Accumulation of /sup 60/Co by freshwater plants under natural conditions
The study of /sup 60/Co accumulation by aquatic plants is of interest in finding effective bioindicators for radioactive pollution of nuclear power station cooling ponds. In this respect, /sup 60/Co accumulation was studied in four species of higher aquatic plants most commonly found in the Urals: water thyme (Elodea canadensis), hornwort (Ceratophyllum demersum), lesser duckweed (Lemna minor), and fennel pondweed (Potamogeton pectinatus). The /sup 60/Co accumulation coefficients in the plants studied reached considerable values. The data obtained demonstrate that plants such as hornwort and water thyme with /sup 60/Co accumulation coefficients of 33,500 and 21,500, respectively, may be recommended as bioindicators for these radionuclides in the water bodies polluted with radioactive cobalt.
