| 摘 要： | 对采集的个旧与兰坪矿区不同的土壤上生长的3科7个种植物及相应的土样Cd含量进行了分析。结果表明,矿区各区域的土壤都受到不同程度的Cd污染,但不同区域受污染的程度不一;不同植物体内Cd含量差异显著,其中以蓖麻含Cd量最高,其次为水杨梅,两者Cd含量基本达到Cd超富集植物含Cd量,具有Cd污染土壤植物修复的潜力;除水杨梅外,其余植物地上部分Cd含量均低于地下部分Cd含量。说明矿区及尾矿上生长的植物并非都具有超富集能力,但均具有较强的重金属污染耐性。

| Abstract: | The Cd concentration in 7 species of plants(belong to 3 families) collected in Gejiu and Lanping mine areas and tailings in Yunnan,as well as the corresponding soil samples,were analyzed.The results showed that all mine soils were polluted by Cd,but the pollution degrees were different in varied mining areas.The concentrations of Cd in different plants were significantly different.And the highest concentration of Cd was found in Ricinus communis L.,which followed by Adubarubella Hance And the Cd concentrati... |
