摘要
为掌握廊坊市挥发性有机物(VOCs)的污染特征和来源,探究臭氧生成原因,开展廊坊市环境样品的采样和分析测量工作,进行VOCs来源解析,定量分析VOCs在O3二次生成中的作用,对廊坊市区和重点工业区大气VOCs浓度水平和化学组成进行测定、进行VOCs活性评估,总结出不同区域的不同活性的VOCs典型成份,开发区和药材公司VOCs贡献排名前三的物种均为间/对-二甲苯、异戊二烯和乙烯,且顺序相同,这三种物种贡献分别占开发区和药材公司所有测量VOCs的37.2%和34.9%。霸州VOCs贡献较高的物种是间/对-二甲苯、1,2,4-三甲基苯和乙烯;香河VOCs贡献排名前三的物种均为芳香烃,分别为间/对-二甲苯、甲苯和邻二甲苯。
In order to get the sources and pollutionalcharacteristics of volatile organic compounds(VOCs)ofLangfang City,study the generation mechanism of ozone,the environmental sampling and source apportionmentof VOCs was carried out in Langfang City.In this paper,the role of VOCs in the formation of ozone,the chemical composition and the active ingredient of VOCs was studied in different administrative division of Langfang.There have three results:(1)the top three VOCs of both Kaifa county and medicine company were m/f-xylene,isoprene and ethylene,and they respective accounted for37.2%and34.9%of the total VOCs to Kaifa county and medicine company;(2)the top three VOCs of Bazhou City were m/f-xylene,1,2,4-three methyl benzene and ethylene;(3)all the top three VOCs of Xianghe City were aromatic hydrocarbon,they were m/f-xylene,toluene and o-xylene respectively.
