A Review of Geochemical Behaviors and Environmental Effects of Organic Matter in Sediments

水体沉积物是重金属、有毒有机化合物等环境污染物及C、N、P等营养元素的汇和释放源,而有机质对这些污染物和营养元素在沉积物中的迁移、转化等地球化学行为中起着至关重要的作用.本文就近期有关沉积物中有机质的环境地球化学行为方面的研究进行了综述,重点评述了有关沉积物中有机质本身的来源、性质、迁移和矿化及其环境效应等方面的研究进展.;Sediments is an important sink and sources of pollutants and nut ritive elements, such as heavy metals, organic toxicants, phosphorus, nitrogen, and carbon.In the sediments, organic matter is the key factor to control the environmental behaviors of these substances.In this paper, the...
