Abstract

The main causes of oil pollution in the oceans are extraction of oil, transportation with ballast water release, tanker accidents and also war-related incidents. The spills are particularly destructive for local wildlife and plant life when they get close to shorelines. They also damage boats, fishing gear and harbor installations and greatly diminish the value of the shore as recreational resources. Many, methods have been used to remove oil spills from water including physical removal of CRUDE OIL, chemical remediation of the spills using DISPERSANTs and so-called "sinking agents," and, in some cases, intentionally burning floating petroleum slicks. Using chemical DISPERSANTs as an oil spill countermeasure is the most frequently employed clean-up method because such liquids can be readily applied to large oil spills also this method is generally more cost-effective than physical remediation methods. On the other hand the exclusive property of these DISPERSANTs to make oil spills dispersed into water will enhance the biodegradability of CRUDE OIL due to the increased exposed surface of the spills to such agents. Nevertheless, II surfactant compositions are efficient in dispersing spilled oil products and many of the effective ones the drawbacks of being toxic and/or not biodegradable. PERSIAN GULF is recognized as the world's largest source of fossil fuels and thus enshrining its importance as the world's most strategic waterway. The result of extensive marine traffic is a high risk of oil pollution, both intentional and accidental. To diminish risk ore environmental pollution, use of highly biocompatible DISPERSANTs has been recommended. In this paper, we study biodegradability and the impacts of three DISPERSANTs; Pars I, Pars2 (produced by Iranian lore Oil Company) and Gamlen on degradation of CRUDE OIL in Siri Island water. Biodegradability of Gamlen and its effects on dispersing of oil had been already studied and it is being used in PERSIAN GULF " Here, we present the most dispersing, effective and biodegradable component for dispersion of crude Siri Island water.
