The present study investigated the coupling effect of biodegradation and media filtration in treating hydrocarbon contaminated water. The study recorded reductions in total petroleum hydrocarbon, total dissolved solids, turbidity and microbial load. The study was essentially a simulated pump and treat process that involved the pumping of hydrocarbon contaminated water for treatment in a locally...

Hydrocarbon systems have been intensively studied via numerical methods, including electronic structure computations, molecular dynamics and Monte Carlo simulations. Typically, these methods require an initial structural model (atomic positions and types, topology, etc.) that may be produced using scripts and/or modeling tools. For many systems, however, these building methods may be ineffectiv...

Controlled laboratory microcosms were used to research the phytoremediation potential of lupines (Lupinus chamissonis) for hydrocarbon-contaminated groundwater at a former oil field near Guadalupe, California. During oil production in the Guadalupe Oil Field, a kerosene-like hydrocarbon mixture was used as a diluent to improve the flow of the heavy crude oil. Leaking tanks and pipes resulted in...

The paper of Ranchou-Peyruse et al. (2016) presents evidence of hydrocarbon degraders present in formation water from a depth of 853 m in the Paris Basin in France. Such deep formation waters are used for storing natural gas. This is a challenging environment for sampling, considering that at the designated depths, the acquisition of sediments is difficult and often beyond the funding of most r...

During the Deepwater Horizon oil well blowout in the Gulf of Mexico, the application of 7 million liters of chemical dispersants aimed to stimulate microbial crude oil degradation by increasing the bioavailability of oil compounds. However, the effects of dispersants on oil biodegradation rates are debated. In laboratory experiments, we simulated environmental conditions comparable to the hydro...

Corrosion processes in two North Sea oil production pipelines were studied by analyzing pig envelope samples via metagenomic and metabolomic techniques. Both production systems have similar physico-chemical properties and injection waters are treated with nitrate, but one pipeline experiences severe corrosion and the other does not. Early and late pigging material was collected to gain insight ...

Studies of workers exposed to hydrocarbon solvents are reviewed in order to address the question, 'Does long-term human exposure to hydrocarbon solvents at concentrations around occupational exposure limits result in clinically important neurobehavioural effects?' Studies selected evaluated exposure-response (E-R) trends with some control of potential confounders. Tests of neurobehavioural perf...
