Alterations in the acid and alkaline phosphatase quantities in fluoride exposed estuarine goby boleophthalmus dussumieri



Alterations in the acid and alkaline phosphatase quantities in fluoride exposed estuarine goby boleophthalmus dussumieri



Fluoride 21(3): 131-136



An edible goby B. dussumieri, which abounds in the estuaries of South Gujarat coast (21.degree. 12'N and 72.degree. 50'E) has been chosen for current experiments. The fish were subjected to sublethal concentrations of sodium fluoride, namely, 40 and 80 ppm, (LD50 at 96 h: 120 ppm). Acid and alkaline phosphatases, which are significantly associated with the structural and metabolic aspects of tissues, have been examined quantitatively to assess their involvement in the pollutant-induced derangement in the fish. Initial depletion in both these hydrolases paralleled low levels of total proteins in the two target tissues (liver and muscles). These observations in conjunction with the histopathological and metabolic alterations seen in the fluoride-exposed fish confirmed the extent of disturbance caused by this pollutant. However, later signs were evidenced of recovery by enzyme and metabolite concentrations close to those in the preexposure period.
