  • Solution blooming for fracking spills?

    Blooming salts may clean up after brine spills North Dakota's oil boom can have a salty side-effect. Wastewater from oil drilling and hydraulic fracturing – or fracking – is often laden with salts and can spill, contaminating soils. In 2014, for example, 42 such brine spills per week, on average, were recorded in North Dakota. Brine spills introduce so ...

  • Fabrication of polysiloxane-modified polyurethane sponge as low-cost organics/water separation and selective absorption material

    Through sol-gel and dip-coating processes, commercial polyurethane sponge modified by polysiloxane was fabricated under low temperature (60 °C) and atmosphere. The contact angle of the obtained polysiloxane/polyurethane sponge is 145 ± 5°. Hence, the polysiloxane/polyurethane sponge could float on water and selectively absorb organics from the surface of the water, indicating simultaneous ...

  • Case study - Nigeria crude oil in soil site

    Safic Technologies, Ltd. - Port Harcourt A pilot study was conducted testing soil samples collected from a pipeline spill. Split samples were sent to Sitelab for EDRO analysis and results were the same. Samples were also sent to a Nigerian lab and a highly reputable lab in the United States for confirmation. After testing the samples a second time, the American lab got better results. ...

  • Biosurfactant produced by a Rhodococcus erythropolis mutant as an oil spill response agent

    Biosurfactants have been considered as superior alternatives to currently used surfactants as they are generally more biodegradable, less toxic, and better at enhancing biodegradation. However, the application of biosurfactants is limited by the availability of economic biosurfactants and the corresponding producers that can work effectively. Hyperproducers generated by metabolic engineering ...

  • Effects of chemical dispersant and seasonal conditions on the fate of spilled oil – modelling of a hypothetical spill near Saint John, NB

    The proposed Energy East pipeline project has raised concerns about potential oil spills in Saint John, New Brunswick. While environmental conditions could pose challenges for using mechanical recovery methods if a spill occurs, chemical dispersant could be an alternative. However, the application of chemical dispersant in shallow water and costal zones remains an issue of debate. Furthermore, ...

  • Enhancing the hydrophobicity of mangrove bark by esterification for oil adsorption

    Oil spills generally cause worldwide concern due to their detrimental effects on the environment and the economy. An assortment of commercial systems has been developed to control these spills, including the use of agricultural wastes as sorbents. This work deals with raw and modified mangrove barks (Rhizophora apiculata), an industrial lignocellulosic waste, as a low cost adsorbent for ...

  • New oil spill response application note from China

    The Problem: Oil may spill out in the process of oil exploration & development, refining, storage and transportation and enter into open water environment like oceanic environment due to incident or incorrect operation. Oil spill damages include to human heath, safety, ecological environment, aquaculture. In China, the State Oceanic Administration requires the oil content in the discharge to ...

  • Study of the dispersion/settling of oil–mineral–aggregates using particle tracking model and assessment of their potential risks

    A random walk particle tracking model was used to simulate the motions of oil–mineral–aggregates (OMAs) under hydrodynamic conditions involving wave–induced velocities, random velocities due to turbulence, and the settling velocity due to gravity. Wave–induced and settling velocities for OMAs determined from the application of Stokes's theory and empirical equations derived from experimental data ...

  • Position Brief on oil and gas development of the Arctic

    Background The Arctic Circle encompasses roughly 6% of the earth’s surface. Wetlands make up about 60% of the total Arctic land mass and are the predominant ecosystem, however they are not well defined or understood. Arctic wetlands provide a wide range of ecosystem services such as the maintenance of permafrost, hydrology and water quality. Arctic wetlands have the highest ...

  • Practical quantification method for Heinz bodies in birds applicable to rapid response field scenarios

    Oil‐induced oxidative injury to red blood cells results in Heinz body hemolytic anemia. Here, the authors evaluated three Heinz body staining techniques in brown pelican (Pelecanus occidentalis) blood. Using a range of in vitro acetylphenylhydrazine incubations, the authors validated a field‐adapted technique against laboratory wet‐mounts and verified the stability of this technique for one ...

  • Case study - Public-private partnership successfully tests leakwise early oil spill detection sensor in the tidal Delaware river

    Background In the summer of 2011, the Delaware River Basin Commission (DRBC) and the U.S. Geological Survey (USGS) collaborated with GE Analytical Instruments on a unique test deployment of an oil sheen sensor in the tidal Delaware River. The idea for the test deployment arose during meetings of the Delaware River and Bay Oil Spill Advisory Committee, which includes organizations and ...

  • Toxicity of crude oil chemically dispersed in a wave tank to embryos of Atlantic herring (Clupea harengus)

    Tests of crude oil toxicity to fish are often chronic, exposing embryos from fertilization to hatch to oil solutions prepared using standard mixing procedures. However, during oil spills, fish are not often exposed for long periods and the dynamic nature of the ocean is not easily replicated in the lab. Our objective was to determine if brief exposures of Atlantic herring (Clupea harengus) ...

  • Quantifying population‐level risks using an individual‐based model: Sea otters, Harlequin Ducks, and the Exxon Valdez oil spill

    Ecological risk assessments need to advance beyond evaluating risks to individuals that are largely based on toxicity studies conducted on a few species under laboratory conditions, to assessing population‐level risks to the environment, including considerations of variability and uncertainty. Two individual‐based models (IBMs), recently developed to assess current risks to sea otters and ...

  • Trans-boundary marine oil pollution and its international legal aspects

    Marine pollution control is a sensitive topic, which has gained importance recently due to crude oil spills which in turn has led to many recent international legal developments. This paper examines the effectiveness of international marine laws in imputing liability and calculating damages where more than one nation is affected. The main international agreements covering the international marine ...

For a given project, a suitable sampling plan – developed by ...


  • Analytical Testing for Corexit Dispersants Used in the Gulf Spill

    The analysis of various sample matrices (seawater, sediment, tissue) to determine concentrations of Corexit dispersants used in the Gulf spill requires the use of one or more of the components in the dispersant as a tracer. The primary active ingredient (i.e. the primary surfactant) in the Corexit products is Dioctyl Sulfosuccinate Sodium Salt (DOSS). The other primary ingredients function as ...


  • Bioremediation of fuel oil spill at a coastal naval air station in the united kingdom

    Introduction Approximately 1000 gallons of fuel oil had seeped from broken storage tank lines into the soil matrix beneath a boiler house. Oil was subsequently forced from beneath the boiler building by periodic heavy rainfall. The fuel oil migrated down a slope into a farmer"s field causing extensive damage to the vegetation and grazing area inhabited by sheep. ...
