摘要
通过对烟尘、汽车尾气排放颗粒物、尘土中的有机质经提取分离得饱和烃、芳香烃、菲烃、沥青四个馏分。四个溜分的相对含量有一定的差异性。并将其饱和烃、芳香烃 ,经 GC-MS分析 ,其特征明显不同。这种特征的不同可算得大气颗粒物中有机污染的来源。
Samples of dust, particulates of exhaustgas, dust were collected after extraction and separation, four kinds of componrnts, such saturated hydrocarhons, aromations, comonents such as saturated hydrocarbons Aromatics, non hydrocarbons and asphaltenes, were obtained The kinds of concentration are different Saturated hydrocarbons, aromatics were determined by GC MS, thecharacteristics are different The characteristcrs can be used tracing the sources of organic
