Abstract

In order to explore the distribution of typical soil pollutants in the retired site of the original Jema chemical plant, this paper selects the observation point to determine the typical pollutants and the spatial distribution of pollutants by the method of high-density electrical resistivity tomography (ERT) and thus analyze the typical pollutants combined with Hydrus-1d software. The results show that the typical soil pollutants are volatile organic matter, and pesticides respectively, and are mainly distributed in the water-rich area of weathered cracks. After about 600 days, the soil pollutants show an overall decline trend, and completely reach the groundwater after about 2400 days.
