[Spatial and Temporal Variations of Heavy Metals and Probabilistic Health Risks in Groundwater Drinking Water Sources in the Yellow River Basin].
Abstract
were associated with the migration and transformation of Mn， Fe， and As. The health risk assessment results showed that heavy metals had no significant potential non-carcinogenic risk or carcinogenic risk to human body， but under extreme conditions， both the non-carcinogenic risk value （HQ） and carcinogenic risk value （CR） of As exceeded the standard values in different age groups， and As contributed more than 84% to total CR in three age groups. Therefore， it is recommended to improve the quality of groundwater drinking water sources by strengthening the source control measures and preventive measures and to strengthen the risk prevention and control of As to reduce its risk to human health.
