HPLC analysis of 16 polycyclic aromatic hydrocarbons (PAHs) in the flesh demonstrated that PAHs accumulation in the treated snails was fluctuated with time. The accumulation is due to their biotransformation process during metabolism. The histopathological observations of the...

Fish from different species has diverse ecological needs and respond differently to the environmental stress conditions. Thus, the sensitivity, bioaccumulation and antioxidant capacities of three major carps Catla catla, Labeo rohita and Cirrhina mrigala towards metals mixture (Cd+Cr+Cu+Pb) were determined during present research work. Sensitivity of the thr...
