| 摘 要： | 以潼关县黄金生产区及附近菊科植物(金盏银盘、叉枝蒿和白蒿)为研究对象,采用火焰原子吸收光谱法对其铜、镉和锌等重金属含量进行了测定,以便确定建立人工生态系统的植物种类。结果表明:在3种植物中,金盏银盘的根对Cu的吸收效果最好,其值为98.58mg/kg,叶片对Zn的吸收效果较好,茎对Cd的吸收效果最好,且金盏银盘地上部分对Cd的富集能力达到405.9mg/kg。

| Abstract: | Taking 3 Compositae plants:Bidentis bipinnate,Artemisia divaricata and Artimisiae sieversianae around the gold area as test materials,the contents of the heavy metals such as Cu,Cd and Zn were determined.The results showed that the root of Bidentis bipinnate had the highest contents of Cu and it was 98.58 mg/kg,and the leave of Bidentis bipinnate had the highest contents of Zn,and stalk of Bidentis bipinnate had the highest contents of Cd.Overground part of Bidentis bipinnate had a strong absorptive capacity for Cd,and it was 405.9 mg/kg. |
