摘　　要：砷为广泛存在于自然界中的一种元素,在环境中表现出复杂的地球化学性质,不同形态的砷在大气、土壤及水体中的迁移和富集受许多物理化学因素的制约,并产生毒害程度不同的环境效应。总结砷的来源、其在不同环境介质中的存在状态及砷污染对生态环境的影响,提出应在了解不同介质环境中砷的赋存状态后,采用不同的治理方法有效地去除砷,以最大程度地降低砷对人体健康及生态环境造成的危害。Arsenic widely exists in nature and displays complicated geochemistry properties.In atmosphere,soil and water systems,and transfer and accumulation,different form of Arsenic are influenced by many physicochemical factors,and different forms of arsenic could have effects of different toxic levels on the environment.Source of arsenic,existing state of arsenic in different environmental mediums and influence on ecology environment by arsenic contamination were summarized in this paper,and it was proposed that existing state of Arsenic should be known before removing arsenic effectively by various treatment methods,so as to decrease,to the greatest extent,the hazards to human health and ecology environment.
