ports’ activities could result in oil spills occurrences and oil pollution in different ways including the discharges of ships’ oily wastes, discharges of oily ballast water and leaks at oil terminals. in this paper, using the results of the analyses of the hydrocarbon compounds in the samples collected from the sediments in the anzali port in the caspian sea in iran, the levels of oil pollutio...

The authors attempted to determine if the organic sulfur compounds usually contained in a crude oil could serve as a marker of oil pollution in fish. Eels (Anguilla Japonica Temminck et Schlegel) were maintained in a controlled laboratory environment of water with a suspension of crude oil. Gas chromatography-mass spectrometry and mass chromatography of eel flesh extract showed the presence of ...

Oil pollution is one of the main pollutions marine environment. With year-on-year increase our country's oil imports and maritime transportation, offshore has become more serious, causing serious harm to ocean nearshore According current situation pollution, article outlines situation, sources, hazards methods currently used deal with prevent in physics, chemistry biology.

Selective filtration of gas, water, and liquid or gaseous oil is essential to prevent possible environmental pollution and machine/facility malfunction in oil-based industries. Novel materials and structures able to selectively and efficiently filter liquid and vapor in various types of solutions are therefore in continuous demand. Here, we investigate selective gas-water-oil filtration using t...

INTRODUCTION The environmental concerns, including dwindling crude oil resources, high oil prices, pollution, greenhouse CO2 emissions, and toxicity in the environment, married to societal pressures towards sustainable development are currently making countries around the world turn to biomass as a renewable resource for a variety of products: fuels, lubricants, chemicals, polymers, fibers, neu...

Claude ZoBell’s recognition of the influence of microorganisms in the ecology of petroleum bearing environments was all encompassing. This translated into a unique contribution over the entire span of the oil industry. Many of his publications in the 1940s and 1950s discussed the key role of microorganisms in the diagenesis of hydrocarbon products. At a time when the industry was treating the s...
