2009—2011年包头市大气中颗粒物浓度分析

本文通过对内蒙古包头市2009—2011年PM10浓度和TSP浓度的测定，分析了大气中颗粒物浓度的含量状况。结果表明：2009年3月到9月份之间，出现6次沙尘天气，并且颗粒物浓度超过大气空气质量三级标准，其中最严重的一次PM10浓度达到1．147mg／m^3。PM10浓度一天的变化中，在下午5时和晚间10时达到两个峰值，分别是1．608mg／m^3和1．882mg／m^3。2010年中十一月份的TSP日平均浓度较高，比八月份TSP浓度高7倍。2011年春季空气中颗粒物污染较重，在沙尘天气发生期间，颗粒物浓度含量较高

From 2009 to 2011 particulate matter concentrations in the atmosphere in Baotou

Through to the Inner Mongolia Baotou city of PM10concentration and the TSP concentration t from 2009 to 2011 , this article analyzes the content of particulate matter concentration in atmosphere condition. Results show that ： In 2009 between March to Sep- tember, appeared six times of sand and dust weather, and particle concentration more than atmospheric air quality level 3 standards, one of the most serious of PM10 concentration is 1. 147 mg/m3. PMloconcentration change in a day, five in the afternoon and ten in the evening when peak two, respectively is 1. 608 mg/m3 and 1. 882 mg/m3. In November 2010 years TSP daily average concentration is higher, than 7 higher in August . The particulate of the environment air polluted heavy in 2011 during the spring in Baotou, the principal reason that affected environment air quality was dust weather .
