环境重金属污染水体及土壤的生态毒理诊断及修复研究进展

Toxicity assessment and bioremediation of heavy metal polluted water and soil

针对环境重金属污染水体及土壤的生态毒理诊断及修复研究进展进行综述,指出利用高等植物萌发毒理试验评价环境重金属污染的生态毒害,较客观地反映了污染物的毒害水平,生态毒理诊断较测定重金属总量更科学,具有简单、易操作的优点,还指出重金属的植物修复技术具有投资少、效率高、不破坏土壤结构、不产生二次污染等特点,有着广泛的应用前景。

The toxicity assessment and bioremediation of water and soil polluted by heavy metals in the environment is reviewed. The application of seed germination test of higher plants to assess the ecotoxicology of heavy metal contaminant can reflect the pollution level,and it is a simpler method than the total heavy metal assessment. Heavy metal phytoextraction is a soil remediation technique with broad perspective, less investment, higher efficiency and without destroying soil structure and re-pollution.
