摘　　要：异味污染问题在化工、农药等污染地块普遍出现,制约着行业规范化发展,土壤中污染物成分复杂性和地块性质差异性使得识别并进行土壤异味定量化评估存在一定困难。本文以上海市某污染地块为研究区域,将双元平衡理论与挥发因子模型、异味活度值计算进行结合,得到适合本研究案例的异味评估模型,并利用该模型计算得到污染地块土壤中异味有机污染物是以苯系物为主。本文提出的异味评估方法可为土壤异味控制和修复目标制定提供一定思路。The problem of odor pollution is common in chemical,pesticide,and other polluted plots,which restricts the standardized development of the industry.The complexity of pollutant components in soil and the differences in plot properties make it difficult to identify and quantitatively evaluate soil odors.This article takes a polluted land parcel in Shanghai as the research area,combines the dual equilibrium theory with the volatility factor model and odor activity value calculation to obtain a suitable odor evaluation model for this study case.Using this evaluation model,it is calculated that the odor organic pollutants in the soil of the polluted land parcel are mainly benzene series compounds.The odor assessment method proposed in this article can provide some ideas for soil odor control and remediation goals.
