| 摘 要： | 潮间带是一个典型的环境脆弱带和敏感带,极易受到人类活动的破坏.潮间带重金属除了直接对潮间带生物有影响外,还可以通过过食物链的富集和放大作用影响人类健康,同时由于潮间带水动力和生物活动的影响,造成重金属的重新分布和释放,产生重金属的"二次污染",直接危害近岸环境.开展重金属元素在潮间带沉积物中含量、赋存形态、污染评价及其生物有效性已成为目前环境科学领域中十分重要的研究内容和任务,国内外学者均对河流沉积物重金属污染开展了大量的研究.文章从这4个方面阐述了潮间带沉积物重金属研究进展,以期为潮间带沉积物重金属研究提供一定的参考.

| Abstract: | Intertidal zone is a typical environmental vulnerability zone and sensitive belt, It is vulnerable to destruction by human activities. Intertidal zone of heavy metals directly have an affect on intertidal zone biological,and through enrichment and amplification of the food chain affect human health, meanwhile because of the influence that intertidal zone hydrodynamic and biological activities cause to heavy metal, s redistribution and release, heavy metal, s secondary pollution harm to offshore environment directly. It is a very important task to develop the study of heavy metal content and geometrical shape and pollution evaluation and bioavailability of sediments in intertidal zone of the current environment science field.Domestic and foreign scholars have developed a lot of research about heavy metal pollution of fluvial sediments.This article reviewed intertidal zone sediments from the four aspects, in order to provide some reference about heavy metal of sediments in intertidal zone. |
