The aim of this study was to describe the chemical and histomorphological findings in six Barbus barbus, six Ciprinus carpio, six Carassius carassius from a river of Calabria. All the exemplary were fished alive. Besides three Carassius auratus from commercial activity were utilized like control. In subjects taken by the river severe lesions were found in the gills and liver. These histological alterations were associated to high level of zinc too (300 ÷ 350 mg/kg of sample, compared to controls which had values of 50 ÷ 60 mg/kg of sample). The results show the need for continued monitoring of this element on the different environmental matrices, and in order to limit the effects on organisms that led to biomagnification up the food chain, of which man represents the summit.

In subjects taken by the river severe lesions were found in the gills and liver. These histological alterations were associated to high level of zinc too (300 ÷ 350 mg/kg of sample, compared to controls which had values of 50 ÷ 60 mg/kg of sample).
