摘　　要：据开县2010～2012年的空气质量数据，分析了开县的大气污染特征．并针对不同年龄组人群计算健康危险度（HR）值。结果表明，2010～2012年开县大气主要污染物是PH10,3年的平均值分别为0．12mg／m^2、0．13mg／m^2、0．14mg／m^3。开县大气污染主要是受污染源、气象条件等诸多因素影响。比较HR值可见，儿童组PMlo的HR值最大，因此在大气污染物控制中应以儿童为基准。According to the data of air quality in Kaixian County during 2010 - 2012, the characteristics of air pollution was analyzed and health risk （HR） value for different age groups was calculated. The results indicated that the main pollutant is PM10 and the average values is 0.12mg/m^3, 0.13mg/m^3,and 0.14mg/m^3,respectively during 3 years in Kaixian County; Air pollution is mainly affected by the sources of pollution, weather conditions and so on. Comparison of HR, the HR-PM10 of children＇s group is the maximum value, so air pollution control should be based on the child as a reference.
