摘要：Keratosis, skin cancer and neurological disorder in human and experimental animals are among the most commonly observed health effects associated with acute and chronic exposures to inorganic arsenic. This study examines the acute and chronic dose-responses of arsenic trioxide on Poecilia sphenops (Black Molly). P. sphenops has been reported as a highly adaptable species and robust in nature. It has been extensively used to evaluate toxicity of many pollutants due to their high growth rate, birth size, reproduction and brood number. In current investigations, a batch experiment was conducted under control conditions to assess the effect of As2O3 on Black Molly. Lethal concentration (LC50) of As2O3 were investigated and observed to be 49.5 mg/L. Growth performance, macroscopic observation and mortality of fingerlings of P. sphenops in experimental tank containing 1 mg/L of As2O3 was monitored for 60 days. Mortality of fishes in the experimental tank was observed to be ~20% after 60 days of incubations. Significant change in morphometric, behavior and diminution in growth performance were observed. These results evidently indicate the sensitivity of Black Molly towards As2O3.
