Etude environnementale et sociale du PRAO (Cap Vert, Sierra Léone, Libéria, Sénégal) OceanDocs
Faye, M. M..
La Commission Sous Régionale des Pêches (CSRP), qui est un organisme intergouvernemental de coopération halieutique dont l’objectif global est l’harmonisation à long terme, des politiques des pays membres en matière de préservation, de conservation et d'exploitation durable de leurs ressources halieutiques et le renforcement de leur coopération au profit du bien-être de leurs populations respectives, a obtenu par l’intermédiaire de la Banque mondiale, un Don du Fonds pour l’Environnement Mondial (FEM) et du Gouvernement du Japon, pour la préparation d’un Projet Régional des Pêches en Afrique de l’Ouest (PRAO) pour trouver une solution à la problématique susvisée. Ce projet implique 9 pays côtiers: la Mauritanie, le Cap Vert, le Sénégal, la Gambie, la...

Contaminación por residuo de hidrocarburo del petróleo en el Puerto Marítimo de Guayaquil y su área de influencia debido a actividades navieras, período 1984 al 2004 OceanDocs
Rodríguez Moreira, A..
Siendo Guayaquil el principal Puerto Marítimo y fluvial del Pacífico Ecuatoriano, y de gran importancia del comercio exterior que maneja el sistema portuario nacional, así como las diversas actividades como la exportación: carga refrigerada e importación de materias primas para la industria, se determinó un estudio de evaluación cualitativa y cuantitativa de los derrames eventuales de residuos de hidrocarburos del petróleo ocasionado por las diferentes embarcaciones apoderadas en los muelles de Autoridad Portuaria de Guayaquil.

Evaluation de la contamination chimique par les métaux traces (Cd, Pb, Hg et Zn) du zooplancton et de la sardinelle <Sardinella aurita>dans le golfe de tunis OceanDocs
Ennouri, R.; Chouba, L.; Kraeim, M.M..
La présente étude a pour but de déterminer l’organotropisme de quatre métaux traces (Cd, Pb, Hg et Zn) ainsi que leurs concentrations dans le zooplancton et dans trois organes (muscle, foie et branchies) de la sardinelle (Sardinella aurita) provenant du golfe de Tunis. Les résultats ont montré que les concentrations moyennes des quatre métaux dosés (Cd, Pb, Hg et Zn) sont plus élevées dans la sardinelle que dans le zooplancton. Ceci est dû à la bioamplification de ces éléments dans la sardinelle qui occupe un niveau trophique élevé de la chaîne alimentaire marine. Pour le Pb, le Hg et le Zn, les teneurs le plus élevées ont été enregistrées dans les branchies de la sardinelle, alors que le Cd est concentré davantage au niveau du foie. Les concentrations...

Growth and toxicity tests on the marine nanoplanktonic alga <i>Platymonas tetrathele</i> G.S. West in the presence of crude oil and emulsifiers OMA
Mommaerts-Billiet, F..
Phytoplankton response to environmental pollution by oil and emulsifiers has been studied. The nanoplanktonic flagellate <i>Platymonas tetrathele</i> has been assayed with increasing concentrations of crude oil, industrial non-ionic emulsifiers and mixtures of these products. Cultures poisoned with an emulsifier with an aromatic solvent exhibited a very long lag phase. Diminished growth rates were observed for all the products tested most of the time at concentrations above 50 ppm. The mixtures showed a toxicity close to that of the emulsifier component at its concentration in the mixture and lower than that of the crude oil alone. Fine structure modifications have been investigated and the possible ecological effects of such pollution have...

A case study of ship track formation in a polluted marine boundary layer OMA
Noone, K.J.; Johnson, D.W.; Taylor, J.P.; Ferek, R.J.; Garrett, T.; Hobbs, P.V.; Durkee, P.A.; Nielsen, K.; Öström, E.; O'Dowd, C.; Smith, M.H.; Russell, L.M.; Flagan, R.C.; Seinfeld, J.H.; De Bock, L.; Van Grieken, R.; Hudson, J.G.; Brooks, I.; Gasparovic, R.F.; Pockalny, R.A..
A case study of the effects of ship emissions on the microphysical, radiative, and chemical properties of polluted marine boundary layer clouds is presented. Two ship tracks are discussed in detail. <i>In situ</i> measurements of cloud drop size distributions, liquid water content, and cloud radiative properties, as well as aerosol size distributions (outside-cloud, interstitial, and cloud droplet residual particles) and aerosol chemistry, are presented. These are related to remotely sensed measurements of cloud radiative properties. The authors examine the processes behind ship track formation in a polluted marine boundary layer as an example of the effects of anthropogenic particulate pollution on the albedo of marine stratiform clouds.

The stormwater drain system as a pollution vector of the seashore in Fortaleza (Ceará State, Brazil) BJM
Vieira,Regine H.S.F.; Catter,Karla M.; Saker-Sampaio,Silvana; Rodrigues,Dália P.; Theophilo,Grace N.D.; Fonteles-Filho,Antonio A..
The aim of this study was to make a diagnosis of coastal pollution through bacteriological analysis of water taken from stormwater drain systems and the nearby seashore. The results were submitted to statistical analysis as to differences in the Most Probable Number (MPN) of fecal coliform (FC) found between the stormwater drain systems and adjacent seashore locations both at low and high tides. The main conclusions were: (a) most water samples collected from the stormwater systems presented MPN values for FC above 1,000 per 100 ml; (b) only 20% of the samples from the adjacent seashore presented MPN values for FC above 1,000 per 100 ml, a fact which may be explained by the distance between the drain system outlets and the actual seashore; (c) FC/100 ml...
