摘要: The Mersey estuary is the most contaminated in British waters. Detailed studies are underway on pathology of flounder (Platichthys flesus) from and nearby, but less contaminated, Dee estuary. Flounder breed offshore spend a lot time estuaries, penetrating into freshwater. These flatfish close contact with sediments will be exposed to exenobiotic stored sediments. Plaice (Pleuronectes platessa) which enter tidal flow than likely show evidence pollutant exposure. Over 20 plaice were collected Mersey. Samples liver, kidney gonad fixed 10% formal saline, processed paraffin wax 5 μm sections cut stained haematoxylin eosin. Liver changes consisted variable amounts glycogen/lipid storage product, minor perivenular perivascular fibrosis, helminth parasitisation. No tumours or foci cellular alteration, necrosis inflammation seen. In only consistent normal gonadal cycling was provide that little no toxic pathological damage resulting their stay
