During 2015, a selection of Mediterranean mussels (Mytilus galloprovincialis) and seawater were sampled along the Slovenian coast, which is part of the North Adriatic Sea, in order to test for the presence of bisphenol A (BPA). The concentration of the BPA in the tissues of mussels sampled from the farms and open sea was from < 0.03 to 0.55 µg kg-1 of w.w. and from < 0.03 to 0.46 µg kg-1 of w.w., respectively. The mussel shells from the farms and open sea contained from 0.01 to 0.3 µg BPA kg-1 of w.w. and from 0.04 to 0.27 µg BPA kg-1 of w.w., respectively. In a harbour, mussel tissue and shell concentration of BPA was 0.21 and 0.18 µg BPA kg-1 of w.w., respectively. The seawater in the shellfish farms and the open sea was contaminated with an average of 0.007 µg l-1 of BPA.
