  Abstract: Acute toxicity of Cr (VI) (as K2Cr2O7) to freshwater stinging catfish, Heteropneustes fossilis and its histopathological impacts on gill and liver tissue were evaluated. Fish showed behavioral alterations after K2Cr2O7 exposure and 96 h-LC50 was 35.724 mg/L in static bioassay. Fish were exposed to three sub-lethal concentrations (concentration I=1/4th of 96 h-LC50, concentration II=1/10th of 96 h-LC50 and concentration III=environmental concentration of Cr reported in the river Buriganga). Blood, liver …
