| 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 |

| 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 |
| 4 | Factors 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 | 2011 | Journal of Environmental Sciences2011，23，3： | 3 |

| 13 | Relationship between heavy metal concentrations of herbaceous plants and soils at four Pb-Zn mining sites in Yunnan,China显示文摘This paper studied the relationship between heavy metal concentrations of herbaceous plants and soils at four Pb-Zn mining sites in Yunnan,China.50 herbaceous plant samples of 9 plant species from 4 families and 50 soil samples were collected and then ana1yzed for the tota1 concentrations of Pb,Cd,and Zn.The results showed that the average concentrations of Pb,Cd,and Zn in soil samples were 3772.83,168.81,and 5385.65 mg/kg,respectively.The average concentrations of Pb,Cd,and Zn were 395.68,28.14,and 1664.20 mg/kg in the shoots,and 924.12,57.25,and 1778.75 mg/kg in the roots,respectively.Heterospecific plants at the same site and conspecific plants at various sites had different average levels of Pb,Cd,and Zn,both in the shoots and the roots.Enrichment coefficients of Pb,Cd,and Zn were greater than 1 in 2,3,and 9 herbaceous plant samples,respectively.Translocation factors of Pb,Cd,and Zn were greater than 1 in 10,17,and 25 herbaceous plant samples,respectively.In all 50 samples,the concentrations of Pb,Cd,and Zn between the shoots and the roots,the shoots,and the soils,and the roots and the soils had significant positive relationships. | Yuan LI Yanqun ZU Qixian FANG Zhaohua GAO Christian SCHVARTZ | 2009 | Frontiers of Environmental Science & Engineering2009，3，3： | 0 |
