Fluoride levels in drinking water and other surface water of an industrial area belt of Orissa State in India.

The fluorosis problem along with endemicity characterised by high degree of industries releasing fluorides into the environment was studied to quantify the fluoride levels in the different water sources. The analysis showed that out of 17 tube wells monitored, three (17.65%) showed higher fluoride levels. Among the open well monitored, 17 (58.54%) had higher fluoride content out of 41. The samples collected at open ponds showed that nine (47.37%) samples had higher fluoride content. The comparisons were made with the control samples. [ABSTRACT FROM AUTHOR]
