Petroleum Hydrocarbon Biodegradability in Soil – Implications for Bioremediation
The development of human civilization throughout history has led to growing disruption of the natural balance and the occurrence of different types of pollution. The world depends on oil, and the use of oil as fuel has led to intensive economic development worldwide. The great need for this energy source has led to the gradual exhaustion of natural oil reserves. However, mankind will witness th...
متن کاملEffect of Soil Washing on Petroleum- Hydrocarbon Distribution on Sand Surfaces
A soil washing study was performed to evaluate the treatability of New River sand contaminated in the laboratory with a petroleum distillate. Unaltered and base-extracted sands were mixed with petroleum hydrocarbons, equilibrated, and washed with water or a surfactant at two different pH values (7 and 12). The surfactant had no significant effect on contaminant removal efficiencies at neutral p...
متن کاملSoil Washing for Remediation of Non Volatile Hydrocarbon Polluted Soils
This paper illustrates the possibilities of applying what is essentially a physical soil-washing technique for treatment of soil contaminated by semi-volatile hydrocarbons in order to reduce the level of pollution to that permitted by Italian regulations. The ground around a factory producing lubricating-oil additives consists of silty-sandy soils, which have long been contaminated by heavy hyd...
متن کاملUsing poly-glutamic acid as soil-washing agent to remediate heavy metal-contaminated soils.
The extraction efficiency of heavy metals from soils using three forms of gamma poly-glutamic acid (γ-PGA) as the washing agents was investigated. Controlling factors including agent concentrations, extraction time, pH, and liquid to soil ratio were evaluated to determine the optimum operational conditions. The distribution of heavy metal species in soils before and after extraction processes w...
متن کاملSoil and brownfield bioremediation
Soil contamination with petroleum hydrocarbons, persistent organic pollutants, halogenated organic chemicals and toxic metal(loid)s is a serious global problem affecting the human and ecological health. Over the past half-century, the technological and industrial advancements have led to the creation of a large number of brownfields, most of these located in the centre of dense cities all over ...
