摘要

摘要: 通过在冬夏两季对广州市海珠区表层土壤和空气样品中有机氯农药的采样和分析，对有机氯农药残留现状和潜在生态风险进行了研究。结果表明，土壤中六六六类（HCHs）含量水平在2007年冬季和2008年夏季分别为0.57～8.77 ng/g和0.30～14.9 ng/g，平均值分别为2.87 ng/g和3.04 ng/g，都未超过国家土壤环境质量标准的一级自然背景值。冬季和夏季滴滴涕类（DDTs）含量水平分别为3.69 ～697.7 ng/g和0.88～263.3 ng/g，平均值分别为85.5 ng/g和39.4 ng/g。海珠区部分地点DDTs超过国家土壤环境质量标准的一级自然背景值。DDTs为该区域表层土壤中主要的有机氯农药残留。在研究区域对逸度模型进行了初步应用。

Abstract: Surface soil and air samples collected from Haizhu District of Guangzhou City were analysed for organochlorine pesticides (OCPs). The status of OCPs residues and the potential ecological risk were studied. The results showed that the concentration of total HCHs in surface soils in 2007 winter and in 2008 summer ranged from 0.57 to 8.77 ng/g and 0.30 to 14.9 ng/g with the averages of 2.87 ng/g and 3.04 ng/g respectively. Both HCHs and DDTs did not exceed the National Soil Quality Standard Level Ⅰ (natural background level). The concentration of DDTs in the surface soils in winter and summer ranged from 3.69 to 697.7 ng/g and 0.88 to 263.3 ng/g, with the average of 85.5 ng/g and 39.4 ng/g respectively. The concentration of DDTs in several samples exceeded the National Soil Quality Standard Level Ⅰ. DDTs are the main OCPs residues in the surface soils in the study district. Fugacity model has been preliminarily applied in the study area.
