“…Carcinogenic heavy metals are the main reasons affecting human health. For As and Cr, soil treatment and remediation should be enhanced so that the soil heavy metal content is in line with the local background value [ 27 ]. Relevant government agencies have established long-term and regular monitoring mechanisms, such as measuring and analyzing the content of heavy metals in the soil regularly in the dry and wet seasons so that the soil sources of heavy metals in groundwater can be effectively controlled.…”

Heavy metals pollution in groundwater and the resulting health risks have always been an environmental research hotspot. However, the available information regarding this topic and associated methods is still limited. This study collected 98 groundwater samples from a typical agricultural area of Songnen Plain in different seasons. The pollution status and sources of ten heavy metals (As, Ba, Cd, Co, Cr (VI), Cu, Fe, Mn, Ni, Pb, and Zn) were then analyzed and compared. In addition, the human health risks assessment (HHRA) model was used to calculate human health risks caused by heavy metals in groundwater. The results revealed that heavy metals were mainly distributed in the northwest of the study area and along the upper reaches of the Lalin river and that the concentrations of heavy metals were higher during the wet season than the dry season. Industrial and agricultural activities and natural leaching are the main sources, and each kind of heavy metal may have different sources. Fe and Mn are the primary pollutants, mainly caused by the native environment and agricultural activities. The exceeding standard rates are 71.74% and 61.54%, respectively based on the Class III of Quality Standard for Groundwater of China (GB/T 14848-2017). The maximum exceeding multiple are 91.45 and 32.05, respectively. The health risks of heavy metals borne by different groups of people were as follows: child > elder > young > adult. Carcinogenic heavy metals contribute to the main risks, and the largest risks sources are Cr and As. Therefore, the government should appropriately restrict the use of pesticides and fertilizers, strictly manage the discharge of enterprises, and control man-made heavy metals from the source. In addition, centralized water supply and treatment facilities shall be established to prevent the harm of native heavy metals.

“…Heavy metals in groundwater come from various sources, and a kind of heavy metal may have various sources. The correlation analysis between heavy metals in groundwater can reveal the sources of heavy metals effectively [ 27 ]. In this study, Spearman correlation was performed to calculate the significance and correlation coefficient.…”
