土壤重金属污染及对生物体影响的研究进展

重金属污染是当今社会世界性的环境生态问题。由于人类社会城市化进程加剧、工业生产中"三废"的不合理排放以及现代农业中各种农药化肥的大量使用,导致土壤中重金属的含量剧增,污染问题严重,其中尤以重金属镉、汞、铅等在生物体内的富集与抗生性的研究日益受到关注。笔者综述了土壤重金属污染及对生物体影响的研究进展,以期为土壤重金属综合治理与污染修复提供科学依据。

Heavy Metal Contamination and Its Effect on Organism in Soil: A Review

Heavy metals pollution is a worldwide problem in the environment and ecological system. Due to increasing urbanization of human society, unreasonable emission of the "three wastes" from industrial production and using all kinds of pesticide and fertilizer in modern agriculture, the content of heavy metals in soil is seriously the pollution. Especially, the research of the heavy metals cadmium, mercury, lead enrichment in organism body and and antibiosis has attracted more and more attention at the present. This review focuses on the heavy metal contamination and effects on organism in soil, as the above concluded, in the future it should provide the scientific basis for the comprehensive management and remediation on soil of heavy metal pollution.
