南昌某农用地土壤污染状况调查研究

Investigation on Soil Contamination of an Agricultural Land in Nanchang

摘要: 以南昌市某农用地为研究对象，对地块进行了污染识别和初步采样分析。调查结果表明：地块内现状及历史上主要为农用地，部分区域存在回填土壤和非规模化养猪场，地块周边现状及历史上主要存在污水处理站、加油站，可能会对地块土壤环境产生影响；地块及周边区域土壤各项监测指标均低于《建设用地土壤污染风险管控标准(试行)》(DB36/1282-2020)中第二类用地筛选值，土壤总体无污染；地下水各指标中浊度、色度、高锰酸盐指数、肉眼可见物、锰超《地下水质量标准》(GB/T 14848-2017) III类限值，地下水总体水质较好。综上所述，本调查地块的环境状况良好，可以满足商服用地开发利用要求。

Abstract: An agricultural land in Nanchang City was taken as the research subject, and pollution identification and preliminary sampling analysis were conducted on the site. The survey results show that the current situation in the plot and its historical use mainly consist of agricultural land, with some areas containing backfill soil and non-scaled pig farms. The surrounding area of the plot has mainly had sewage treatment plants and gas stations in its history, which may have an impact on the soil environment of the plot. All monitoring indicators of the soil in the plot and surrounding areas are lower than the screening values for Class II land in the “Technical Guidelines for Risk Assessment and Control of Soil Pollution on Construction Sites” (DB36/1282-2020), indicating that the soil is overall non-polluted. The turbidity, chromaticity, permanganate index, visible objects, and manganese content in the groundwater all meet the Class III limits set out in the “Groundwater Quality Standards” (GB/T 14848-2017). Overall, the groundwater quality is relatively good. In summary, the environmental conditions of the surveyed land plot are good and can meet the re-quirements for commercial and service land development and utilization.
