Bioaccumulation of gamma emitting radionuclides in red algae from the Baltic Sea under laboratory conditions

The bioaccumulation ability of radionuclides 51 Cr, 54 Mn, 57 Co, 60 Co, 65 Zn, 85 Sr, 109 Cd, 110m Ag, 113 Sn, 137 Csand 241 Amintworedalgaespeciesfromthesouthern Baltic Sea –Polysiphonia fucoidesandFurcellaria lumbricalis– was determined under laboratory conditions. P. fucoides demonstrated better bioaccumulative propertiestowardsmostoftheinvestigatedradionuclides. Asaresult,P. fucoides canberecommendedasagoodbioindicatorofradioactiveenvironmentalpollution. The bioaccumulation of radionuclides in F. lumbricalis was studied during an extended laboratory experiment. The initial extensive uptake of radioisotopes was followed by the rapid removal of cations; in general, concentrations tended to decrease with time. 137 Cs displayed a different behaviour, its concentration in the algae increasing over time mainly due to its large ion radius; this is a factor thatcouldberesponsibleforthestrongermechanicalandchemicalbondingofCs + andthatcouldhamper themovementofionsinbothdirections.
