- 摘要:
- 以小羽藓和柏状灰藓为试材，采用电感耦合等离子体质谱法研究了镉、铅、镍和铜在小羽藓和柏状灰藓体内的含量，设置4种重金属共3个浓度梯度，分别为0.2、0.4、0.8 mmol?L-1，采用正交设计设置9种不同浓度的复合试验，以蒸馏水处理为对照，对苔藓进行7 d的不同浓度的单一金属和复合金属胁迫处理，以期研究小羽藓和柏状灰藓对重金属的富集能力。结果表明：在单一金属胁迫下，苔藓体内相应的重金属含量迅速增加，复合金属胁迫后的苔藓，各重金属含量均明显高于对照。2种苔藓对4种重金属都具有很强的富集能力。小羽藓和柏状灰藓适合作为重金属污染的净化植物。
- Abstract:
- In order to study enrichment ability for heavy metals, Haplocladium capillatum and Hypnum cupressiforme were used as test materials.The contents of four chemical elements，namely，cadmium(Cd)，nickel(Ni)，lead(Pb) and copper(Cu)were analyzed by means of CP-MS analysis method.0.2 mmol?L-1,0.4 mmol?L-1,0.8 mmol?L-1 of three concentration gradient were set up respectively，according to the orthogonal experimental design of nine different concentrations of mixed group，with distilled water treatment for comparison，the mosses were treated with stresses for seven days using different concentrations of single metals and complex metals.The results showed that heavy metal contents were significantly greater than the control group, Haplocladium capillatum and Hypnum cupressiforme had the very strong enrichment ability to heavy metal.It was suggested that the moss Haplocladium capillatum and Hypnum cupressiforme could be used as purification plants for the heavy metals polution.
