Apports et distribution des résidus organochlorés à haut poids moléculaire dans la rade de Brest (milieu marin semi-fermé) ArchiMer
Marchand, Michel; Caprais, Jean-claude; Cossonmannevy, Ma; Moriniere, P.
The aim of this work is to study the input, transfer and distribution processes of chlorinated insecticides (lindane, DDT) and PCB residues in a semi-closed coastal marine environment. Measurements are made in sea water, rain water and sediment samples. Distribution coefficients between sea water and sediment are determined for several organochlorine insecticide and PCB compounds. The results show an important transfer of chlorinated residues from the atmosphere to the marine environment. The highest residue levels in the sediments are observed near other urban and industrial pollution sources. Analyses of mussels show that this mollusc can be used as a biological indicator of sea water pollution. Concentration factors are determined for lindane,...

Facteurs de mortalité observés chez les tortues marines dans le golfe de Gascogne ArchiMer
Duguy, R; Moriniere, P; Le Milinaire, C.
Factors of mortality in marine turtles near the French coast of the Bay of Biscay have been recorded for four species: leatherback (Dermochelys coriacea), loggerhead (Caretta caretta), Ridley's turtle (Lepidochelys kempii) and green turtle (Chelonia mydas). Most accidental captures of D. coriacea by fishing gears lead to drowning, but the main threat for the species is the ingestion of floating waste. Plastic bags induce occlusion or lesions in the stomach and subsequent death. For C. caretta, L. kempii and C. mydas, the pathology points out mainly two features: external or internal mycosis.

During 2004, Caranx crysos and Echeneis naucrates are caught in the Bay of Biscay, at north of their known repartition. The capture in our waters of two specimens of Cyttopsis rosea, the eighth specimen of Trachinotus ovatus and six Lagocephalus lagocephalus are mentioned. NOT CONTROLLED OCR
