| 摘 要： | 用吸附/热脱附-GC/MS方法研究了茂名市大气中的VOCs。结果表明，茂名市大气中检测出130多种VOCs，其主要成分是烷烃、芳 烃、烯烃和卤代烃，其中14种是有毒污染物。环烷烃是茂名炼油厂排入大气的特征VOCs。大气中浓度最高的VOCs是正己烷、1，2，4-三甲 苯、溴仿、苯、甲苯。河东区大气中VOCs总浓度比河西区高。VOCs主要来源于石油化工企业机动车尾气和茂名炼油厂。

| Abstract: | The volatile organic compounds (VOCs) in the ambient air in Maoming have been researched with the method of sorption/thermal desorption\|GC/MS.The results show that 130 or more VOCs exists in Maoming,most of which are alkane,aromatic hydrocarbon,alkene and halohydrocarbon,and 14 of which are hazardous.The characteristic VOCs emitted from Maoming Oil Refinery are cycloparaffinic hydrocarbons.Hexane,1,2,4\|trimethylbenzene,tribromomethane,benzene,and toluene have the highest contents in the air.The content of the total VOCs in the ambient air in Hedong District is higher than that in Hexi District.The main sources of VOCs may be the oil chemical plants,vehicle exhaust and Maoming Refinery. |
