摘　　要：选取多年废弃镁渣堆场进行环境监测调查,通过采样,布点分析了该场地下的土壤和周围的地下水污染情况。结果表明,该镁渣堆场土壤符合GB 15618—2018的规定,只是pH值和Mg含量相对偏高。但周围地下水的总硬度、氨氮质量浓度在镁渣堆场距西200 m处超出了GB/T 14848—2017Ⅲ类标准的要求,且总硬度、氨氮、亚硝酸盐氮和镁含量随着与镁渣堆的距离远近,整体呈现向外扩散趋势。The abandoned magnesium slag dump site for many years was selected for environmental monitoring and investigation,and the soil under the site and the surrounding groundwater pollution were analyzed by sampling.The results indicate that the soil of the magnesium slag pile meets the requirements of GB15618-2018,but the pH value and Mg content are relatively high.The content is relatively high.However,the total hardness and ammonia nitrogen of the surrounding groundwater exceed the requirements of GB/T14848-2017 Class III standards at a distance of 200 meters to the west of the magnesium slag yard.And the total hardness,ammonia nitrogen,nitrite nitrogen,and magnesium content show an overall outward diffusion trend from the distance of magnesium slag pile.
