Antarctic fish Trematomus bernacchii as biomonitor of environmental contaminants at Terra Nova Bay Station (Ross Sea)
Polychlorinated biphenyls (PCBs, including three highly toxic non-ortho coplanar PCBs, IUPAC Ns. 77,126 and 169), polycyclic aromatic hydrocarbons (PAHs), pesticides and trace metal concentrations were determined in the Antarctic fish Trematomus bernacchii collected off the Baia Terra Nova station (...
