Hyderabad groundwater shows high nitrate, fluoride levels posing risks to children
- A study found elevated nitrate and fluoride in Hyderabad's groundwater, posing higher health risks to children.
- Nitrate exceeded safe limits in up to 40% of samples, while fluoride exceeded limits in up to 64% of samples.
- The mean hazard index for children rose to 3.78, above the safe threshold of 1, indicating non-carcinogenic risk.
- Researchers linked nitrate to fertiliser and sewage, and fluoride to granitic rock weathering, urging closer monitoring.
