摘    要:研究了北京市交通路口大气颗粒物中非烃类化合物的污染特征。通过对2000年6月采集的大气颗粒物样品的分析,研究了北京市崇文门路口大气颗粒物中非烃类化合物的污染状况。结果表明:交通排放是大气颗粒物中非烃类化合物的重要来源之一;总体上非烃类化合物主要富集在粒径较小的粒子中,细粒子中的非烃类化合物应主要来源于机动车尾气排放;白天ρ(非烃类化合物)随机动车流量的增加而增加,夜晚机动车流量减小,但ρ(非烃类化合物)却高于白天,显示出大型柴油车的主要影响和贡献;非烃类化合物的污染主要表现为酞酸酯和苯酚类化合物的污染。并对交通路口大气颗粒物中酞酸酯的来源进行了探讨。

关 键 词:大气颗粒物  非烃类化合物  酞酸酯  污染特征  交通路口  北京市

Abstract:The pollution of non-hydrocarbons at the Chongwenmen crossing was studied through the analysis of particulates in the air sampled in June 2000. The results showed that the traffic source was one of the major sources of non-hydrocarbons in the particulates. Non-hydrocarbons were mainly in the particulates of small size. The vehicle emission was the main source of non-hydrocarbons in the fine particulates. The mass concentration of non-hydrocarbons went up with the increase of the flux of vehicles in the daytime. At night the flux of vehicles was less, but the mass concentration of non-hydrocarbons was higher than that in the daytime because of the main influence of the emission of diesel vehicles. The pollution of non-hydrocarbons was the main pollution of phthalidyl and phenol compounds. The sources of phthalidyl in the particulates at the traffic crossing were also studied.
Keywords:particulates  non-hydrocarbons  phthalidyl  pollution property  traffic crossing  Beijing
