  • Land Contamination

    Land Contamination Identified: Contaminated land is a constant battle for developers looking to build houses / industrial sites or purpose built facilities. Contamination simply means an unacceptable risk to human health or the environment and therefore remediation or site clean up is required. Identifying contamination requires assessment, measurement and remediation. The primary contaminants ...

  • Toxic emissions, they’re in the water

    After decades of hammering on corporations to reduce their toxic air emissions, the Environmental Protection Agency (EPA) is now focusing on another source of nasty pollution, corporate water emissions. Although the Clean Water Act has technically been in place for well over three decades, the EPA has been lax in enforcing regulations, often due to thinly-stretched resources.Coal-fired power ...


  • Chemical emissions and the challenges ahead

    Thursday 3 May 2012 11:20 AM Dr Caroline Widdowson of Markes International examines the issue of chemicals in food packaging A comment piece published in Packaging News The occasional, but very widespread and damaging, bursts of media attention focusing on the range of chemicals found in food packaging, plastic bottles, wrappings and containers has meant that ‘materials emissions’ has ...

  • New insight on the spread of contamination from Fukushima

    A study on the transport of radioactive isotopes from Fukushima in the two months after the nuclear incident suggests that they were at official levels of contamination for 34,000 km2 of Japan, and that 2.8% of iodine radionuclides from the event were calculated to have reached the EU. The 2011 nuclear accident at Fukushima, Japan, caused the release of large amounts of radionuclides ...

  • ASTM D6728 - 11 standard test method for determination of contaminants in gas turbine and diesel engine fuel by rotating disc electrode atomic emission spectrometry

    Operating experience of gas turbines and diesel engines has shown that some of the ash-forming substances present in a fuel can lead to high temperature corrosion, ash deposition, and fuel system fouling. Ash-forming materials may be in a fuel as oil-soluble metallo-organic compounds as water-soluble salts or as solid foreign ...

  • Study reveals mercury contamination in Fish Nationwide

    Scientists detected mercury contamination in every fish sampled in 291 streams across the country, according to a U.S. Geological Survey study released today. About a quarter of these fish were found to contain mercury at levels exceeding the criterion for the protection of people who consume average amounts of fish, established by the U.S. Environmental ...

  • Gas analyzer builds complete picture of contamination

    Occupational health specialists from Wisconsin, USA, are utilising FTIR gas analysis technology to identify and quantify both known and unknown gas species in a wide variety of applications in which workers are potentially at risk. The FTIR instrument, a Gasmet DX4040, is owned by North Shore Environmental Construction (NSEC), a specialist in the management of hazardous materials response and ...

  • Shale gas extraction linked to water contamination

    A new study suggests shale gas extraction leads to methane contamination of underground water sources and calls for thorough surveys of methane levels at extraction sites. The study presents a timely insight into a relatively under-researched area of science that will help support decisions on the future of shale gas exploration. Shale gas, or natural gas extracted from sedimentary rocks ...

  • Site Remediation - Emissions Boundary Monitoring

    The remediation of contaminated land sites can prove to be a challenging undertaking.  There is considerable risk of chemical exposure to both the onsite workforce and to surrounding communities. To offsite receptors, the remediation process itself can become a significant route of exposure, with the excavation and uncovering of otherwise trapped contaminants resulting in potential ...

  • A new OSHwiki article highlights the risks and hazards of process-generated contaminants

    Process-generated contaminants can be generated as emissions from combustion processes, abrasion and/or other processes that physically or chemically degrade or otherwise modify the starting material(s), e.g. degradation/composting of organic materials. Such emissions are generally complex and variable mixtures of substances that are generated by processes or activities and are incidentally ...

  • 400,000tpa LDPE plant minimises VOC contamination in process gases - AirProtekt

    One of the world’s largest single stream LDPE production plants is to use a Regenerative Thermal Oxidation system (RTO) supplied by AirProtekt, the Cambridge based air pollution specialist, to remove VOCs in the process gases from the plant’s dryer system and six storage silos. AirProtekt is providing a complete VOC emission control solution for SABIC UK Petrochemicals’ 400,000tpa LDPE plant at ...

  • EPA study reveals widespread contamination of fish in U.S. lakes and reservoirs

    A new EPA study shows concentrations of toxic chemicals in fish tissue from lakes and reservoirs in nearly all 50 U.S. states. For the first time, EPA is able to estimate the percentage of lakes and reservoirs nationwide that have fish containing potentially harmful levels of chemicals such as mercury and PCBs. “These results reinforce Administrator Jackson’s strong call for revitalized ...

  • AirProtekt helps textile processor achieve Flourine contamination compliance

    A major UK major manufacturing has selected AirProtekt, the Cambridge based air pollution specialist, to remove Fluorine contaminants from its textile processing facility. AirProtekt was able to offer the textile company a complete solution by supplying a Regenerative Thermal Oxidation system (RTO) and a special scrubber system to remove Fluorine contaminants from the process exhaust ...

  • EPA, NREL partner to develop renewable energy on potentially contaminated sites

    The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) are evaluating the feasibility of developing renewable energy production on Superfund, brownfields, and former landfill or mining sites. Superfund sites are the most complex, uncontrolled or abandoned hazardous waste sites identified by EPA for cleanup due to the risk ...

  • Coal-Tar-Sealant a Major Source of PAH Contamination in Milwaukee Streams

    Runoff from pavement with coal-tar-based sealant is the primary source of toxic polycyclic aromatic hydrocarbons, or PAHs, to streambed sediments in Milwaukee, Wisconsin, according to a U.S. Geological Survey and Milwaukee Metropolitan Sewerage District ...

  • UN sets up green technology complex in contaminated ship yard site

    Hunters Point Shipyard on California's San Francisco Bay has gone through several rebirths in its more than 100 years of existence. Established as a commercial shipyard in 1870, it was appropriated by the US Navy at the beginning of World War II and became one of the Navy's major shipyards. After the war, it was home to the Naval Radiological Defense Laboratory, the US military's largest ...
