Abstract
This paper presents the results of an investigation from 1980 to 1985 on the content of 210Po in sea water and its accumulation in southern Baltic plankton. The mean value of the 210Po concentration in sea water has been determined to be about 0.5 mBq dm-3, with the proportion of the dissolved forms being ca 80%. It has been proved that 210Po is accumulated by plankton organisms. The mean 210Po concentration factors calculated on the basis of its content in plankton fall within the range from 5×103 to 4.2×104 and increase as follows: phytoplankton<macrozoo-plankton<mesozooplankton. Moreover, differences in 210Po concentration in mesozooplankton collected at the Slupsk Trough and the Gdańsk Basin have been observed. The above differences have been related to intense blue-green alga blooming in the Gdańsk Basin.
