摘    要:通过对湖州地区74个土壤样品多环芳烃含量的测定,分析了湖州市不同土地利用类型土壤中多环芳烃(PAHs)的含量特征及污染水平。结果表明,湖州地区PAHs各组分的含量均有检出,各种土地利用类型表层土壤均受到一定程度的PAHs污染,但均小于荷兰土壤修复标准;湖州市区耕地中PAHs的含量最高;从PAHs低环/高环比值小于1以及芘/苯并(a)芘比值小于2,反映了湖州地区土壤中PAHs主要是由燃煤和生活污染产生的。

关 键 词:土壤  多环芳烃  土地利用类型  湖州

Abstract:A total of 74 surface soil samples were collected and analyzed for polycyclic aromatic hydrocarbons(PAHs) and the contents and pollution levels of 15 PAH compounds in different types of surface soils of Huzhou were studied.Results show that the highest content of PAHs could be found in Huzhou urban.The ratio of low circle PAHs/high circle PAHs were less than 1,and the ratio of pyrene/benzo(a)pyrene were less than 2.This means that the PAHs pollution in Huzhou soils was mainly from the burning coal and domestic pollution.
Keywords:scanning electron microscope  suspended particulates  water environment  energy dispersive X-ray  microanalysis
