摘要：
The pollution degree, distribution characteristics, and synergistic ecological risk of heavy metals were studied by analyzing the contents of As, Cd, Cr, Pb, Hg, and Ni values in soil and groundwater of three types of typical industrial land (chemical industry, metal processing, and hazardous waste treatment) in Shanghai. The results showed that the soil and groundwater in 30 potential pollution areas of the three types of industrial land were polluted by heavy metals. Cd, Cr, Pb, Hg, and Ni were obviously accumulated in the surface soil, whereas As, Cr, Pb, and Ni were accumulated in the groundwater. The content and variation coefficients of heavy metals in the soil gradually decreased with the deepening of vertical depth, indicating that the impact of human activities was lessened. The pollution sources of the various heavy metals were different; Cr and Hg in the soil were mainly from metal processing and the hazardous waste treatment industry, whereas Cd, Pb, and Ni were accumulated in the soil of all three industries. In groundwater, As mainly came from the chemical industry and hazardous waste treatment industry, Cr mainly came from the metal processing industry, Ni mainly came from metal processing and the hazardous waste treatment industry, and Pb accumulated in groundwater of all three industries. The Nemero comprehensive pollution index of the soil and groundwater in the metal processing industry was the highest. Cr, Pb, and Ni in the metal processing industry had synergistic pollution characteristics in soil and groundwater, which may have been closely related to soil heavy metal content, migration, and enterprise management level. The potential ecological risk of heavy metals in soil and groundwater was generally in the mild to moderate range, the potential ecological risk level of Hg and Cd in soil was relatively high, which was mainly affected by the toxicity of heavy metals, and the potential ecological risk level of Ni in groundwater was relatively high, which was mainly affected by the content of heavy metals. © 2022 Science Press.
