摘要
本文通过对阿左旗2008年3-5月的空气总悬浮颗粒物浓度进行监测,分析该地区空气中颗粒物含量与沙尘天气状况。结果表明:根据空气总悬浮颗粒物浓度的沙尘天气分级标准,2008年3-5月大气中TSP平均浓度值分别为:0.556mg/m3,0.459mg/m3,0.395mg/m3,由3-5月总体呈现下降的趋势。阿左旗大气中TSP浓度符合国家环境空气质量二级标准。3-5月期间共发生9次沙尘天气,其中浮尘天气7次、扬沙天气2次。沙尘天气的频率以3月最高,4月其次,5月最低。
ZuoQi o this article through to 3 - 5, 2008 of air total suspended particle concentration monitoring, analysis the region particles content in the air and dust weather conditions, The results show that： According to the concentration of total suspended particulate matter air dust weather classification standard, 3 -5, 2008 average density TSP in the atmosphere are： 0. 556 mg/m3 after, 0. 459 mg/m3 after, 0. 395 mg/m3 after, from 3 to 5 month general downward trend, ZuoQi TSP concentration in the atmosphere o meet the national secondary standard of air environmental quality. 3 - 5 months a total of nine times during dust weather, including floating dust weather 7 times, flying sand weather 2 times. Sand and dust weather, the highest frequency of march to April second, lowest in May.
