Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

Dental fluorosis in the European roe deer (Capreolus capreolus): A review of the pathological changes in the enamel of fluorotic cheek teeth and the abnormal pattern of dental wear in affected dentitions

The Anatomical Record, Volume 309, Issue 1, Page 166-186, January 2026.
Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...

A Review of fluoride and its diverse effects

SRM Journal of Research in Dental Sciences, 2014
Increased intake of fluoride in water and diet results in dental and skeletal fluorosis. Many states in India are affected by fluorosis. The optimum level of fluoride in drinking water for anti-cariogenic effect was thought to be 1 ppm.
