海洋沉积物中重金属污染防治研究进展

重金属污染是海洋沉积物污染的一个重要方面。文章概述了近几年来国内外对研究海洋沉积物中重金属样品的预处理、污染元素的测定以及其研究方法中的一些特点,以期进一步推动海洋沉积物中重金属污染防治的深入发展。同时结合现代生物修复和化学治理技术,提出一些预防和治理海洋沉积物中重金属污染方面的设想。化学治理技术中,较详细介绍了壳聚糖在治理海洋沉积物中重金属污染的潜在应用价值。

REVIEW OF PREVENTION OF HEAVY METAL POLLUTION IN MARINE SEDIMENTS

Heavy metals in marine sediments can cause many serious pollution problems. The sample pretreatment and elemental composition measurement of heavy metals in marine sediments, as well as some characteristics in the recent research methods, were summarized in this paper. It is hoped to make further progress in prevention of heavy metal pollution in marine sediments. According to modern bio-mediation and chemical control technologies, some tentative plans to prevent or reduce the concentrations of heavy metals in marine sediments were put forward at the same time. And in the chemical control, the potential application of Chitosan in prevention of heavy metal pollution in marine sediments was introduced in detail.
