摘    要:对北京首钢地区大气颗粒物中有机物浓度、族组成及其饱和烃、多环芳烃的组成和分布特征进行了研究.在大气颗粒物中共检测出40多种多环芳烃,其中属于美国国家环保局(EPA)优先控制污染物9种,且大多具有致癌和致突变性.根据生标特征,有机污染物主要来源于煤的不完全燃烧,部分来源于汽车尾气的排放.燃煤对首钢地区造成的污染更为严重.

关 键 词:大气颗粒物  有机物  饱和烃  多环芳烃  有机污染物    不完全燃烧  北京  首钢地区

Abstract:This paper analyzes the concentrations of organic matter, the group components, the compositions and distribution of aliphatics and polycyclic aromatic hydrocarbons (PAHs) from the atmospheric particulates in the Shougang district, Beijing. More than 40 kinds of PAHs from the atmospheric particulates have been detected, nine of which are precedence-controlled pollutants set by US EPA. Many PAHs are carcinogenic and mutated. According to the biomarkers, the organic pollutants come mainly from the incomplete combustion of coal, partly from the emission of automobile wastes. The coal can result in more grave pollution in the Shougang district than the petroleum during the incomplete combustion.
Keywords:atmospheric particulate  organic pollutant  polycyclic aromatic hydrocarbons (PAHs)  precedence-controlled pollutants of EPA  Shougang district  Beijing
