根据榆林市2006-2011年SO2、NO2和PM10的监测数据，利用美国环保局推荐的健康风险评价模型，对榆林市区大气中1主要污染物通过呼吸途径对人体的健康风险进行了研究。研究表明：(1) SO2和 NO2的分布有明显的季节变化规律，冬季高于夏季；PM10污染高峰期出现在每年的一、二季度，受风沙天气影响严重；(2)不同人群因吸入SO2和NO2所导致的健康风险在1.96499×10-9~9.85147×10-9之间，总风险值在4.49746×10-9~1.343254×10-8之间，远小于最大可接受风险水平，其中成年男性的非致癌风险最高，其次是成年女性和儿童。

By analyzing the monitoring data of SO2 , NO2 and PM10 from 2006 to 2011 with Health Risk Assessment Model recommended by U. S Environmental Protection Agency, the paper makes a health risk assessment on main air pollu-tants in Yulin. Results shows that 1 ) SO2 and NO2 content, which varies with seasons, is higher in winter and lower in sum-mer;2) because of the dusty weather, the content of PM10 reaches peak in the first and second quarter of a yea; 3) the health risk caused by SO2 and NO2 inhalation is from 1. 964 99 × 10 -9 to 9. 851 47 × 10 -9, which is much less than the total health risk 4. 497 46 × 10 -9 to 1. 343 254 × 10 -8;4)the non-carcinogenic risk of man is the highest, following by women and children.
