矿区泥石流灾害对土壤重金属污染的影响与控制方法研究

Influence of Debris Flow Disaster in Mining Area on Soil Heavy Metal Pollution and Control Method

选取某省地质环境监测下的重金属矿山区作为测试区域,在矿区资料库采集相关信息。将采样点设置为12处,主要集中在村民聚集地域、矿山周边。检测研究区域采集的样本重金属元素,将所得结果和衡量标准进行比较,同时采用SPSS软件实行统计分析。经分析得到枯水期和丰水期土壤重金属含量相关数值,枯水期土壤重金属污染指数最大的是Sb,最小的是Co;丰水期土壤重金属污染指数最大的是Sb,最小的是Ni;矿区泥石流灾害下土壤重金属污染严重,诱导农作物生成次生污染,农作物重金属含量超标。

The heavy metal mining area under the geological environment monitoring of a certain province is selected as the test area,and relevant information is collected in the mining area database.Setting the sampling point to 12,this paper mainly concentrated in the area where the villagers gather and around the mine.The samples were collected for heavy metal elements in the study area,and the results were compared with the metrics.Statistical analysis was performed using SPSS software.The correlation between the heavy metal content in the dry season and the wet season was obtained.The highest heavy metal pollution index in the dry season was Sb,and the smallest was Co.The most serious heavy metal pollution in the wet season was Sb,and the smallest was Ni.Under the mudslide disaster in the mining area,the heavy metal pollution in the soil is serious,and the secondary pollution of crops is induced,and the heavy metal content of crops exceeds the standard.
