摘要
根据2006年4、5月的观测数据,对通辽市科尔沁区空气质量进行了详细的对比分析,结果表明:市区与郊区SO2、NO2在4、5月份均不超标,TSP在4月份不超标,5月份却严重超标.市区SO2、NO2、TSP的浓度普遍高于郊区.利用空气污染指数评价空气质量,得出4月份空气质量较好,能够达到二级标准;而5月份空气质量较差,达到五级重度污染.郊区的空气质量比市区的好,空气质量除受人为因素影响之外,受自然因素影响也很大,降水和风速是TSP的主要影响因子.
According to observation data of April and May in 2006, the ambient air quality in Tongliao city Korqin area has been carried on the detailed contrast and analysis, The results showed that SO2, NO2 in April and in May in the urban district and suburb does not exceed the allowed figure, TSP density in April does not exceed, in May seriously exceeds the standard. Urban district SO2, NO2, the TSP density generally is higher than the suburb. Using the air pollution index appraisal air quality, indecate in April air quality is better and can achieve levels of Ⅱ standards; In May the air quality is worse, achieves five levels of specific weights pollution. Suburb air quality is better than urban district. The natural factor influence on the air quality to the extend, the precipitation and the wind speed are major effect factor of the TSP.
