汾河流域地下水化学演化特征、控制因素及健康风险评价
Hydrochemical Evolution Characteristics,Control Factors and Health Risk Assessment of Groundwater in the Fenhe River Basin
摘要
Abstract
The issue of groundwater pollution in the Fenhe River is becoming more and more serious and the water quality is deteriorating,resulting in the daily drinking water safety of residents in the Fenhe River Basin.In this paper,we selected groundwater in the Fenhe River Basin in the eastern part of the Loess Plateau as the research object,and comprehensively used mathematical statistics,graphical methods,correlation analysis,forward model,geographic detector and health risk assessment model to analyze the spatial-temporal evolution character-istics of groundwater chemistry,explore the formation mechanism of groundwater chemistry and quantify the contribution of different sources,identify the controlling factors of groundwater chemical evolution,and quantitatively evaluate the risks to human health through drinking wa-ter.The results show that the hydrochemical type of Fenhe River Basin evolves from HCO3-Ca to HCO3-Ca·Mg and SO4 HCO3-Ca·Mg;carbonate weathering and silicate weathering are the main sources of groundwater chemical composition.The main control factors of groundwa-ter chemical evolution are elevation and ecosystem,and ecosystem and land use.The non-carcinogenic risk factor of nitrate to children through drinking water is greater than that of adults.关键词
