Utilisation d’espèces halieutiques exploitées comme indicateurs de la contamination chimique en zone littorale
Provedor de dados: 5
Autores: Abarnou, Alain.
The concept of biological indicator relies upon the assumption that the contamination measured in biological tissues reflects that of the aquatic environment. This study aims to update the knowledge on contamination levels of various chemical contaminants in a few exploited fish species from various areas along the French coastline. The objective of the work is to evaluate the possibility of differentiating the various coastal zones according to the contamination levels measured in fish living there. Several groups of contaminants were followed: PCBs (marker PCBs and dioxin-like PCBs), dioxins (PCCDs and PCDFs), PBDEs, PFCs and total mercury). These contaminants were mainly measured in four fish species: the sea bass (Dicentrarchus labrax), the mackerel...

Climatic trends in continental shelf waters off Ghana and in the Gulf of Guinea, 1963-1992
Provedor de dados: 5
Autores: Koranteng, Ka; Mcglade, Jm.
Using time series analyses, some physical parameters of the continental shelf waters of the Gulf of Guinea were examined. Analysis of coastal sea surface temperatures from Ghana and Ivory Coast, and offshore sea surface temperatures from the Gulf of Guinea clearly shows spatial and inter-annual patterns of cooling in coastal waters of West Africa. The behaviour of the decomposed trend of coastal and offshore sea surface temperatures, sub-surface: temperature measured at 100 m depth off Ghana and salinity showed that the observational period (1963-1992) could be divided into three climatic periods: the period before 1972, from 1972 to 1982, and the period after 1982. In the first period, sea surface temperature at both coastal and offshore areas and bottom...

Surveillance écologique et halieutique des sites de centrales nucléaires littorales : évaluation et perspectives
Provedor de dados: 5
Autores: Quintin, Jean-yves; Bordet, F.
Electricité de France (EDF) has asked Institut Français de recherche pour l'exploitation de la mer (IFREMER) to monitor the coastal marine environment and its living resources around nuclear power plants along the French coast. Started in 1974, these investigations were undertaken in the areas of Gravelines, Le Blayais, Paluel, Flamanville, and Penly; the objective is to detect any impact of the open-circuit water cooling system, as well as any differences in the marine environment itself. To examine this question, IFREMER has set up a program called Impact des Grands Aménagements (IGA). It has evolved according to the results obtained and now integrates the specificity of each site in a global program common to all. The nature and the problems of impact...

Diagnostic de la contamination chimique de la faune halieutique des littoraux des Antilles françaises. Campagnes 2008 en Martinique et en Guadeloupe
Provedor de dados: 5
Autores: Bertrand, Jacques; Abarnou, Alain; Bocquene, Gilles; Chiffoleau, Jean-francois; Reynal, Lionel.
During the years 1972-1993, kepone a persistent pesticide has been used in the banana fields of the French West Indies (Martinique and Guadeloupe) to content a weevil. A slow desorption of the molecule from soil induces its transfer to the sea through the rivers from leaching and erosion. This study intended to take stock on the contamination by kepone of the fishery species around the islands fifteen years after the kepone ban. Furthermore other chemical pollutants were sought in fish and shellfish around the Martinique island.   The results confirmed persistence of marine fauna contamination by kepone, mainly in the alluvium areas in front of polluted rivers. They shown also that this contamination may spread more widely but with fast decreasing through...
