可吸入颗粒物造成的健康损失价值核算--以吉林市为例

根据近年采国内外权威机构在可吸入颗粒物与健康效应关系上的研究成果，确定了单位污染物的增减与急慢性健康效应之间的暴露-反应函数关系。在此基础上建立了计算超额患病与死亡的数学模型，并阐述了支付意愿法、统计生命价值法、统计生命年价值法在健康损失价值核算上的应用。进而以吉林市为例，计算出2003年该市由可吸入颗粒物引起的健康损失及相应的经济价值。结果表明，吉林市2003年的建康损失价值因对死亡的估价方法不同分别为6．86亿元和4．28亿元，相当于当年GDP的2．17％和1．35％。

Accounting of Health-loss Value Induced by Inhalable Particulate Matter--A Case Study of Jilin City

According to the results from many well-done studies of domestic and international authoritative institutions on(relationship) of PM_(10) and health impact,our research identified the Exposure-Response functions in terms of acute and chronic effects associated with increase of unit pollutant.Then we set up the mathematical model to calculate the excess number of(patient) and death on the basis,and the application of those methods on accounting of economic loss due to health impact also be expatiated,such as willing to pay(WTP),value of statistics life(VOSL),value of life year(VOLY).As a real practice,we calculated the excess number of death and patient attributed to PM_(10) and corresponding economic loss of Jilin city in 2003.The result suggests that the loss is CNY 686 millions or CNY 428 millions of different methods on evaluating death,accounting for 2.17% or 1.35% of GDP.
