Barrier islands of Northwest Florida were heavily oiled during the Deepwater Horizon spill, but less is known about the impacts to the shorelines of the associated estuaries. Shoreline sediment oiling was investigated at 18 sites within the Pensacola Bay, Florida system prior to impact, during peak oiling, and post-wellhead capping. Only two locations closest to the Gulf of Mexico had elevated ...
HREE DIFFERENT newly isolated marine fungi were subjected ........to 18S rRNA gene partial sequence analysis. The resulting sequences showed that the isolates belong to Fusarium solani, Trichoderma viride and Aspergillus niger. The isolates have the ability to utilize some petroleum hydrocarbons such as hexane, motor oil and diesel oil. The tested fungi could grow up to 7 days, especially on me...
Petroleum hydrocarbon contamination of ground water is a significant and often complex problem. The complexity results from the fact that ground-water contamination is a product of soil contamination. Especially with older spills, significant amounts of hydrocarbons can be trapped below the water table. Traditional pump and treat is ineffective because of the low solubility of trapped oily phas...
At present, petroleum hydrocarbon is one of the most serious Abstract: environmental problem. Oil spill occurring accidently in the ocean during transportation or other working places like refineries causes great threat to the flora and fauna existing nearby. Modern methods of remediation such as incineration, land filling, burning, etc. are expensive as well as their byproducts produced are of...
Global demand for petroleum keeps increasing while traditional supplies decline. One alternative to the use of conventional crude oils is the utilization of Canadian bitumen. Raw bitumen is a dense, viscous, semi-liquid that is diluted with lighter crude oil to permit its transport through pipelines to terminals where it can then be shipped to global markets. When spilled, it naturally weathers...
Early explorers to Antarctica built wooden huts and brought huge quantities of supplies and equipment to support their geographical and scientific studies for several years. When the expeditions ended and relief ships arrived, a rapid exodus frequently allowed only essential items to be taken north. The huts and thousands of items were left behind. Fuel depots with unused containers of petroleu...
The application of advanced oxidation processes (AOPs) to the treatment of an effluent contaminated with hydrocarbon oils was investigated. The AOPs conducted were Fe2+/H2O2 (Fenton's reagent), Fe2+/H2O2/UV (Photo-Fenton's reagent) and UV-photolysis. These technologies utilize the very strong oxidizing power of hydroxyl radicals to oxidize organic compounds to harmless end products such as CO2 ...
BACKGROUND The need to control high costs of running operating rooms while providing for timely patient care led us to assess the time wasted in the operating room (OR). METHODS OR use by two general surgery and two orthopedic departments in a metropolitan public hospital were analyzed, and the time elapsed when a scheduled OR remained unused or the patient was still awaiting surgery was meas...
Introduction: The increasing trend of petroleum production in Iran and lack of proper and systematic management of waste products in the deposition of petroleum storage tanks have made the existing hydrocarbons as a major hazards to the environment. In this study, the ozonation process was used to remove the petroleum deposits. Materials and Methods: In this experimental study, effects of pH, ...
Even though petroleum-degrading microorganisms are widely distributed in soil and water, they may not be present in sufficient numbers to achieve contaminant remediation. In such cases, it may be useful to inoculate the polluted area with highly effective petroleum-degrading microbial strains to augment the exiting ones. In order to identify a microbial strain for bioaugmentation of oil-contami...
