酸雨地区蔬菜对重金属的吸收及重金属健康风险基准的估算

Shuitu Baochi Xuebao, 2008
通过盆栽实验,以小白菜(上海青)、大白菜和萝卜为指示作物,研究了酸雨作用下Cu,Zn,Pb,Cd,Cr和Ni复合污染物在土壤-作物系统中的吸收与富集情况。结果表明,酸雨-重金属复合污染处理使Cu,Pb,Cr和Ni在蔬菜中积累量明显高于对照处理;Zn和Cd一般只有在复合污染处理中外源Zn或Cd含量较高时才明显高于对照处理。与对照相比,酸雨-重金属复合污染处理使Pb和Ni的富集系数增大,Cu的富集系数多数情况下增大,Cd的富集系数多数情况下减小,Zn和Cr富集系数的变化在不同蔬菜之间存在较明显的差异 ...

重庆市主城区街道地表物中重金属的污染特征

Shuitu Baochi Xuebao, 2006
分析了重庆市主城区街道地表物的基本性质及As、Cd、Cr、Cu、Hg，Ni、Pb，Zn等元索的全置、模拟酸雨（pH4．5）的浸出量。结果表明：各功能区中街道地表物的自然组成均以中等粒径的为主；就元素而言，粒径越细对重金属的贡献率越高；就功能区而言．细粒径与中等粒径的颗粒对重金属贡献率较为接近。街道地表物呈碱性，有潜在的有机物污染。重庆市主城区街道地表物重金属元素含量有较大的差异，受人为活动干扰严重的重金属种类为Cr、Cd、Hg、Cu。内梅罗指数评价结果显示除Ni外，其他元素均有不同程度的污染 ...
