【摘要】 金属离子与有机污染物可通过多种方式同时存在于环境中,形成复合污染。由于金属离子与有机污染物的相互作用,二者的物理化学性质、迁移转化规律以及生态毒性效应都发生了变化,给污染物的水处理过程以及污染物的生态毒性评估带来极大的挑战。综述了环境中金属-有机物复合污染的来源、金属离子与有机污染物之间的相互作用、共存对二者去除效率的影响以及复合污染的生态毒性研究,以期为复合污染的防治与处理工艺研究提供参考。更多还原

【Abstract】 Metal ions and organic pollutants can coexist in the environment in a variety of ways and therefore,generate combined pollution.Because of the interaction between metal ions and organic pollutants,their physicochemical property,transformation,and eco-toxicity would change,which gives rise to great challenge for the water treatment process and ecological toxicity assessment of these pollutants.This paper reviews the sources of combined pollution,the interaction between metal ions and organic pollutants,the influences of coexistence on the removal efficiency of both metal ions and organic pollutants,and the studies on ecological toxicity of combined pollution,which aims to provide a theoretical reference for the prevention and treatment of combined pollution.更多还原
