摘　　要：对某包含废弃砖瓦厂在内的地块进行土壤污染状况调查研究,采用收集资料、现场踏勘、人员访谈等方式,结合生产历史,对地块内的疑似污染区域进行识别,并对可能造成污染的特征因子进行重点关注。根据国家和上海市相关技术要求,在地块内分重点的布置土壤监测点位并取样,然后对样品数据进行检测分析,得出污染因子的浓度及分布特征情况。砖瓦厂过往的生产活动导致了土壤中重金属(铅、镍)、石油烃(C_(1)0~C_(4)0)以及半挥发性有机物(多环芳烃)的污染,其中多环芳烃的污染情况最为严重。从整体来看,大部分污染物的污染程度随着土壤深度的增加而逐渐降低,污染主要集中在填土层和粉质黏土层中。研究可为砖瓦厂污染地块调查评估提供参考。The soil pollution status of a plot containing an abandoned brick and tile factory was investigated,suspected contaminated areas in the plot by means of data collection,site survey,personnel interview and other methods combined with production history were identified,focuing on the characteristic factors which may cause pollution.According to the relevant technical requirements of the state and Shanghai,arranging soil monitoring points in the plot and taking samples,the sample data were tested and analyzed to obtain the concentration and distribution characteristics of pollution factors.The past production activities of brick and tile plants were resulted in soil pollution of heavy metals(lead,nickel),petroleum hydrocarbons(C_(1)0~C_(4)0)and semi-volatile organic compounds(polycyclic aromatic hydrocarbons),of which the most serious pollution was polycyclic aromatic hydrocarbons.The pollution degree of most pollutants decreased gradually with the increase of soil depth,and the pollution was mainly concentrated in the fill soil layer and the silty clay layer.The research can provide reference for the investigation and evaluation of the contaminated land of brick and tile factory.
