重工业区空气和大气干湿沉降物中多环芳烃的污染特征
Pollution characteristics of polycyclic aromatic hydrocarbons in the air and atmospheric deposition of heavy industrial district
摘要
Abstract
In order to determine the pollution of polycyclic aromatic hydrocarbons in the air and atmospheric deposition of heavy industrial city,the air passive sampler and atmospheric wet and dry deposition in Liuzhou Iron and Steel Group co. ,LTD. ,and Shuangchong village,are studied by component spectra of 16 kinds of polycyclic aromatic hydrocarbons,combining with the physical and chemical properties to determine the atmospheric pollution of Liuzhou. The results show that the concentrations of ΣPAHs in the air of Liugang and Shuangchong village are 519. 44,541. 45 ng·d - 1,with an order of 2 - 3 ring > 4 ring > 5 - 6 ring. In rainfall they were 581. 88,756. 09 ng·m - 2·d - 1,and the order is 4 ring > 2 - 3 ring > 5 - 6 ring,in dustfall were 735. 86,1 558. 51 ng·g - 1·d - 1,and the order is 4 ring > 5 - 6 ring > 2 - 3 ring. It is confirmed that the PAHs in atmosphere of Liuzhou come from coal burning by heavy industry enterprises and pollution is serious.关键词
