我国贝类重金属污染现状及其脱除技术研究进展

随着我国工业和经济的不断发展,水体中重金属污染已成为我国重要的环境问题之一。贝类由于其滤食性特点具有极强的重金属富集能力,对我国贝类产品的质量安全造成了潜在风险,也给我国的贝类产品的进出口造成贸易壁垒。因此,有效控制贝类重金属污染已成为亟待解决的重大问题。本文综述了我国贝类重金属的污染现状,介绍了贝类重金属脱除技术的2个方向,即贝类活体脱除技术和贝类水解液脱除技术。最后对贝类重金属脱除技术仍存在的问题进行归纳和总结,为贝类重金属脱除技术的研究工作提供一定参考。

Research progress of heavy metal pollution and removal in shellfish

With the continuous development of industry and economy, heavy metal pollution in water has been an important environmental problem in China. Shellfishes have strong ability of heavy metal enrichment due to their characteristics of filter-feeding, which has seriously affected the safety of shellfish products, and caused trade barriers for shellfish export. Therefore, effective control of shellfish heavy metal pollution has become an urgent problem. This paper reviewed the current status of heavy metal pollution in shellfish, introduced two aspects of heavy metal removal technologies including live shellfish removal and shellfish hydrolyzate removal methods, and the problems remained for further studies were also indicated. This review would provide references for the research of heavy metal removal technology in shellfish.
