Abstract Crude oil frequently contains stable radicals that allow detection by means of EPR spectroscopy. On the other hand, most sands and soils possess significant amounts iron, manganese or metallic species often provide excessively broad signatures combined with well-defined sharp features quartz defects. In this study, we demonstrate feasibility to identify contamination in natural environ...

The Niger Delta is located in Southern Nigeria and is Africa’s largest delta, covering about 70,000 square kilometers, and with about one-third of it made up of wetlands, and the third largest world mangrove forests. The Niger Delta is unique in Nigeria because it is the home of Nigeria’s oil industry, with its attendant environmental hazards such as water, land, air pollution, etc. Human activ...

Crude oil is not a specific single mineral substance. It is often called petroleum hydrocarbon because of its predominant make up of carbon and hydrogen, though it sometimes contains other elements1. There are many types of crude oil having widely different properties. Such variability are related to their behaviour and even degradation on spillage. Crude oil can however be divided into two: he...

This paper presents an algorithm for spots detection in Synthetic Aperture Radar (SAR) images that can be used to support environmental remote monitoring. Monitoring areas with high frequency of oil spillage by accidental or illegal oil discharges can prevent marine damage spreading. But the presence of speckle noise in SAR images limits the visual interpretation of scenes because it obscures t...

An increasing awareness of environmental issues, coupled with a number of recent events, has focused considerable attention on the likely consequences of a large oil spill. If the impact of these accidental releases is to be minimises, the risk assessment and contingency planning must be based upon a sound understanding of the dispersion process. This is required to determine both the lateral s...

Oil spillage sites primarily contain various types of hydrocarbons, such as linear chain, polycyclic, and aromatic compounds, posing several detrimental effects on plants. Results from our previous study showed an alteration of various metabolomic parameters, indirectly resulting in an observable decline of growth in the mung seedlings upon incubation with phenol, toluene, xylene, and hexane. T...

nanotechnology has the potential to introduce revolutionary changes to several areas of oil and gasindustry such as exploration, production, enhanced oil recovery, and refining. in this paper, the effectof different concentrations of fe2o3 nanoparticles as a catalyst on the heavy oil viscosity at varioustemperatures is studied. furthermore, the effect of a mixture of fe2o3 nanoparticles and ste...
