Exposure of Fluoride in Coal Basin

Abstract

Coal is a dirty fuel contaminated with F − and other elements. Several million tons of coal are burnt in Korba basin, central India to generate electricity with pouring fluorine and other elements into the environment. The water is contaminated with F − and other chemicals beyond the permissible limits. The contaminated water is consumed by the human and animals by excreting the balanced toxicants through the stool and urine. Several folds higher concentration of F − in urine (44 mg/L) and stool (266 mg/kg) samples of the cattle are observed. The prevalence of fluorosis diseases in cattle of the Korba basin is reported.

Coal mine waste characterization and defluoridation property

“…In India Rajasthan, Gujarat and Andhra are worst affected due to fluorosis [ 4 ]. In India high concentration of fluoride has been observed in many coal mining areas [ [18] , [19] , [20] ].…”

Efficient Removal of Fluoride by Complexation Extraction: Mechanism and Thermodynamics

“…The adverse effects of excessive fluoride on health 1 and equipment 2 have received significant attention in recent years. Industries involving semiconductor production, 3 electroplating, 4 glass and ceramic production, rubber and fertilizer manufacturing, and coal power plants 5 discharge high-fluoride wastewater. The fluoride concentration in industrial effluent is generally very high, ranging from tens to thousands of milligrams per liter.…”
