FLUORIDE CONTAMINATION OF GROUNDWATER
TOPIC: Environment
Context- Continued fluoride contamination of groundwater is a glaring public health issue in central India.
Concept-
Fluoride Contamination:
- Fluoride is a chemical element that is found most frequently in groundwater and has become one of the most important toxicological environmental hazards globally.
- The occurrence of fluoride in groundwater is due to weathering and leaching of fluoride-bearing minerals from rocks and sediments.
- Fluoride when ingested in small quantities (<0.5 mg/L) is beneficial in promoting dental health by reducing dental caries, whereas higher concentrations (>1.5 mg/L) may cause fluorosis.
- Although the surface water is less contaminated, tubewells pump out water that contains high fluoride content.
- Rajasthan, Andhra Pradesh, Telangana, Tamil Nadu, Gujarat, and West Bengal are the relatively high-fluoride-contaminated states in India.
- Dark yellow pigmentation of their teeth – a common visible sign of excessive ingestion of fluoride.
- Fluoride contamination leads to damaged joints, bone deformities, flurosis.
