1蔬菜中铅镉铜锌含量的影响因素研究显示文摘用通过大田调查的方法,研究了影响蔬菜中Pb、Cd、Cu、Zn含量的因素。结果表明:(1)蔬菜对Pb、Cd、Cu、Zn的富集可分为高富集、中富集和低富集,针对不同的土壤污染程度,可以选择不同富集系数的蔬菜种植;(2)提高土壤pH值,有助于降低蔬菜中Pb、Cd、Cu、Zn的含量;调节土壤阳离子交换量、有机质含量和粘粒含量应注意适度,过高会导致相反的结果;(3)土壤Pb、Cd、Cu、Zn之间的相互关系较为复杂,Cu与Zn之间具有相互的拮抗作用,Cu对Pb的吸收具有促进作用。祖艳群 李元 陈海燕 陈建军 Marianne Guhur Christian Schvartz 2003农业环境科学学报2003,22,3:94
2昆明市蔬菜及其土壤中铅、镉、铜和锌含量水平及污染评价显示文摘对昆明市蔬菜及其土壤中铅、镉、铜和锌含量水平进行了初步的调查并对其土壤污染进行了评价 ,结果表明 :蔬菜土壤重金属Pb、Cd、Cu、Zn均存在一定程度的污染 ,其中Pb、Zn为轻污染 ,Cd、Cu为中污染 ,土壤重金属综合评价为中污染。蔬菜可食部分Pb、Cd、Zn的含量均超过国家食品卫生标准和绿色蔬菜标准 ,依次为Pb、Cu、Cd、Zn。祖艳群 李元 陈海燕 陈建军 Marianne Guhur Christian Schvartz 2003云南环境科学2003,22,B03:55
3蔬菜及土壤的铅、镉、铜和锌污染及评价方法初探显示文摘通过大田调查的方法,应用聚类分析和综合污染指数法,对云南省昆明市蔬菜及其土壤中Pb,Cd,Cu和Zn污染进行了评价。结果表明:(1)土壤重金属Pb,Cd,Cu,Zn的超标率依次为:Cd>Cu>Zn>Pb.综合污染指数:Cd和Cu为中污染,Pb和Zn为轻污染。蔬菜土壤重金属总的综合评价为中污染。聚类分析结果为菜豆、番茄和青花菜的土壤污染较严重。(2)蔬菜Pb,Cd,Cu,Zn的含量超标率依次为:Pb>Cu>Cd>Zn.聚类分析表明:萝卜、菜豆和番茄污染较严重。(3)聚类分析与污染指数评价具有一致性、可比性,结合两种方法进行分析评价更加合理、科学。祖旭宇 李元 Christian Schvartz 2004云南农业大学学报2004,19,4:14
4Factors affecting trace element content in periurban market garden subsoil in Yunnan Province,China显示文摘Field investigations were conducted to measure subsoil trace element content and factors influencing content in an intensive periurban market garden in Chenggong County,Yunnan Province,South-West China.The area was divided into three different geomorphological units:specifically,mountain (M),transition (T) and lacustrine (L).Mean trace element content in subsoil were determined for Pb (58.2 mg/kg),Cd (0.89 mg/kg),Cu (129.2 mg/kg),and Zn (97.0 mg/kg).Strong significant relationships between trace element content in topsoil and subsoil were observed.Both Pb and Zn were accumulated in topsoil (RTS (ratio of mean trace element in topsoil to subsoil) of Pb and Zn 1.0) and Cd and Cu in subsoil (RTS of Cd and Cu 1.0).Subsoil trace element content was related to relief,stoniness,soil color,clay content,and cation exchange capacity.Except for 7.5 YR (yellow-red) color,trace element content increased with color intensity from brown to reddish brown.Significant positive relationships were observed between Fe content and that of Pb and Cu.Trace element content in mountain unit subsoil was higher than in transition and lacustrine units (M > T > L),except for Cu (T > M > L).Mean trace element content in calcareous subsoil was higher than in sandstone and shale.Mean trace element content in clay texture subsoil was higher than in sandy and sandy loam subsoil,and higher Cu and Zn content in subsoil with few mottles.It is possible to model Pb,Cd,Cu,and Zn distribution in subsoil physico-chemical characteristics to help improve agricultural practice.Yanqun zu Laurent Bock Christian Schvartz Gilles Colinet Yuan Li 2011Journal of Environmental Sciences2011,23,3:3
