【摘要】 对舟山群岛新区食用农产品产地土壤中的p H值、总镉、总汞、总砷、总铅、总铬、总铜、六六六、滴滴涕及选择控制项目总锌和总镍的含量进行了测定,以国家环境标准《食用农产品产地环境质量评价标准》(HJ0332-2006)中土壤环境质量标准值为依据,采用单因子污染指数法和综合污染指数法评价了土壤环境质量。结果显示,各单项指标均低于食用农产品产地要求的土壤质量标准限值,说明舟山群岛新区食用农产品产地土壤质量安全。但普陀横街社区及岱西林家村共三个采样点的重金属镉超标,存在污染风险,需要引起重视。污染指数评价结果显示:十项监测项目的单因子污染指数均小于1.0,表明土壤尚未未受到污染;综合污染指数为0.80,说明新区食用农产品产地尚处于安全水平,但已经处于警戒线,存在污染风险,尤其是普陀横街社区产地的综合污染指数值为1.94,已经处于轻度污染状态。更多还原

【Abstract】 The contents of Cd, Hg, As, Pb, Cr, Cu, HCHs, DDTs and Zn, Ni in surface soil of edible agricultural products origin in Zhoushan Archipelago New Area were analyzed. The soil environmental quality was evaluated with single factor index and comprehensive pollution index based on standard such as HJ 0332-2006. The results showed that the contents of Cd, Hg, As, Pb, Cr, Cu, HCHs, DDTs and Zn,Ni were all under the limit values prescribed by national standard(HJ 0332-2006). It showed that the soil environmental quality was safe. But the content of Cd in Putuo and Daixi area was more than the standard limit value, so there is the risk of contamination. Single factor indexes of pollution factors were lower than1.0, which showed that the soils were not polluted. Comprehensive pollution index of pollution factors is0.80, it’s mean that the soil pollution degree reached guard line. Especially the Putuo area, the comprehensive pollution index is 1.94, that’s meant this area is in a mild degree of pollution status.更多还原
