| 摘 要： | 植物效应为重金属的生物有效性评价提供了链接,本文就污染土壤中重金属生物有效性问题,探讨了植物效应和生物有效性的关联关系。阐述各种植物效应在重金属生物有效性评价、监测及应用领域的研究进展,探讨了目前存在的某些不足。根据重金属的生物有效性评价结论,可针对不同土壤污染类型采用不同的植物应对措施,如可以尝试应用避性排斥型植物在生物有效性低的污染土壤上生产出非污染的农产品,为进行安全农业生产提出了一条新的思路。

| Abstract: | There are links between the effect of plant and the evaluation for bioavailability of heavy metals.In this paper the problem of bioavailability of heavy metals in polluted soil is reviewed and the correlation between the effects of plant and bioavailability are explained.At the same time,the applications of plant effects on the measuring and monitoring method of bioavailability are introduced in detail and some existing disadvantages are discussed.Consequently,measures with different plants can be taken to ... |
