    Contamination par le 51Cr et le 109Cd de cultures de l'algue Dunaliella bioculata (1975)

    Notes: Abstract Contamination of Dunaliella bioculata by 51Cr and 109Cd was observed experimentally to determine the possible uptake mechanisms of the metals by this alga. Despite slight contamination by 51Cr, it was not possible to demonstrate any active mode of absorption of the radionuclide. In the case of 109Cd, however, the various tests revealed that uptake did occur, the concentration factor being about 300 for a contact time of 15 days with this element.

    Etude préliminaire, in situ, de la distribution du plutonium dans différents tissus et organes de Cancer pagurus (Crustacea: Decapoda) et de Pleuronectes platessa (Pisces: Pleuronectidae) (1976)

    Notes: Abstract Plutonium distribution was preliminary investigated in tissues and organs of the crab Cancer pagurus and the plaice Pleuronectes platessa collected inshore near the La Hague fuel reprocessing plant (France). There is an important transfer of plutonium from sea water to the gills and exoskeleton of the crab, these organs representing a large surface adsorption. In the plaice, only the gut strongly accumulates plutonium, indicating contamination by feeding. The edible parts of these two marine species, particularly the flesh, do not constitute, for man, an important source of contamination by environmental plutonium.

    Etude comparée des teneurs en plutonium chez divers mollusques de quelques sites littoraux français (1977)

    Notes: Abstract Plutonium contents of various species of molluscs sampled from several sites along the French coast were measured in order to reveal any distributional patterns of the plutonium levels. The influence of the La Hague nuclear fuel reprocessing plant was apparent in the immediate proximity of the waste-disposal outfall (Ecalgrain Bay), and to a lesser degree in an oyster farming center situated about 50 km east of the Bay of Ecalgrain (St. Vaast-la-Hougue). Plutonium concentrations in molluscs from the remaining sites were quite comparable to levels that have been measured in similar species subject only to plutonium derived from atmospheric fallout. All molluscs, except those from Ecalgrain Bay, displayed higher levels of plutonium in the shell than in the soft parts, a finding in agreement with similar studies which have been reported recently. However, those individuals sampled from the vicinity of the outfall consistently displayed shell: soft parts plutonium ratios of less than 1. This difference may reflect different physico-chemical forms of this isotope present at the different sampling stations. With the exception of Crepidula fornicata shell, the tissues of filter-feeding molluscs do not appear to concentrate plutonium above the level found in other types of molluscs.

    Description / Table of Contents: Résumé 1. L'étude de la décontamination de deux espèces de poissons marins (Mugil chelo Cuv. et Blennius pholis L.) préalablement contaminés par le 137Cs, fait apparaître deux phases distinctes d'élimination: une première rapide, une seconde à évolution lente. 2. La période biologique correspondant à la phase d'élimination rapide est de 20 à 30 jours pour les deux espèces. 3. Les périodes biologiques correspondant à la phase lente du phénomène sont de 154 jours pour M. chelo et 203 jours pour B. pholis.
    Notes: Abstract Study of the decontamination of two species of marine fishes (Mugil chelo Cuv. and Blennius pholis L.) contaminated by 137Cs reveals two distinct elimination stages: one fast, the other slow; the corresponding biological half-lives have been determinated: for the fast stage it ranges from 20 to 30 days for both species; for the slow stage it is 154 days for M. chelo and 203 days for B. pholis.
