Abstract:Comprehensive exposure-response coefficients were obtained based on Meta-analysis of epidemiologic studies, and then by using ozone concentration data from Pearl River Delta regional air quality monitoring network, human health impacts of ozone pollutant in Pearl River Delta region during 2006~2012were assessed based on Relative Risk Model. The results of Meta-analysis show that as the concentration of ozone increased 10mg/m3, the mortality for non-accidental, cardiovascular disease and respiratory disease increased 0.45% (95% confidence interval (CI): 0.40%~0.50%), 0.70% (95% CI: 0.57%~0.86%) and 0.64% (95% CI: 0.47%~0.86%), respectively. Health impact assessments indicate that due to the growth of ozone concentration and exposed population, the ozone-attributable mortality was on the 3times rise from 2006 to 2012, and the rising ozone concentration had contributed more than 2/3 of the mortality increment. The estimated annual average numbers of attributable mortality of non-accidental, cardiovascular disease and respiratory disease were 3982 (95% CI: 3543~4420), 1894 (95% CI: 1546~2319) and 1128 (95% CI: 830~1508), respectively. Sensitivity analysis reveals that the mortality estimation appeared large deviation as parameter change, demonstrating urgent request of more accuracy parameters.
