{sup 137}Cs Distribution in the Northern Adriatic Sea (2006-2010)

Abstract

Artificial radioactivity in the northern Adriatic Sea was assessed by analysis of {sup 137}Cs concentrations in seawater, sediment and marine organisms. A comparison of radioactive contamination was made between different parts of the marine ecosystem including the area of the Po river delta, the protected area of the Lim bay and the Rovinj coastal area in the period from 2006 to 2010. In the area of the Po river delta {sup 137}Cs concentrations in seawater had decreased back to pre-Chernobyl values (2.48 Bq/m), although in sediment they were slightly higher (8.70 Bq/kg). Inside the Lim bay area {sup 137}Cs concentrations in surface water were low (1.93 Bq/m) and, in the mussel Mytilus galloprovincialis, even undetectable in this period. In the Rovinj coastal area {sup 137}Cs concentrations in surface water remained constant (2.23 Bq/m), as well as in the surface sediment (1.88 Bq/kg). {sup 137}Cs concentrations were detectable at very low activity levels in Mugil cephalus and Sardina pilchardus. The data indicate that some species such as the intertidal brown algae Fucus virsoides and the benthic fish Mullus barbatus are better bio-accumulators of {sup 137}Cs than others. These species should be used as bio-indicators in future monitoring schemes in the A  More>>
