摘要
随着经济的快速发展,海洋重金属污染日渐严重,贝类由于其分布广,活动性低,且对重金属具有高积累性和强耐受性,是海洋环境中受污染程度较高的生物之一。笔者将从贝类重金属富集特征以及影响贝类重金属富集因素两方面对有关贝类重金属的研究现状进行综述,概括了贝类种间、个体间以及组织间对重金属的富集特征,重点分析了重金属因素(种类、形态、浓度等)和环境因素(季节、温度、盐度等)对贝类富集重金属的影响,以期为有关贝类重金属方面的研究提供参考。
In recent years,heavy metal pollution of the marine environment is becoming increasingly serious.Shellfish,due to its wide distribution,low mobility,and high accumulation and strong tolerance to heavy metals,are one of the organisms with high degree of pollution in marine environment.This paper reviewed the research status of heavy metals in shellfish from two aspects:enrichment characteristics and influencing factors.The enrichment characteristics of heavy metals in shellfish,individuals and tissues were summarized,the influence of heavy metal factors(species,forms,concentrations,etc.)and environmental factors(season,temperature,salinity,etc.)on bioaccumulation of heavy metals in shellfish were analyzed to provide reference for the study of heavy metals in shellfish.
