区域环境空气中苯并[a]芘容量研究

Study on the Environmental Capacity of Benzo[a] Pyrene (BaP) in Regional Ambient Air

用重量法和高效液相色谱法对朔州市朔城区(无焦区)和清徐县(产焦区)环境空气中TSP、PM10、Ba P进行环境监测和评价,并选用EIAPro A2008软件与AERMOD模型对该区域环境空气中的苯并[a]芘进行环境空气容量研究。结果表明:控制区空气中Ba P污染超标,软件预测值与监测值相符,PM10与Ba P浓度的相关性高,并确定朔州市朔城区的Ba P环境容量为16.77 kg·a-1,清徐县城区的Ba P环境容量为25.17 kg·a-1。

By using the weight method and HPLC method, this paper carries out the environmental monitoring and evaluation on TSP, PM10 and BaP in ambient air of Shuocheng District （no coke area） and Qingxu County （coke producing area） in Shuozhou City, and carries out the study on BaP capacity in ambient air of these areas by using the software EIAProA2008 and model AERMOD. The results show that the BaP pollution in the air of control area exceeds the standard, the software predicted value conforms to the monitoring value, the correlation between PM10 and BaP concentration is high, and the BaP environmental capacity of Shuocheng District is determined as 16.77 kg ·a-1, and the BaP environmental capacity of the urban area of Qingxu County is determined as 25.17 kg· a-1.
