摘要
重金属进入土壤 -植物系统后 ,会在土壤中累积 ,并通过食物链的富集、传递 ,危害人体健康。介绍了影响土壤中重金属进入植物体的不同因素 ,如 :土壤特性 (pH值、可交换阳离子容量等 )、有机物、根际分泌物及多种重金属离子共存时复合污染等 ;另外还介绍了重金属复合污染的几种评价指数等方面的最新研究进展。
This paper reviewed the recent development in the field of heavy metal studies, focusing on the different factors affecting heavy metals uptaking, e.g., soil characteristics (pH, cation exchange capacity), organic matters, root exudates, and combined pollution of multiple heavy metals. Index of risk assessment of the combined pollution in the soil-plant system was also discussed.
