随着矿产资源的开发和工业废水的违规排放，大量的重金属元素随水循环系统污

With the development of mineral resources and the illegal discharge of industrial wastewater, a large amount of heavy metal elements pollute the groundwater along with the water circulation system. Other heavy metal pollutants such as lead and chromium are not easily degraded in organisms and their accumulation is potentially harmful to human health.
