137Cs distribution in the northern Adriatic Sea

Anthropogenic radioactivity in the northern Adriatic Sea was assessed by analyzing 137Cs activity concentrations in seawater, sediment, and marine organisms in the period from 2006 to 2010. The investigated locations were the Po River delta, Lim Bay and the Rovinj coastal area. At all locations 137Cs activity concentrations in seawater were lower than pre-Chernobyl values (< 4 Bq m-3). The highest 137Cs activity concentrations in sediment were found in the Po River delta (8.70 Bq kg-1). The data indicate that some species, such as sardine Sardina pilchardus, red mullet Mullus barbatus and the brown alga Fucus virsoides are better bioaccumulators of 137Cs than others. In addition, the ERICA Assessment Tool was used to calculate the total dose rates for reference organisms included in the software, as well as for specific sampled marine organisms.
