Fluoride and nitrate contamination of groundwater in the Loess Plateau, China: Sources and related human health risks
Highlights Fluoride and nitrate sources were identified by chemical and isotopic analysis. Water-rock interaction, evaporation and anthropogenic activities control F– contents. Major nitrate sources are soil N, chemical fertilizers, and manure and sewage. Absence of denitrification emphasizes the importance of controlling nitrate sources. Non-carcinogenic health risks of fluoride and nitrate increase with decreasing age. Abstract […]

Fluoride abundance and their release mechanisms in groundwater along with associated human health risks in a geologically heterogeneous semi-arid region of east India
Highlights Assessed groundwater fluoride level and its genesis in a semi-arid region Source of fluoride is mainly geogenic, influenced largely by pH and HCO3– ions Health risk assessed using dose-response characterization and the USEPA method Health risk evaluated via multiple exposure routes on different populations groups Infant and child age groups have more health risk […]

Fluoride in Drinking Water: A Scientific Review of EPA’s Standards.
Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary maximum contaminant level […]

Hydrogeochemical Evaluation, Suitability, and Health Risk Assessment of Groundwater in the Watershed of Godavari Basin, Maharashtra, Central India.
Abstract In this investigation, the geochemical progression of a total of 31 groundwater samples of pre-monsoon season was assessed with categorization based on entropy weight water quality index and risk assessment on public health in the semi-arid area of Godavari basin, Maharashtra, Central India. Graphically, the major groundwater types identified were Ca–HCO3, mixed Ca–Mg–Cl, and […]

Action Alert: EPA Searching for Incinerators to Quickly Conduct an Experiment On PFAS in Emissions.
Contact Your State Environmental Commissioner to Stop This From Happening in Your State The Issue: While the disposal of PFAS chemicals poses serious challenges, the rush to burn these chemicals is on, despite no evidence they can be safely incinerated. EPA is trying to find an incinerator to be part of an experiment regarding PFAS […]

Hydrogeochemistry and fluoride contamination in Jiaokou Irrigation District, Central China: Assessment based on multivariate statistical approach and human health risk.
Highlights The relationships of fluoride and other ions were analyzed using correlation matrices, principal component analysis. Hydrogeochemical controls on high fluoride groundwater chemistry were determined. Non-carcinogenic health risks of fluoride were assessed via different pathways. This study draws attention to the management of high fluoride groundwater to achieve sustainable development Too little and too much […]

Health Effects of Ingested Fluoride
Excerpts: INTRODUCTION Fluoridation of drinking water has been a subject of controversy for decades. Over the past 50 years, the incidence of dental caries (cavities) has declined considerably in the United States, an important health advance that most scientists attribute principally to increased access to fluoridated water and dental products. According to the U.S. Centers […]
