环境化学条件对水体沉积物中重金属释放影响的研究述评

环境化学条件是影响水体沉积物中重金属释放的主要因素。根据国内外对该课题的研究成果,本文主要就盐度、酸度、氧化还原、温度以及有机络合剂等化学条件变化对重金属释放的影响分别进行了研究述评,对存在问题作了分析讨论,以期为今后该课题的研究提供参考。

A Survey of the Heavy Metal Release from Aquatic Sediments Affected by the Aquolie-Chemical Conditions

Aquolie-chemical condition is the main factor to affect heavy metal release from sediments. On the basis of the studies on the subject at home and abroad, effects of the chemical factors, such as saltwater/sediment interactions, changes of water acidity, redox, temperature as well as organic com- plexing agents are reviewed respectively. Some problems existing or to be solved in these studies have also been analysed and discussed. It is expected that the review could give a reference to the further study on the subject.
