Stakeholders of petroleum hydrocarbon-contaminated (PHC) sites aim to meet remediation goals cost-effectively. But contaminated are typically complex, and when inefficient strategies implemented, time money wasted. Various can be implemented for site almost all at some point involve a biological component. Therefore, during characterization, seeing the complete picture by obtaining multiple lin...

Thermal desorption (TD) is one of the methods commonly used to remediate contaminated soil. However, as water liquid adsorbent off-gas treatment system in TD stage, wastewater generated after multiple cycles stage has low biodegradability and contains complex organic pollutants. In addition petroleum hydrocarbon, there are also a lot ammonia, emulsified oil, phenols, aldehydes, ketones. this st...

lurestan province is petroliferous area. the reserved oil are in ilam and sarvak  (cretaceous ) and kangan ( lower triassic ) and dalan (permian) formations. the lurestan area had high exploration activity but contribution of source rocks in hydrocarbon accumulations isn’t clear. in this paper essential elements and process of hydrocarbon accumulation are introduced. candidate  source  rocks ar...

A lot of work has shown that despite the effectiveness traditional electrokinetic remediation (EKR) technology in decontaminating soils with different types and amounts contaminants, it can be enhanced by a number strategies for extra effective performance. This presents effect ethanol acetone cosolvents enhancing EKR crude oil contaminated soil (COCS), collected at depth 1 m from petroleum pip...

Diesel acts as a main energy source to complement human activities in Antarctica. However, the increased expedition Antarctica has threatened environment well its living organisms. While more efforts on use of renewable are being done, most still depend heavily diesel. contaminants their natural state known be persistent, complex and toxic. The low temperature worsens these issues, making pollu...

The increasing population density and industrialization are adversely affecting the environment globally. contamination of soil, agricultural lands, water bodies with petroleum wastes other hydrocarbon pollutants has become a serious environmental concern as perceived by impacts on aquatic marine ecosystem. Various investigations have provided novel insights into significant roles microbial act...

Total Petroleum Hydrocarbon ( TPH ) are environmental contaminants that are released into the marine environment through oil spills, industrial and domestic activities. TPH are readily transformed into more hydrophilic metabolites, which are accumulated in bile. Thus fish bile can be used as a biomarker of exposure of fish to TPH in the marine environment. in this study several stations were se...

Flourene and phenanthrene are organic compounds with high hydrophobicity and toxicity. Being recalcitrant in nature they are accumulating in the environment at an alarming concentration, posing serious threat to living beings. Thus in the present study, microorganisms were screened for their ability to degrade these contaminants at high concentrations in least period of time. Two out of fifteen...
