On the distribution of fluoride, calcium and magnesium in the waters off the central west coast of India

Abstract

The distribution of fluoride, calcium and magnesium was studied in the waters off the central west coast of India. The averages F/Cl, Ca/Cl and Mg/Cl ratios observed are (6.83 plus or minus 0.023) x 10@u-5@@, (0.02194 plus or minus 0.00068) and (0.06332 plus or minus 0.0027) respectively. The depthwise variations of fluoride, calcium and magnesium and their ratios to chlorinity have been discussed
