Bio-accumulation of<sup>210</sup>Pb and<sup>210</sup>Po within the Trophic Level of Phytoplankton-Zooplankton-Anchovy-Mackerel in the Coastal Water of the Jeju Island, Korea

The activity concentrations of Po were determined in plankton and selected species of macroalgae, crustaceans, molluscs, and fish from Korean coastal waters to understandPo distribution in these trophic levels and to assess the effective dose of Po from seafood ingested by the average Korean. The activity concentration ofPo in macroalgae, mixed plankton, anchovy (whole body), abalone muscle, and abalone viscera was 0.97-1.43, 32-137, 59-392, 2.93 ± 0.86, and 1495 ± 484 Bq kg (w.w.), respectively. Polonium-210 concentration in the whole flesh of mussel and oyster were 47.8 ± 5.9 and 45.3 ± 7.1 Bq kg (w.w.), respectively. Polonium-210 concentration in the muscle of the five tested species of fish other than anchovy ranged from 0.51 to 5.56 Bq kg (w.w.), with the lowest amount in a demersal species. In fish, Po activity concentration was as much as three orders of magnitude higher in viscera than in muscle. The average annual effectivePo dose per average Korean adult, who consumes 42.8 kg of seafood a year (excluding anchovy), was estimated to be 94 μSv y, with 42-71% of this attributed to shellfish. Further studies are required to assess the dose of Po from anchovy owing to its high activity concentration and the manner in which anchovy is consumed.
