Acute effect of mercury toxicity on some enzymes in liver of teleost Sarotherodon mossambicus.
The effects of 1.5 ppm of mercuric chloride (LC50/48 hr) on some enzymes and organic substances of liver tissue of Sarotherodon mossambicus were studied. Significant decreases in the activities of succinate dehydrogenases, lactate dehydrogenases, glucose-6-phosphate dehydrogenase, alkaline phosphatase, and acid phosphatase and in the levels of organic substances like total anthrone-positive substances, glycogen, and total ninhydrin-positive substances were observed. The results indicate impaired oxidative and transphosphorylative activities and utilization of carbohydrates during acute mercury toxicosis in fish.
