土壤重金属污染的危害以及防治措施

open access: yes地矿测绘, 2020
因为受到经济发展的推动作用,人们的生活质量也在快速提高,但是生活垃圾和生产垃圾的增加严重的影响了生态环境。其中就包括土壤污染问题,人们的生活生产产生的一些垃圾,使得土壤中的重金属物质越来越多,而这些重金属物质都严重的影响着人们的生命健康。土壤已经被污染,人们在这样的土地上种植庄稼,人们吃了受污染的庄稼,有害物质就会被人体吸收,时而久之,就会患得比较严重的病。所以保护土壤环境,防止土壤被污染是人们首要任务。

探究城市土壤重金属污染分析及防治对策

open access: yes工程技术与管理, 2020
在目前的城市土壤污染中,重金属污染构成了典型的土壤污染来源。城市土壤如果含有超标的重金属,则会造成程度比较显著的城市土壤污染。在情况严重时,遭受重金属污染的城市土壤环境还会威胁到城市居民的日常饮食安全,增大了土壤生态污染的风险。因此对于城市土壤遭受重金属污染的状况而言,基本思路在于明确土壤重金属污染的成因,结合城市土壤的污染情况探求防治土壤污染的举措。
