摘要：
Increasing attention has been paid to the heavy metal pollution in groundwater. The source analysis and risk assessment of heavy metals will provide data and method support for the targeted control of heavy metal pollution in groundwater. In this study, 20 sampling sites were selected in Shijiazhuang City. The APCS-MLR model and health risk model were applied to analyze and evaluate the pollution sources and health risks of 10 types of heavy metals in the groundwater of Shijiazhuang. The results showed that 1 the mean concentration of heavy metals in groundwater followed the order of Fe > Zn > Mn > Cu > Al > Pb > Cr > As > Cd > Hg, and the mean ρ(Fe) and ρ(Pb) were 260. 3 μg·L - 1 and 10. 01 μg·L - 1 , respectively. According to the results of the single factor and Nemerow index, Pb, Fe, and Cd primarily contributed to the heavy metal pollution in the groundwater. 2 The concentration of heavy metals ranged from 47. 30 to 2 560 μg·L - 1 . In terms of spatial distribution, the highest concentration appeared at S3 (2 560 μg·L - 1 ), whereas the lowest concentration was at S9 (47. 30 μg·L - 1 ). 3 Source analysis results showed that industrial and agricultural activities, transportation emission, and geological background were the major heavy metal sources, among which the contribution of industrial and agricultural activities was the highest (47. 83%). 4 The industrial-agricultural activities posed a potential threat to adults (HI >1); however, the non-cancer and the cancer risks of other sources for both adults and children were at an acceptable level (HI < 1) and potential threat level, respectively; industrial-agricultural activities were the major source of non-cancer (adults: 52. 46%, children: 52. 45%) and cancer risks (adults: 65. 22%, children: 65. 69%), among which Cd and As showed high cancer risk. Therefore, to ensure the safety of the groundwater environment, strictly controlling the pollution sources and further strengthening the risk control of heavy metal pollution in groundwater are necessary. © 2023 Science Press.
