Impact on human health due to different PM10 controlling targets in Pearl River Delta in 2006 |
|
|
Abstract Concentration of PM10 was measured at 16 typical sites in Pearl River Delta in 2006. Both Poisson regression model and life table method were used to calculate the health benefits due to controlling PM10 concentration in Pearl River Delta. The annual mean concentration of PM10 was found to reach 73μg/m3. For adults (older than 30), the avoidable deaths would be 2300 person and the life expectancy of residents would prolong 0.13 year, if the annual mean PM10 concentration reduced to the national air quality specification Level II of PM10. If the PM10 controlling targets recommended by WHO could be reached, the avoidable deaths would be 8700 person (70μg/m3), 19700 person (50μg/m3), 32600 person (30μg/m3) and 38500 person (20μg/m3), respectively, and life expectancy of residents would prolong 0.47 year (70μg/m3), 1.1 years (50μg/m3), 1.9 years (30μg/m3) and 2.3 years (20μg/m3).
