自2000年以来，山西省政府采取了多项举措并强制关闭工厂，以减少燃煤排放和工业化对环境的影响。我们使用伤残调整生命年 (DALY) 估算了山西省太原市 2001 年至 2010 年与空气质量改善相关的健康效益，并使用统计生命值 (VOSL) 将健康效益货币化。收集了 2001 年至 2010 年太原市空气动力直径小于 10 pm 的颗粒物 (PM10) 年平均浓度和相关健康结果的数据。使用选定的暴露响应函数来计算 10 年间每年由 PM10 引起的死亡或疾病病例。将这些数据相加，计算出 2001 年至 2010 年间每年损失的伤残调整生命年 (DALY) 及其与 PM10 相关的货币价值。据估计，2001 年至 2010 年期间空气质量的改善避免了 2810 例过早死亡、951 例新发慢性支气管炎病例、141,457 例门诊就诊、969 例急诊室就诊和 31,810 例住院治疗。 DALYs（VOSL）从2001年的52,937人（72.74亿元人民币）下降到2010年的22,807人（34.42亿元人民币），下降了56.92%（52.68%）。过早死亡占DALYs总数的近95%。我们的分析表明，太原过去十年的空气污染治理已经产生了巨大的健康效益。 (C) 2014 年作者。由爱思唯尔有限公司出版
Since 2000, the government in Shanxi province has mounted several initiatives and mandated factory shutdowns with the goal of reducing coal burning emissions and the environmental impacts of industrialization. We estimated the health benefits associated with air quality improvement from 2001 to 2010 in Taiyuan, Shanxi Province, using disability-adjusted life years (DALYs) and monetized the health benefits using value of statistical life (VOSL). Data were collected on annual average concentrations of particulate matter less than 10 pm in aerodynamic diameter (PM10) and relevant health outcomes in Taiyuan from 2001 to 2010. Selected exposure response functions were used to calculate the cases of death or disease attributable to PM10, annually over a 10-year period. These were summed to calculate the DALYs lost and their monetary value associated with PM10 each year between 2001 and 2010. Air quality improvement from 2001 to 2010 was estimated to have prevented 2810 premature deaths, 951 new cases of chronic bronchitis, 141,457 cases of outpatient visits, 969 cases of emergency-room visits and 31,810 cases of hospital admissions. The DALYs (VOSL) decreased by 56.92% (52.68%) from 52,937 (7274 million Yuan) in 2001 to 22,807 (3442 million Yuan) in 2010. Premature deaths accounted for almost 95% of the total DALYs. Our analysis demonstrates that air pollution abatement during the last decade in Taiyuan has generated substantial health benefits. (C) 2014 The Authors. Published by Elsevier Ltd.
