Activity levels of 210Po and 210Pb in some fish species of the Izmir Bay (Aegean Sea)

PubMed ID: 23131198Concentrations of 210Po and 210Pb were determined in the edible muscle tissue of twelve species of marine fish collected from Izmir Bay in the Aegean Sea Region of Turkey during the 2006-2007. 210Po activity concentrations in fish samples were found to vary from ND to 400±9Bqkg-1 dry weight and 210Pb activity concentrations were found to vary from ND to 15±3Bqkg-1 dry weight. The highest dose contribution due to 210Po to humans was found to be 8.908µSvy-1. © 2012 Elsevier Ltd.2006/NBE/001This research work is supported by Grants from Ege University Institute of Nuclear Sciences Contract No. 2006/NBE/001 . -

210Po in mussels (Mytilus galloprovincialis) and sediments along the Turkish coast of the Aegean Sea

210Po results for mussels (soft tissue) and sediment samples from 9 stations along the heavily industrialized Turkish coastal zone of the Aegean Sea are presented and discussed. The mean massic activities in mussels varied between 190 ± 10 and 830 ± 40 Bq kg-1 dry weight (dw). The results show significant differences in concentrations for similar size mussels collected at different sites. 210Po activities are considerably higher in spring mussels than in summer samples of the same size, especially in Çeşme, Bodrum and Didim. The highest activity (1200 ± 100 Bq kg-1 dw) was found in a Çeşme sample. Higher 210Po activities were observed in smaller mussels than in larger individuals. The average 210Po massic activities in sediments varied in the range of 20 ± 3 and 144 ± 7 Bq kg-1 dw. İzmir Bay exhibited the highest polonium activities in sediments, likely due to specific sedimentation processes and other sediment characteristics. © 2006 Elsevier Ltd.
