The behaviour of ⁵⁹Fe in marine microhabitat

Under the artificial condition the ⁵⁹Fe morphology in sea water, its concentration in sediment and phytoplankton, its distribution and metabolism in tissue organs of marine animals were studied.The results showed that the morphology of ⁵⁹Fe was in a particulate state in sea water.The adsorption rule of ⁵⁹Fe by three kinds of sediments was similar.The concentration ability of ⁵⁹Fe by phytoplankton was very strong.The critical concentration organs of ⁵⁹Fe by marine animals were viscera.The gross radioactivity of ⁵⁹Fe was mainly concentrated in protein.The concentration factor of ⁵⁹Fe by DNA was the highest one.After excretion experiment, ⁵⁹Fe of all the tissue organs was not detected.Small part of⁵⁹Fe remained in the organic acid and protein state.There was a redistribution process in sediment for⁵⁹Fe.
