ng·g-1,平均浓度为1.678 ng·g-1.OCPs平均浓度顺序如下:DDTs＞HCHs＞氯丹类＞硫丹类,DDTs类农药的检出率最高,DDTs和HCHs是土壤中OCPs主要的组成成分,研究区土壤中DDTs和HCHs的残留水平低于国内其他地区土壤中含量,也低于规定的土壤阈值和土壤环境质量标准,本研究区土壤未受OCPs的污染.β-HCH和p,p'-DDE分别是HCHs和DDTs的主要组成成分.研究区土壤中OCPs主要来源于历史残留,无新的污染源输入.土壤中TOC和pH值对OCPs的残留存在影响,并且呈现弱的负相关性,不同类型土壤OCPs残留量存在差异,OCPs在树林土壤中的残留含量高于海岸带和原耕地土壤中.风险评价表明研究区土壤中HCHs农药残留量不会对生物产生风险;DDTs类农药对研究区生物存在可能性较小的生态风险,危害性总体较低.","authors":[{"authorName":"<span
