Acute and subchronic toxicity of aflatoxin B1 to rohu, Labeo rohita (Hamilton).
Pathological alterations in various organs of rohu (L. rohita) fingerlings following acute (0, 7.50, 11.25 and 13.75 mg/kg body weight) and subchronic (0, 1.25 and 2.50 mg/kg body weight) single i.p. aflatoxin B1 exposure for 10 and 90 days, respectively, were investigated. Mortality (dose-dependent) was marked only during acute toxicosis. The changes observed in various organs were dose and ti...

متن کاملA Study on the Toxicity of Chromium on the Histology of Gill and Liver of Freshwater Fish Labeo Rohita
The toxic effect of chromium on the histology of gill and liver of Labeo rohita fingerlings was studied. The fingerlings were exposed for 10, 20 and 30 days in 10% sublethal concentration of 96 h LC50 of chromium (3.5 ppm). The gills exposed to sublethal concentration of chromium showed mild histological alterations during 10 days of exposure. However after 30 days, fusion of gill lamellae, hyp...
