Abstract

Abstract

To clarify the distribution and migration characteristics of volatile organic compounds (VOCs) in organic pollution sites, 120 soil and 48 soil gas sampling holes were arranged at a site where a chemical plant was once located, and 97 pairs of soil/soil gas samples were collected from 14 holes in the heavily polluted area. The pollutant concentrations in the samples were determined through laboratory analysis. The distribution characteristics of the pollutants were analyzed using Sufer software, and the distribution and migration characteristics of trichloroethylene (TCE) were interpreted in combination with the stratigraphic lithology. The applicability of two models for predicting the content of soil gas VOCs was analyzed with predicted and measured values. The results show that as the hole depth increases, the TCE concentration in the soil in the heavily polluted area decreases with an exceedance rate of 50.4%. The maximum value is in the clayey silt layer (1610 mg/kg), exceeding the standard by 2300 times. The TCE concentration in soil gas first increases and then decreases, with the maximum value occurring in the sandy soil layer (643 mg/m³), exceeding the standard by 546 times with an exceedance rate of 97.9%. The TCE concentration in soil and soil gas outside the heavily polluted area first increases and then decreases with soil depth, and the exceedance rate is 6.6% and 54.9%, respectively. The horizontal migration of TCE is weaker than its vertical migration. The area that exceeds the standard first increases and then decreases with soil depth, and the average exceedance area is 7.3 × 10³ m². TCE in soil gas spreads rapidly from the heavily polluted area to the surrounding areas. The exceedance area covers the entire chemical plant area and pollutes the area outside the chemical plant. The average exceedance area is 2.4 × 10⁴ m². Based on the soil TCE concentration, both the linear model and the dual equilibrium desorption (DED) model can predict the soil gas TCE concentration. The proportion of data points with a prediction error of one order of magnitude or less for the two models is 78.6% and 71.4% for the fill and sandy soil, respectively. Regression analysis shows that the DED model predicts soil gas TCE concentrations more close to the actual values for fill (irreversible adsorption degree f = 0.1), silty clay (f = 1.0), and clayey silt (f = 0), while the linear model and DED model yield relatively close predictions of soil gas TCE concentrations for sandy soil. When a pollution assessment and secondary development of similar sites are conducted, the concentrations of soil gas pollutants should be monitored or predicted to avoid underestimating the degree and scope of site pollution.
