摘    要:对常州市某典型化工园区大气中挥发性有机物(VOCs)污染状况进行了调查。结果表明,该化工园区大气中检出挥发性有机物共有58种,组分有芳香烃、饱和烷烃、卤代烃、烯烃、醛酯类化合物及其他类;苯、甲苯、乙苯、二甲苯为主要挥发性有机污染物,质量浓度为1.0~194μg/m~3;均未超出参考标准的限值。背景点位和园区点位大气中主要ρ总(VOCs)在秋冬季最高,敏感点大气VOCs随季节变化也较为明显;园区T1和T2ρ总(VOCs)年均值高于敏感点位,背景点位年均值最低;园区点位除了汽车尾气排放之外,溶剂的挥发和生产工艺中污染物的排放也增加了大气中苯系物的浓度,同时也对敏感点位和对照点位的大气质量产生了一定的影响。

关 键 词:挥发性有机物  化工园区  环境空气  常州

Abstract:This paper reported the composition and distribution of volatile organic compounds ( VOCs) in the ambient air of some typical chemical industrial park in Changzhou.The results showed that 58 VOCs were detected in the air of this chemical industrial park,including aromatic hydrocarbons,saturated hydrocarbons,halogenated hydrocarbons,olefins,aldehyde and ester compounds,et al.The main pollutants of VOCs were benzene,toluene,ethylbenzene,and xylene,the mass concentrations of which were in the range of 1.0~194 μg/m3 .None of them were out of the limit values in reference standards.The total mass concentrations of the main VOCs at background and park sites were highest in autumn and winter,and the atmospheric VOCs of sensitive sites changed greatly with the seasonal variation.The annual average total concentrations of the main VOCs in park T1 and T2 were higher than those of sensitive sites,which were the lowest at background site.Besides the vehicle exhaust emission,the solvent volatilization and the pol-lutant emission in the production process increased the concentration of benzene series in atmosphere,at the same time the atmos-pheric quality at sensitive and background sites was affected.
Keywords:Volatile organic compounds  Chemical industrial park  Ambient air  Changzhou
