Acute toxicity I: effect of profenofos and triazophos (organophosphates) and carbofuran and carbaryl (carbamates) to Labeo rohita.
Profenofos and trizaophos (organophosphates) carbofuran and carbaryl (carbamates) are among the major toxicants polluting freshwater bodies, as well as exerting a significant effect on the health of fish. In this study, the 96 h LC50 of the most commonly used organophosphates and carbamates was determined in one of the indigenous fish species, Labeo rohita fingerlings. Pesticides were applied to fingerlings that had been grown under optimized standard conditions under a maintained static bioassay system. Probit analysis was used for the determination of LC50 values, which were ascertained as 6.64, 0.32, 1.4, and 8.24 mg/L for triazophos, profenofos, carbofuran, and carbaryl, respectively. Acute toxic stress was noted with fish exhibiting behavioral toxicity including suffocation, lying on the bottom, erratic swimming, lethargy and downward movements, and gulping prior to mortality.
