[Groundwater Chemical Characteristics, Control Factors, and Health Risks in the Dahei River Basin of Typical Tributary of the Yellow River].
摘要
mainly derived from the dissolution of carbonate rocks. ④ The PMF source analysis identified four influencing factors, namely, water-rock interaction-agricultural activities, domestic wastewater-industrial activities, agricultural-industrial activities, and the factor of evaporation and concentration, The contribution ratio of the influencing factors in different hydrological periods varied, with water-rock action-agricultural activities dominating in the abundant water period, while human activities and evaporation concentration were more prominent in the dry water period. By revealing the control factors of groundwater hydrochemistry and their health risks in typical tributaries of the Yellow River Basin, scientific references can be provided for the control and management of regional groundwater quality standards.
