Accordingly, TBT concentrations female varied from 43 250 ng Sn/g dry weight 2011, which a maximum Nevertheless, results for degradation index suggest that there have been recent inputs within main harbours. Overall, legislative measure is contributing reduction effects although its presence still evident.
