以上海市延安高架、中环和外环3条主要道路的交通繁忙地带绿地土壤为研究对象,调查研究了其多环芳烃(PAHs)的分布状况.结果表明,3条道路绿地土壤中∑16PAHs的含量在538 ～ 2.19×10~4 μg/kg之间,与国外Maliszewska-Kordybach建立的标准相比,3条道路绿地土壤均受到PAHs的污染,尤其是4 ～ 6环PAHs,其含量占∑16PAHs的90%,分析认为有机质是影响其分布的重要因素之一.3条道路污染程度有所不同,大小顺序为:外环＞延安高架＞中环,这主要与道路建成年限和允许的通车车辆类型有关,通车年限越长,大型卡车越多,土壤所受PAHs污染的程度越严重.

Distribution characteristics of PAHs in the green-belt soils collected from Yan'an Road Viaduct, the Middle Ring Road and the Outer Ring Road in Shanghai were studied in the paper. Results showed that the total content of 16 kinds of PAHs in soils ranged from 538 μg/kg to 21932.8 μg/kg, which were already contaminated with PAHs if judged by the corresponding standards from Poland, Canada and other countries, in which 4-6 ring PAHs accounted for about 90% of the total PAHs. Moreover, the varying pollution degree of PAHs indicated that the road age and heavy vehicles using diesel contributed mainly to PAHs contamination. Correlation analysis indicated that soil organic matter was a main influential factor of PAHs distribution in the soils.
