Distribution of (137)Cs in the Mediterranean mussel (Mytilus galloprovincialis) in Eastern Black Sea Coast of Turkey

Mar Pollut Bull. 2016 Jun 15;107(1):402-407. doi: 10.1016/j.marpolbul.2016.03.032. Epub 2016 Mar 25.


This study presents the results of (137)Cs and (40)K radionuclide concentrations in mussel (Mytilus galloprovincialis) samples collected during the period of February-November 2014 from twelve different stations within the border of the eastern Black Sea region of Turkey. Also, these radionuclide concentrations were determined in sea water and sediment samples. The activity concentrations in seawater, sediment and mussel tissue samples were between 1.12-1.69mBqL(-1), 3.26-30.74 and 1.61-3.16Bqkg(-1) for (137)Cs and 231.41-399.49mBqL(-1), 215.71-450.07 and 286.84-382.16Bqkg(-1) for (40)K, respectively. These values are also in accordance with the concentrations reported for similar regions. Additionally, radiological impact parameters such as daily intake of (137)Cs and (40)K, annual committed effective dose and carcinogenic risk due to the consumption of mussel were calculated and compared with the international data. Lifetime cancer risk values are lower than the limit of 10(-3).

Keywords: (137)Cs; (40)K; Black Sea; Daily intake dose; Mussel; Sediment.
