The remediation of oil contaminated soils has been a major problem in oil producing countries and recently use of plants to clean such soils has been on investigation. In order to identify plants that can enhance the remediation of crude oil contaminated soil, the effect of the growth of G. max on the physico-chemistry and crude oil content of soil contaminated with different concentrations of ...

Remediation of the petroleum contaminated soil is essential to maintain the sustainable development of soil ecosystem. Bioremediation using microorganisms and plants is a promising method for the degradation of crude oil contaminants. The effects of different remediation treatments, including nitrogen addition, Suaeda salsa planting, and arbuscular mycorrhiza (AM) fungi inoculation individually...

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% ...

a study was conducted in 2010 to investigate the effects of crude oil contaminated soil on biomass accumulation injatropha curcas seedlings in asaba, delta state, nigeria. oil levels used were 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0% w/w. the trial was arranged in a randomized complete block design with four replications and monitored for 12 weeks after transplanting. results showed that contamination...

The efficiency of Bacillus subtilis DM-04 and Pseudomonas aeruginosa M and NM strains isolated from a petroleum contaminated soil sample from North-East India was compared for the biodegradation of crude petroleum-oil hydrocarbons in soil and shake flask study. These bacterial strains could utilize crude petroleum-oil hydrocarbons as sole source of carbon and energy. Bioaugmentation of TPH cont...

The effect of crude oil contaminated soil on the growth of seashore Paspalum ( Paspalum vaginatum .) seedlings was investigated. Plants were grown in soil containing different concentrations: 0%, 0.5%, 1.0%, 2.0% and 3% (w/w) of Abura crude petroleum oil. Growth parameter such as shoot number, shoot length, leaf area and biomass accumulation were evaluated. The results showed that crude oil imp...

toxicity and damages caused by soil pollution with crude oil and its microbial responses may depend on nitrogen bioavailability and its form. so, the main objective of this study is to investigate the effects of crude oil and various forms of n consumption on c mineralization and microbial biomass. the experiment was done in the form of factorial (3×4) design using crd (completely randomized de...

Thermal remediation of the soil contaminated with crude oil using microwave heating enhanced by carbon fiber (CF) was explored. The contaminated soil was treated with 2.45 GHz microwave, and CF was added to improve the conversion of microwave energy into thermal energy to heat the soil. During microwave heating, the oil contaminant was removed from the soil matrix and recovered by a condensatio...

The study has been carried out with two broad objectives – to observe the effect of crude oil contamination on consolidation properties of soil and to predict the change in the properties in the form of mathematical correlation. The properties studied here are co efficient of compression (Cv) and compression index (Cc). Four types of naturally available soil (CH, CL, CI and SC) collected from d...

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...
