Induction of MFO Activity in the Antarctic fish Pagothenia bernacchii
The aim of this study was to determine the detoxication capacity and the sensitivity to pollutants of fish living in a pristine environment such as the Antarctic Ocean. Forty specimens of Pagothenia bernacchii collected during the Antarctic summer of 1991-92 were divided into three groups, and were...
