Evaluation of straw ash as a cost-effective adsorbent for the removal of phosphate and fluoride from aqueous solution
Abstract In the present study, the straw ash (SA) was proposed to remove phosphate and fluoride from aqueous solution. The effects of SA dosage, initial contaminants concentration and initial pH on removal efficiency, adsorption kinetics and isotherms were investigated in batch experiments. The removal mechanisms were also discussed. The results show that solution pH was […]

DNA methylation and fluoride exposure in school-age children: Epigenome-wide screening and population-based validation.
4. Discussion Water-borne endemic fluorosis has been widely prevalent in China, especially in the central, western and northern parts of China. In order to explore the possible epigenetic changes caused by fluoride exposure, we conducted a screening and validation study in step by step. We undertook, for the first time, microarray analyses of DNA methylation […]

Hydrochemistry and fluoride contamination in Ndali-Kasenda crater lakes, Albertine Graben: Assessment based on multivariate statistical approach and human health risk.
Abstract Hydrochemistry of crater lakes (n=15) in the Ndali-Kasenda cluster was deciphered using standard methods of the American Public Health Association to understand the major ion chemistry; spatial distribution, occurrence, and non-carcinogenic health risks due to exposure to fluoride levels in the lakes in Ndali- Kasenda cluster, Albertine Graben. Numerous economic activities take place in […]

Human health risk assessment of metals and anions in surface water from a mineral coal region in Brazil
Abstract Coal mining releases high concentration elements to the environment, which can be deposited in surface water, causing several human health problems. Candiota mine in the south of Brazil is the largest coal reserves in the country, representing approximately 40% of total national coal reserves. Therefore, the present study aimed to estimate the chronic daily […]

Not just groundwater, fluoride has poisoned agricultural soil, crops in Bengal
Farmers in Bankura and Purulia rely on groundwater, heavily contaminated with flouride, to cultivate crops West Bengal has been grappling with groundwater contamination for decades. About 12 per cent of the population in eight of the state’s 23 districts is impacted by water contaminated by fluoride. The contamination is higher in western parts of the […]

A holistic study on fluoride-contaminated groundwater models and its widespread effects in healthcare and irrigation
Abstract Groundwater is a key resource in the world. Its importance is often undermined, despite the various applications which include irrigation, drinking, sanitation, and industrial uses. One of the contaminants of groundwater is fluoride or the fluorine ion. Fluoride is a common pollutant of water, carrying potential benefits and costs to various sectors. Fluoride contamination […]

Fluoride concentration in bottled drinking water from a fluoride endemic area: a market-based survey
Summary Drinking water is the primary source of fluoride intake for humans around the world. In southern Algeria, dental fluorosis is considered an epidemic that is spreading among the population by health professionals. Thus, the consumption of bottled water is important because it is considered safer for health. Objectives This study aims to determine the […]

Fluoride concentrations in drinking water and health risk assessment in the south of Algeria
Highlights This was the first study in Algeria that measure fluoride hazard quotient thought water ingestion. Forty-two water samples were collected during the spring season in 2021. A mean fluoride level of 1.07 ± 0.38 mg/L was found. Rural population were more exposed for fluoride than main city population. HQ values were high to 1 for infants and […]
