Etude comparative des methodes d'analyses de la contamination petroliere dans l'environment marin. 1. Etude fluorometrique.
Provedor de dados: 5
Autores: Awad, Hassan.
Although the determination of hydrocarbons in the marine environment is based usually on the same analytical steps, organic solvents extraction, column chromatography purification, and means for hydrocarbons detection and identification, the variations in the equipment and solvent systems included in the different established techniques hinder to obtain a global idea about the oil contamination state of the seas. Many authors and conferences declared the necessity of carrying out a comparative study on the efficiencies of the various published analytical techniques in this field. According to the facilities available in the laboratory, 25 applications of 16 published techniques were applied on a fixed weight of unique sample of sediments, mussels, fishes,...

Accumulation and depuration of hydrocarbons in the mangrove oyster Crassostrea rhizophorae
Provedor de dados: 5
Autores: Delcastillo, C; Corredor, J; Morell, J.
Adult specimens of Crassostrea rhizophorae were exposed to diesel oil dispersed in seawater. The experiment consisted of a 10 days contamination period and 15 days depuration period. Oyster samples were extracted, and analysed by gas chromatography and UV fluorescence spectroscopy. The concentrations of n-alkanes, branched alkanes, unresolved complex mixture (UCM) and aromatic hydrocarbons were determined. The oysters accumulated the hydrocarbons rapidly, reaching a maximum concentration of 387.5 ug/g (wet weight). After exposure to uncontaminated seawater, the oysters were able to reduce their hydrocarbon load to 5.6 ug/g. The data indicates that C. rhizophorae is capable of preferential accumulation and depuration of hydrocarbons. Apparently, the oysters...
