Abstract
Curium ( 244Cm) uptake from contaminated sea water was studied in five benthic marine species: two bivalve molluscs ( Scrobicularia plana and Cerastoderma edule), two polychaete annelids ( Arenicola marina and Nereis diversicolor) and one amphipod crustacean ( Corophium volutator). The concentrations in the whole organisms relative to the concentration in the sea water (concentration factors) were: 700 for the amphipods (after 11 d of accumulation), 140 for the cockles (after 28 d), 80 for the scrobicularia (after 23 d) and ∼30 for the two annelids (after >20 d). All species except S. plana accumulated americium and curium similarly; S. plana accumulated similar amounts of curium and plutonium.
