In vitro studies have been carried out to establish the nutritional differences between crude and refined vegetable oils; however, the impact of the consumption of these foods on metabolism, in particular the effect of buriti oil, needs to be further evaluated. The aim of this study was to evaluate the biochemical and murine parameters and the vitamin A and E status in young rats fed with diets...

One of the most important anthropogenic pollution types in countries with oil production is soil and water contamination by petroleum. Phytoremediation is an emerging green technology for cleaning up polluted soil. A greenhouse experiment was conducted to study the effect of oil-contaminated soil on Echinacea purpurea with four concentrations of crude oil - contaminated soil: control = 0, 0.5% ...

This study was undertaken to investigate the effects of Bonny light crude oil (specific gravity = 0.81; API gravity 43.2 0 ) on the numerical composition of soil bacteria and fungi and relative distribution of Gram positive and Gram negative soil bacteria. Eight different levels of the crude oil (0.5, 1.0, 2.0, 2.5, 5.0, 10.0, 15.0 or 20.0% v/w of soil) were used for the controlled pollution of...

Investigations were made on the effect of Bonny light crude oil on stem sprouting of Talinum triangulare. Five concentrations of crude oil viz, 2.5mls, 5.0ml, 7.5ml, 10.0mls and 12ml were applied to 7kg of dry soil in perforated polyethene bags. The experiment was carried out on a completely randomized design (CRD) and replicated 6 times. Data on the number of days to sprouting, number of branc...

the degradation of crude oil under a no-control and dispersant-control setting was evaluated using loss of biological activity test, microbial population growth and measurements of optical transmittance of test media. comparison of the toxicity of crude oil under the no-control setting to crude oil-dispersant mixture revealed that the mixture was about 2 times more toxic than the crude oil unde...

The extensive fluctuations in oil prices have vast impacts on economies. The economical instability may be observed for both oil-exporting and oil-importing countries due to high volatility of oil prices. Oil price data as a time series is a highly nonlinear system which exhibits complex patterns. Traditional oil time series analysis employs statistical methods to model and explain the oil data...

With the rapidly increasing global energy needs, offshore oil production has become an attractive source of energy. Supplying offshore oil production installations is a complex logistics problem that hinges on many factors with significant uncertainties. So, it is critical to provide the necessary supplies and services without interruption. In a typical offshore oil production effort, oil compa...

The effect of bonny-light crude oil was assessed in adult albino rats. The rats were administered with 200, 400, and 800 mg/kg body weight of the crude oil orally for 7 days. Fluid intake was measured daily, initial and final animal body was recorded. The toxic effects on the kidneys were assessed and histological studies carried out. The results revealed that the kidney cells were damaged; cru...
