✦ Synopsis

This paper presents the results of an investigation from 1980 to 1985 on the content of 2X~ in sea water and its accumulation in southern Baltic plankton. The mean value of the 21~ concentration in sea water has been determined to be about 0.5 mBq din-% with the proportion of the dissolved forms being ca 80%. It has been proved that 2~~ is accumulated by plankton organisms. The mean 2~~ concentration factors calculated on the basis of its content in plankton fall within the range from 5 x 103 to 4.2 x 104 and increase as follows: phytoplankton< macrozooplankton < mesozooplankton. Moreover, differences in 21~ concentration in mesozooplankton collected at the S~upsk Trough and the Gdafisk Basin have been observed. The above differences have been related to intense blue-green alga blooming in the Gdafisk Basin.
