To construct the air quality health index (AQHI) by inclusion of air pollutants PM(2.5) and O(3) in Guangzhou, Shanghai, Xi' an, Beijing, Shenyang, and explore scientificity and feasibility of its application in China. The daily average concentrations of PM(2.5) and O(3) in air, and daily average mortality from 2013 to 2015 in the 5 cities in China, the exposure-response coefficients of PM(2.5) and O(3) and total mortality from Meta studies in China were used to construct local AQHI. The health risk levels of air pollution in the 5 cities were calculated and compared with the characteristics of single pollutant concentrationof PM(2.5) or O(3). In the 5 cities, the average concentration of PM(2.5) was highest in Beijing (82 μg/m(3)) and lowest in Guangzhou (46 μg/m(3)). And the average concentration of O(3) was highest in Shanghai (72 μg/m(3)) and lowest in Xi' an (45 μg/m(3)). In all the cities, the average concentration of PM(2.5) was highest in winter and lowest in summer. In summer, the average concentration of O(3) was lowest. But the health risk level of AQHI showed that the 5 cities had higher frequency of low or medium risk averagely. And Beijing had the highest frequency of high risk in summer (5.69%). Xi' an had the highest frequency of extremely high risk in winter (1.63%). In this study, AQHI could be constructed by using air PM(2.5) and O(3) concentration data which can be obtained in many areas in China. The application of this index is scientific and feasible in China.
通过纳入空气污染物细颗粒物(PM2.5)和臭氧(O3)构建广州、上海、西安、北京、沈阳的空气质量健康指数(AQHI),并探讨其在中国应用的科学性和可行性。利用中国这5个城市2013年至2015年空气中PM2.5和O3的日均浓度、日均死亡率,以及中国Meta研究中PM2.5和O3的暴露-反应系数与总死亡率来构建本地AQHI。计算这5个城市空气污染的健康风险水平,并与PM2.5或O3单一污染物浓度特征进行比较。在这5个城市中,北京的PM2.5平均浓度最高(82微克/立方米),广州最低(46微克/立方米)。O3的平均浓度上海最高(72微克/立方米),西安最低(45微克/立方米)。在所有城市中,PM2.5的平均浓度冬季最高,夏季最低。夏季O3的平均浓度最低。但AQHI的健康风险水平显示,这5个城市低风险或中风险的平均出现频率较高。北京夏季高风险出现频率最高(5.69%)。西安冬季极高风险出现频率最高(1.63%)。本研究表明,利用中国许多地区均可获取的空气PM2.5和O3浓度数据能够构建AQHI。该指数在中国的应用具有科学性和可行性。
