Abstract
The biochemical toxicity of arsenic trioxide (AsIII) in a freshwater edible fish Channa punctatus has been studied on exposures ranging from 7 to 90 d. The arsenic concentration increased exponentially in liver, kidney, gills, and muscles of fish up to 60 d of exposure to arsenic. However, arsenic concentration in these tissues declined at 90 d of exposure. This relationship between period of exposure and concentration of arsenic in selected tissues suggests an adaptive response of fish to arsenic. Furthermore, exposure to arsenic-induced lipid peroxidation in these organs increased initially at 7 d of exposure; however, it decreased up to 60 d of exposure but increased again at 90 d of treatment. Values of reduced glutathione (GSH) reflected the observations of lipid peroxidation. The role of GSH in this adaptive response has been discussed.
