镉和酸化对水生动物的毒害及生理生态的影响

Toxic Effects of Cadmium and Acidification on Aquatic Animals and Their Eco-physiological Responses

研究表明酸化和镉单独处理会对水生动物的生长发育产生影响。由于人类活动,一些沿海和河口中的镉含量不断升高,严重影响了水生动物的代谢。目前,关于镉对水生动物的影响已有报道,与此同时,水体酸化与水体重金属含量增加可能同步发生。为了更加全面地预测水生动物对水体重金属变化的生理生化应答,越来越多的学者开始致力于研究酸化和重金属的复合胁迫对水生动物的交互影响。为此,本文从镉对水生动物的影响以及酸化与镉对水生动物的协同效应等几个方面综述了酸化和镉胁迫对水生动物毒害、生理生态影响的研究进展,以期为今后的水体酸化研究提供参考。

Studies have shown that acidification and cadmium treatment alone will affect the growth and de-velopment of aquatic animals.Due to human activities,the content of cadmium in surface water and ground-water is increasing,which seriously affects the metabolism of aquatic animals.At present,the effects of cad-mium on aquatic animals have been reported.It is also shown that the acidification of water bodies may oc-cur simultaneously with increasing heavy metal content.To more accurately predict the physiological and biochemical responses of aquatic animals to heavy metal changes,more and more studies on the interaction between acidification and heavy metal stress on aquatic animals have been performed.Herein,the effects of acidification and cadmium stress on aquatic animals and their eco-physiological responses were reviewed,in the hope of providing references for water acidification research in the future.
