Etude du Vieillissement d'un Petrole Brut Repandu a la Surface de l'eau de mer dans des Conditions Naturelles

摘要

Photooxidation plays an important role in the weathering process of a petroleum product spilled in the marine environment. Photooxidation generates polar compounds exhibiting a more or less marked surfactant nature. Likewise, photooxidation increases the amount of organic compounds into the water column by the formation of hydrophilic oxidized compounds. In this study, an Arabian Light crude oil (1 litre) was spread on the surface of unrenewed seawater (320 litres) and was subjected to natural irridiation for 70 days. During this time, five samples of the underlying water were taken as well as five samples of the supernatant oil.
