  • Chronic effects of non‐weathered and weathered crude oil and dispersant associated with the deepwater horizon incident on development of larvae of the eastern oyster, Crassostrea virginica

    In this study we examined the effects of chronic exposure of eastern oyster (Crassostrea virginica) larvae to the water‐accommodated fractions of fresh and weathered oils collected from the Deepwater Horizon (DWH) incident, with and without additions of the dispersant Corexit 9500A, as well as to solutions of Corexit alone. We found that both shell growth of larvae exposed to test materials ...

  • Acute effects of non‐weathered and weathered crude oil and dispersant associated with the deepwater horizon incident on the development of marine bivalve and echinoderm larvae

    Acute toxicity tests (48 to 96 hours duration) were conducted with larvae of two echinoderm species (Strongylocentrotus purpuratus and Dendraster excentricus) and four bivalve mollusk species (Crassostrea virginica, Crassostrea gigas, Mytilus galloprovincialis, and Mercenaria mercenaria). Developing larvae were exposed to water‐accommodated fractions (WAFs) and chemically enhanced water ...

  • Anglo platinum and ultraspin clean up

    At Waterval mine, 69% of environmental incidents are related to the spillage of fuel, oil, grease and lubricants. Most of these hydrocarbon spillages can be attributed to TM3 equipment used at the mine. As part of a long-term management plan to address these hydrocarbon spillage incidents, Anglo Platinum has installed Ultraspin technology at Waterval mine. This technology has two main ...

  • Proof That Bacteria Degrade Oil

    There has been a lot of publicity and ‘noise’ around the ability of bacteria to degrade oil, especially following BP’s Gulf of Mexico incident.  However little has been shown to prove that biological remediation is an effective means of treating oil contamination. Over many years CBIO have worked to develop a range of a microbial products that have proven to be able to ...

  • Petrol and heating oil bioremediation using EU70 (case study)

    As a result of an accident a tanker lost its load of petrol and heating fuel. A large quantity of fuel approximately 2000 litres soaked into the soil. Analyses revealed that the average level of hydrocarbons present was in the order of 0.55 %. The pollution affected an area of 100 m2 and to a depth of 0.6 m. Our goal was to reduce hydrocarbon levels to the lowest possible value in order to ...

  • Desorption kinetics of naphthalene from sediment particles: batch and stepwise desorption approach

    We investigated three major parameters in simulating desorption behaviours: the pre-contamination period, dilution by clean water mass (dilution ratio) and the length of the time interval between dilutions, in both batch and stepwise desorption experiments using particles pre-contaminated with a polycyclic aromatic hydrocarbon, naphthalene (NAPH). We found that the dilution ratio plays a major ...

  • 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 ...

  • Impacts of Deepwater Horizon crude oil exposure on adult mahi‐mahi (Coryphaena hippurus) swim performance

    The temporal and geographic attributes of the Deepwater Horizon incident in 2010 likely exposed pelagic game fish species, such as mahi‐mahi, to crude oil. Although much of the research assessing the effects of the spill has focused on early life stages of fish, studies examining whole‐animal physiological responses of adult marine fish species are lacking. Using swim chamber respirometry, the ...

  • Detection and measurement of toxic gases from destructive testing of batteries

    Problem Statement New formulations of organic-compound-based batteries for vehicle use must be tested for release of potentially harmful and toxic gases if crushed in accidents. Potential gases include hydrocarbons, fluorocarbons, and hydrogen fluoride, released within seconds of an incident. Actual time-resolved and quantitative data are required from destructive testing to ascertain ...

  • BTs, PAHs, OCPs and PCBs in sediments and bivalve mollusks in a mid‐latitude environment from the Patagonian coastal zone

    BTs, PAHs, OCPs and PCBs were assessed in a mid‐latitude environment of the Patagonian coast, distant from important pollutant sources. Bioaccumulation processes through bottom sediment re‐suspension were suggested by BTs level found in surface sediment ( ...

  • Advancing Green Technology case study

    Challenge: A subject of considerable research in recent years, sulfate reducing bacteria have been demonstrated to be a dominant factor in the natural anaerobic biodegradation of petroleum hydrocarbons dissolved in groundwater. Antea Group has conducted extensive pilot testing at hundreds of sites across the United States that demonstrate the benefits of enhancing ...

  • Offshore oil spill clean up case study

    In the event of a major incident occurring offshore, for example a tanker casualty running aground or breaking up for any reason, it is of paramount importance to deploy emergency response to protect and save human life. Once this has been done an assessment of the casualty should be made on whether it is possible to salvage the vessel and its contents and to assess the type and amount of oil ...

  • Revealing the costs of air pollution from industrial facilities in Europe

    This European Environment Agency (EEA) report assesses the damage costs to health and the environment resulting from pollutants emitted from industrial facilities. It is based on the latest information, namely for 2009, publicly available through the European Pollutant Release and Transfer Register (E-PRTR, 2011) in line with the United Nations Economic Commission for Europe (UNECE) Aarhus ...

  • Ecological Conditioning and Optimisation of a Once-Through Cooling Water System

    For the coming decade, Dow Benelux will need antifouling treatment for its cooling water system. Hypochlorite dosing is still considered to be the best available technology (BAT). This is based on proven effectiveness, large experience, moderate costs, opportunities to further optimise the chlorination procedure, and by the fact that in earlier studies low-level ...

  • Building on a legacy of PID development

    Summary From the 1970s to the present day, photo-ionisation detectors (PIDs) have been at the front line of efforts to detect volatile organic compounds. As industrial hygiene has become ever more important and exposure limits for VOCs have reduced, PID technology has continued to develop, providing reliable detection under challenging environmental conditions at concentrations right down to ...

  • From Pilot Studies to Full Scale Plant

    Natural gas is widely used as a primary energy source and is one of the most efficient fuel source. For this reason, more and more gas is utilized exceeding existent production facilities. Oil and gas companies therefore expand there measures and step behind borders finding and exploit new resources. One area of major interest is the Barents Sea, a remote area far from industry and civilisation. ...

  • Bioremediation of an Oil Spill

    Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly ...


  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...
