摘要
对珠江三角洲某乡镇的城区及三个乡村气溶胶有机物的测定,发现:正烷烃类有机物高分子部分具有明显分不开的鼓包,污染较为明显;所有样品均含有多种美国环保局(EPA)公布的优先控制的多环芳烃(PAHs),并均含有机动车尾气排放的标志化合物烷基苯(M/Z91,92)和塑料增塑剂等来源的邻苯二甲酸酯类(M/Z149)。表明该镇各区域均已明显受到机动车尾气排放和工业废气排放的污染。
The aliphatic and aromatic fraction of lipids of aerosol samples which were collected from some town and its suburb of Pearl River delta was tested. Preliminary data show that the UCM hump was found on TIC of GC - MS of alkanes of all samples. All samples contain 11 to 15 priority PAHs (US. EPA) with 4 - ring predominating, alky - benzens and ph-thalate esters. These results indicate that the organic pollutants of aerosol mainly come from combustion products of fossil fuels including vehicle exhaust and industrial emission in this area.
