Analyse des hydrocarbures et des acides gras dans les sediments superficiels preleves a proximite du rejet des eaux usees de la zone industrielle de la ville d'El Jadida (Cote Atlantique Marocaine)

摘要

Marine sediments collected near the El Jadida industrial sewage (Moroccan Atlantic Coastal) have been analysed in order to determine and to compare the amounts of: extractable organic matter, saturated and aromatic hydrocarbons and fatty acids. The quantitative and qualitative analysis of hydrocarbons(saturated and aromatics) is useful to know the origine of these compounds. Generally, petroleum hydrocarbons are predominant, but biogenic hydrocarbons are also present. The analysis are conducted by capillary gas chromatography, capillary gas chromatography/mass spectrometry and U.V.fluorescence (synchronous excitation) methods.
