于桥水库表层水中溶解性有机质的变化特征及其与铜的络合机制的研究
发布时间：2021-12-18 15:51
溶解有机质（Dissolved Organic Matter,DOM）在自然水体中普遍存在,对自然环境系统运行和水环境演变起到重要作用。溶解性有机质包括腐殖质、蛋白质等大分子物质以及小分子的氨基酸,碳水化合物,糖类等物质的复杂有机混合物。它是异养型微生物重要的能量和营养来源,是各种养分（C、N、P和S）循环的关键环节,也是环境污染物的重要络合剂或吸附剂。溶解有机质中富含-COOH、-OH、-NH2以及-C=O等官能团,可以与重金属离子发生配位、络合反应,影响重金属的溶解性和生物有效性,从而影响重金属的生物可利用性、毒性、迀移转化和归趋。然而,不同来源、不同结构组成、不同分子量的DOM对重金属的环境行为的影响有着显著差异,而这方面的研究还需要深入。近年来,人类活动极大地改变了水体DOM的来源、动态、结构和组成特性。其中,筑坝是最显著和最广泛的人为扰动事件。随着经济和社会发展的需要,兴建各型水库已成为缓解全球日益短缺的淡水资源供需矛盾的重要途径。虽然河流筑坝对社会经济发展具有重要支撑作用,但是河流筑坝拦截改变天然河流原有的自然属性和内部的作用过程,为营养元素的输送产生...
