摘　　要：以某化肥企业退役场地为例,基于GIS和EVS方法,开展场地的氨氮和挥发性有机污染物污染状况调查与特征分析。结果显示,场地主要超标特征污染物是氨氮和1,2-二氯乙烷;土壤中氨氮超标点位浓度最大值为2808 mg·kg^(-1),包气带最下段土层中基本已无氨氮污染,而潜水含水层土层中氨氮污染却又加重,说明地下水中氨氮污染可能存在污染物传输的优先通道;土壤中1,2-二氯乙烷未超标,地下水中1,2-二氯乙烷超标点位浓度最大值为1188.52μg·L^(-1),说明土壤中污染物未超出筛选值无法作为地下水中污染物未超标准限值的表征条件,土壤和地下水样品的采集检测均有必要;PID快速检测结果与厂区的污染源分布情况相符,对于初步筛选采集具有代表性的土壤样品具有较强的辅助作用。This paper takes the decommissioning site of a fertilizer enterprise as an example to investigate and and analyze the pollution status of ammonia nitrogen and volatile organic pollutants based on GIS and EVS methods.The results showed that the main characteristic pollutants exceeding the standard were ammonia nitrogen and 1,2-di-chloroethane.The maximum concentration of ammonia nitrogen in soil was 2808 mg·kg^(-1).There was no pollution of ammonia nitrogen in the bottom layer of the vatted zone,but the pollution of ammonia nitrogen in the phreatic aquifer was aggravated,indicating that there may be a priority channel for the pollution of ammonia nitrogen in the groundwa-ter.1,2-dichloroethane in soil did not exceed the standard,but the maximum concentration of 1,2-dichloroethane in the groundwater was 1188.52μg·L^(-1),indicating that the pollutants in soil not exceeding the screening value could not be used as the characterization condition of the pollutants in the groundwater not exceeding the standard limit.It is necessary to collect and test soil and groundwater samples.The results of PID detection were consistent with the distribution of pollution sources in the plant area.PID rapid detection has a strong auxiliary role in preliminary screening and collection of representative soil samples.
