Toxicity studies on black molly, Poecilia sphenops against chromium trioxide

Abstract

Alteration of biochemical profiles of muscle tissues in chromium trioxide in the ornamental fish Black molly was investigated after exposure to five acute concentrations of chromium trioxide (80, 100, 110,120, 140 mg/l with control and 110.79 ppm of the 96hrs LC50) for 4 days and sub lethal level exposures were maintained as 5, 10, 20, 40, and 60 mg/l (5th, 10th, 15th, 20th, 25th and 30th respectively) with control for 30 days. The results showed that the total biochemical content decreased with increased duration of exposure as well as increase in concentrations of chromium trioxide for four days in acute study period. All the sub acute concentration exposures gradually increase the biochemical contents throughout study period. The consequences of decrease in the fluctuating biochemical levels and compared with control. The gradual decreases were recorded in the biochemical content for the chromium trioxide effects and also highly significant in the entire sub acute levels. It concludes, the metal induced alterations may probably affect the biochemical profile of the fish.
