| L'objectif principal du Réseau National d'Observation de la qualité du milieu marin (RNO) est l'appréciation des niveaux et tendances de certains contarninants, organiques et métalliques, dans le milieu marin. Ce rapport dresse le bilan de 10 ans de surveillance par le RNO, de tout le littoral normand. Les paramètres retenus pour cette étude sont : le cuivre, le plomb, le zinc, le cadmium, pour les métaux, les PCB, les HAP, les aHCH et yHCH, le DDT et ses métabolites, pour les composés organiques. L'étude de l'évolution des teneurs montre que les métaux ont tous une tendance à la hausse, tandis que les composés organiques sont tous en baisse. On constate également que l'estuaire et la baie de Seine constituent l'ensemble côtier français le plus contaminé... |

| Top predators like marine mammals have been intensively used for monitoring the contamination of the marine environment, particularly in industrialized coastal areas of the Northern Atlantic Ocean. Such data concerning contamination in the Southern hemisphere are very scarce. Samples were taken in the fatty protuberance of the forehead (melon) from eleven Commerson's dolphins (Cephalorhynchus commersonii, Lacépède, 1804) caught in the coastal waters of the Kerguelen Islands (Southern Indian Ocean). They were analyzed for DDT, PCB and HCB, using capillary gaz chromatography. The levels of contamination [DDT= 1 150 ± 650, PCB = 1 150 ± 770, HCB=500±300ng/g of extracted matter (lipids)] are between ten and a hundred times Jess than those found in similar... |

| Biological responses and contaminant levels in biological tissues were investigated in fish specimens of grass goby (Zosterisessor ophiocephalus) collected in spring 2000 in a moderately polluted brackish ecosystem, the Orbetello lagoon (southern coast of Tuscany, Italy). The complexity of harmful effects that contaminants may cause in fish over time was assessed. General condition indices (somatic liver index, and gonadal somatic index), cytochrome P450 enzymes, acetylcholinesterase activity and ovarian morphology were integrated with the content of organochlorines (OCs-hexachlorobenzene, DDTs and polychlorinated biphenyls) in liver and ovaries and p-nonylphenol (NP) and lower ethoxylate (NPE(1-2)) content in muscle and ovaries as well. Samples collected... |
