초록 | The activity concentrations of $^{210}Po$ and $^{210}Pb$ within phytoplankton-zooplankton-anchovy-mackerel in the coastal water of the Jeju Island were determined to understand their distribution and bio-accumulation along the trophic level. In the surface water, the total activity concentrations of $^{210}Po$ and $^{210}Pb$ were $0.83{ pm}0.004mBq ;kg^{-1}$ and $1.27{ pm}0.03mBq ;kg^{-1}$ . And the dissolved activity concentration of $^{210}Po$ and $^{210}Pb$ were $0.75{ pm}0.06mBq ;kg^{-1}$ and $1.22{ pm}0.09mBq ;kg^{-1}$ respectively. In the phytoplankton, the concentration factor (CF) of $^{210}Po$ and $^{210}Pb$ were $1.5{ times}10^5$ and $2.6{ times}10^4$ shows $^{210}Po$ is 5 times higher compared to $^{210}Pb$ . The similar CF factor in the zooplankton of $^{210}Po$ was derived as $1.4{ times}10^5$ . The CF of $^{210}Po$ in anchovy was increased twice compared to that in plankton. This is the evidence that there is $^{210}Po$ bio-magnification in the trophic level of plankton-anchovy. However the $^{210}Po$ activity concentration in the muscle tissue of mackerel was one-hundred times lower than that in anchovy. This reflects that in the trophic level of anchovy-mackerel, the bio-accumulation of $^{210}Po$ is decreased. The activity concentrations of $^{210}Po$ in the internal organs of anchovy and mackerel were 8 to 38 times higher than those in muscle tissues. In phytoplankton-zooplankton-anchovy, the CF of $^{210}Pb$ was decreased five times along the trophic level in order. In anchovy-mackerel it was decreased by 30-70%. |
