AbstractAbstract
[en] The feasibility of developing natural dispersants (biodispersants) for use in response to a marine oil spill was discussed. In this study biochemical tests were conducted with Bacillus and Coccus Gram Positive bacteria in order to select the one marine microorganism which is capable of producing biodispersants to degrade crude oil. Different carbon sources and salt concentrations were used in the experiments. A second experiment was conducted in which the production of biodispersants by the pure microbial strain were studied by measuring interfacial tension, determined by using the Longman method. The surfactant efficacy and the dispersant stability of Arabian Light crude oil was also studied. The biological oxygen demand at five days, biological oxygen demand at the end of the biodegradation, the biodegradation constant and the biochemical stabilization constant were determined during the degradation process. 23 refs., 9 tabs.,4 figs

AbstractAbstract
[en] The physical and chemical properties of Pina crude oil are analyzed, and the evaporation of this same crude oil spilled at sea and on calcareous type beach sand is described. The properties were analyzed for future uses in simulations of oil spills at sea. Among the parameters used in the characterization are specific gravity, viscosity, flash point, hydrocarbon groups, sulphur content, distillation, and interfacial and surface tension. In the evaporation process, the influence of layer thickness of crude oil and the influence of the height of the air chamber for the same thickness of crude oil at different wind velocities and conditions was of particular interest. The evaporated fraction was also correlated with the time and qualitative and quantitative variation of the components of the crude oil were studied by gas chromatography. The maximum per cent of evaporation over a 28 day period was 39 per cent at sea and 35.4 per cent when the same crude was spilled on sand. 5 refs., 6 figs

AbstractAbstract
[en] Creation of a geographic information system (GIS), connected to the OILMAP simulation model, and specific for the Balearic Islands is described. The resulting GIS includes information about the coastal areas of the islands, indicating the most sensitive areas (fisheries, natural parks, beaches and their sand type, dimensions, potential occupancy and services). The natural parks bordering the littoral region of the Balearic sea (in Majorca, Menorca, Formentera and Cabrera) are classified by extension, flora and fauna and other characteristics. Data concerning the tanker routes that pass through the Balearic Sea are entered. With the aid of the computer program OILMAP (developed by Applied Science Associates) different types of tanker oil spills are simulated to evaluate the potential risk zones and the effects that an oil spill could create for the Islands
