Abstract

The aim of this work was to determine the toxicity of ethanol in an aquatic system by means of bioassays with Oreochromis mossambicus (Peters) as a test organism. The study revealed changes in the gill ATPase activities. The results obtained indicated that ethanol brought about a decrease in the body weight, followed by significant inhibition on total ATPase, Na+/K+ ATPase, Ca2+ ATPase and Mg2+ ATPase activities. The studies also indicated that these can be employed as suitable biomarkers in ethanol related toxicity studies.
