| 摘 要： | 本文通过区域布点法对兰州市西固区的主要工业区进行空气降尘采样,利用色谱质谱分析仪对大气降尘中的芳烃类有机污染物进行了分析,结果揭示出兰州市西固区芳烃类有机污染物中邻苯二甲酸脂类(PAEs)占主导地位,其中又以邻苯二甲酸二丁酯(DBP)和邻苯二甲酸二酯(2-乙基己基)(DEHP)占芳烃总含量的比重较大。通过样品的对比分析和来源解析,指出兰州市西固区大气降尘中的芳烃类有机污染物来源与西固区A公司的废气排放有关,应加强对大气环境的保护和限制工厂废气直接向大气中排放。

| Abstract: | Analyzing the aromatic organic pollutants of the samples from the Xigu District of Lanzhou City by GC-MS,the authors found out that the phthalates occupy the prominent position in the whole pollutants.Among the aromatic hydrocarbons,DBP and DEHP are highest.Through comparative analyses of samples and sources,it is pointed out that organic pollutants such as aromatic hydrocarbons in atmospheric dust fall in the Xigu Districit of Lanzhou City is closely related to the emission of waste gases by Company A in the Xigu District.Therefore,it is necessary to intensify the protection of atmospheric environment and impose instructions on the direct emission of waste gases by factories or plants into atmosphere. |
