 and daily mortality of inhabitants using meta-analysis method. The results show that the air pollution index average value is 92.8, 74, 67.9 and 75.1 for Beijing, Shanghai, Guangzhou and Chongqing, respectively. It is more serious for PM 10 pollution in Beijing than other three cities. The daily mortality of inhabitants increase by 0.29% (95% CI: 0.21%-0.38%) and 0.56% (95% CI: 0.40%-0.72%), as the concentration of PM 10 , PM 2.5 increase a certain degree (10µg/m³). The results of meta-analysis can provide the scientific basis for particular matter pollution control. The related control measurements should be made to reduce PM pollution.
