This paper introduces a practical teleoperated manipulator under nuclear radioactive environments. The system, called RoboSource herein, is designed to perform the leak detection of sealed gamma and neutron radioactive sources used for oil well…

A practical automatic system called ALDS (automatic leak detection system) is presented in this paper, which is implemented for leak detection of sealed radioactive sources used for oil well logging in oilfields. This ALDS is able to accomplish the…

This work assesses the applicability of reflectance spectroscopy to monitor petroleum hydrocarbon (PHC) leaks in petroleum facilities using the direct detection of the pollutant in bare soils. A controlled, lab-scale experiment is conducted, where…

Accidental releases of hazardous waste related to the extraction, refining, and transport of oil and gas are inevitable. Petroleum facilities and intrinsic pipelines present environmental pollution risks, threatening both human health and ecosystems.…

Oil pollution does great harm to ecological environment and human health. The oil contamination in the soil mainly comes from the leakage in the process of exploitation, refining, transportation and the storage of oil. Now, global situation of soil…

The subsurface contamination by petroleum hydrocarbons (PHC) from leaking underground storage tanks, pipelines and refilling stations is one of the serious issues directly affecting the quality of groundwater. Application of advanced oxidation…

Based on the hydrogeological survey and groundwater environmental investigation at an abandoned oil refinement factory, a site-specific groundwater flow and solute transport model was constructed to support the development of groundwater remediation…

Clay minerals present within the groundwater aquifers is found to influence the migration of hazardous solutes like radionuclides and petroleum hydrocarbons. The presence of clay minerals within the aquifers is observed to either enhance or retard…

Petroleum contamination of environmental matrices is a pervasive, global problem. Crude oil exploration, processing, handling and transport release significant amounts of petroleum hydrocarbons into the environment. Many petroleum compounds are known…

Petroleum hydrocarbons (PHC) enter the environment due to exploration, transportation, usage and spills. PHC contamination is of major concern worldwide due to the damage they cause to the environment. Clean up of hydrocarbon-contaminated sites is…

Conventional contaminated site assessment requires sophisticated sampling and laboratory analyses, which are costly and time consuming. There is a trend for soil analyses to shift from complex laboratory procedures to rapid, simple and…

We used a reactive transport model to investigate the cycling of geogenic arsenic (As) in a petroleum-contaminated aquifer. We simulated As mobilization and sequestration using surface complexation reactions with Fe(OH)3 during petroleum…

This study investigated the pyrolysis of polystyrene (PS) packaging waste for transportation fuel application of the oil product, with a specific focus on the effect of contamination and the scale-up of the process. The oil yield and calorific value…

Due to the extended oil extraction and transportation in Russia and other oil-producing countries, many lands remain contaminated because of accidental spills. This situation requires the cost-effective and efficient remediation of…

The remediation of organic pollutant-heavy metal co-contaminated soil is a great challenge. Immobilized microorganism technology (IMT) is a potential approach to remediate co-contaminated soil. In this study, we evaluated the feasibility of IMT for…

A sub-scale and an engineering-scale burner were designed, built, and tested in an effort to develop a single-nozzle burner capable of efficiently atomizing and burning neat, emulsified, and weathered crude oil for spill response and remediation. The…

We developed a novel methodology that combines thermo-analytical measurements and mathematical methods to inform the reliable pyrolytic treatment of specific soil/contaminant systems. Our approach improves upon current "black-box" design methods that…

A bacterial consortium, constructed from the oil contaminated soil, mainly consisting of Pseudomonas sp., together with fertilizing, rice husk application, and plowing, was used for the field in situ bioremediation of oil contaminated site in…

During the 1991 Gulf War, oil wells in the oil fields of Kuwait were set aflame and destroyed. This resulted in severe crude oil pollution of the countries only fresh water aquifers. Here, for the first time the natural attenuation and biodegradation…

Crude oil contamination greatly influence soil bacterial community. Proliferative microbes in the crude oil-contaminated soil are closely related to the living conditions. Oil wells in the Yellow River Delta Natural Reserve (YRDNR) region is an ideal…

The increasing exploitation of the unconventional bitumen-derived oils from Alberta (Canada) have raised new environmental concerns because they are inherently different than conventional oils. Previous studies mainly focused on diluted bitumen, but…

Biogeochemical gradient forms in vadose zone, yet little is known about the assembly processes of microbial communities in this zone under petroleum disturbance. This study collected vadose zone soils at three sites with 0, 5, and 30 years of…

Singapore is a highly industrialised country with an important oil industry resulting in a significant environmental impact, creating vast amounts of hydrocarbon waste that needs to be remediated. Here we report on the commercial scale bioremediation…

The role of natural attenuation processes in groundwater contamination by petroleum hydrocarbons is of intense scientific and practical interest. This study provides insight into the biodegradation effects in groundwater at a site contaminated by…

Mycoremediation, an aspect of bioremediation, has been investigated for some decades. However, there seems to be little progress on its commercial application to petroleum-contaminated soils despite some promising outcomes. In this review,…

In order to reduce the cost of phytoremediators selection in phytoremediation on petroleum-contaminated soils, long-term experiments and in-situ trials included, an evaluation system for plant selection in phytroremediaiton was conducted in…

Accidental oil leaks and spills can often result in severe soil and groundwater pollution. In situ chemical oxidation (ISCO) is a powerful and efficient remediation technology. In this review, the applications and recent advances of three commonly…

Deterioration of our terrestrial environment due to decreasing soil quality brought on by crude oil spills and leakages is a major issue. In this study, soil samples were prepared by mixing clay (bentonite) and sand contaminated with 5 and 10 wt%…

The oil and gas industry spends significant time and money assessing crude oil impacts in soil. Current industry practice involves sending soil samples to an off-site laboratory for the analysis of total petroleum hydrocarbons (TPH) with standard…

Rhizoremediation is increasingly becoming a green and sustainable alternative to physico-chemical methods for remediation of contaminated environments through the utilization of symbiotic relationship between plants and their associated soil…

The indigenous hydrocarbons in samples of zooplankton, shrimp (Penaeus aztecus) and sediment are extracted by refluxing with a series of organic solvents fractionated by column chromatography and then resolved by high resolution gas chromatography.…

This study assessed the phytoextraction of heavy metals and crude oil contaminants from the soil using native grass Cynodon dactylon under laboratory conditions. A comparative assessment of biomass of grass and the total petroleum hydrocarbons in…

In every oil-rich and oil-exploiting country, there is unprecedented environmental pollution, soil inclusive. As a result, colossal sums of money are spent on maintaining soil health. The concern for remediation arises from structural complexity and…
