Abstract
1. Fifty-three samples of freshwater fishes and prawns comprising twenty species from the States of Maharashtra, Gujarat and Bihar were analysed for their contents of calcium, potassium, phosphorus, copper and iron. The seven samples from Bihar were analysed, in addition, for uranium.
2. Significant differences were observed between fishes and prawns in regard to copper and calcium contents in edible portions. Thus, the copper content of prawns ranged from 4·62 to 13·11 ppm; while in the fishes the corresponding range was 0·13 to 3·19 ppm. The uranium content of the fish samples from Bihar was of the order of 0·2 ppm.
3. Data are also given on the analyses of the water samples and on Concentration Factors. The Concentration Factors are discussed with reference to the estimation of maximum permissible concentrations of the radioisotopes of the elements in water.
