Geotechnical properties of hydrocarbon-contaminated soils: a comprehensive review

Low Temperature Ex Situ Bioremediation of Hydrocarbon Contaminated Soils

Many oil degrading bacteria thrive within the mesophilic temperature range, between 20°C and 40°C; bioremediation practitioners view this as the optimal temperature range for microbially driven hydrocarbon remediation. Environmental managers generally halt active bioremediation projects during the winter months as microbial activity is thought to be insignificant and not cost effective. Recent ...

Phytoremediation of hydrocarbon-contaminated soils: principles and applications

Persulfate Oxidation for the Remediation of Petroleum Hydrocarbon-Contaminated Soils

The feasibility of total petroleum hydrocarbon-contaminated (TPH) soil remediation was studied using persulfate oxidation. Factors tested included type of activator, persulfate concentration, number of persulfate applications, and reaction time. Probe chemicals were used to study effi ciency of the persulfate oxidation mechanism. The best activation method used Fe2+, which achieved 40.8% TPH de...

Bioremediation treatment of hydrocarbon-contaminated Arctic soils: influencing parameters.

The Arctic environment is very vulnerable and sensitive to hydrocarbon pollutants. Soil bioremediation is attracting interest as a promising and cost-effective clean-up and soil decontamination technology in the Arctic regions. However, remoteness, lack of appropriate infrastructure, the harsh climatic conditions in the Arctic and some physical and chemical properties of Arctic soils may reduce...

Investigation of Hydrocarbon-degrading Microbial Communities of Petroleum Hydrocarbon Contaminated Soils in Harghita County, Romania

Microorganisms able to degrade hydrocarbon pollutants (gasoline, and other petroleum derivatives) have been isolated from two contaminated areas (Sândominic and Bălan) by enrichment technique. The hydrocarbon degradative capacity of contaminated sites were determined using “Biometer flasks” (respiratory CO2 production measurement). Total counts and hydrocarbon degrading counts were determined u...
