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

摘要

~(210)Po 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. ~(210)Po activities are considerably higher in spring mussels than in summer samples of the same size, especially in Cesme, Bodrum and Didim. The highest activity (1200 ± 100 Bq kg~(-1) dw) was found in a Cesme sample. Higher ~(210)Po activities were observed in smaller mussels than in larger individuals. The average ~(210)Po massic activities in sediments varied in the range of 20 ± 3 and 144 ± 7 Bq kg~(-1) dw. Izmir Bay exhibited the highest polonium activities in sediments, likely due to specific sedimentation processes and other sediment characteristics.
