210 Po in sea fish, mussel, algae and beach sediment samples collected at four selected stations (Sile, Trabzon, Sinop and Zonguldak) along the Turkish coast of the Black Sea are presented and discussed. The observed 210 Po massic activities in beach sediments and algae were 5.9–79 Bq kg -1 dry weight (dw) and 11.5–35 Bq kg -1 dw, respectively. The 210 Po levels in fish were between 0.8 and 2.4 Bq kg -1 wet weight (ww) in whiting ( Merlangius sp. ), 1.6–8.9 Bq kg -1 ww in horse mackerel ( Trachurus sp. ), and 5.8–6.3 Bq kg -1 in red mullet ( Mullus sp. ). Possible causes of these variations are “vital effects”, e.g. individual fish size and interfamily differences. The average activity of 210 Po in mussels with shell length ⩾ 5 cm was 25 ± 10 Bq kg -1 ww. |
