Following the guidelines for soil environment assessment and risk assessment issued by the Ministry of Ecology and Environment, an assessment was conducted on the site where illegal lead ingot production had taken place through illegal smelting processes. By collecting data and conducting current status monitoring, the results indicated that the levels of lead and arsenic in the soil exceeded the regulatory values for Class II land use. However, the groundwater monitoring parameters met the Class III standards specified in GB14848-2020, indicating that the groundwater in the area is not contaminated.展开更多
