  • Effect of iodine chemical form on thyroid doses during a severe accident

    In most of the accidents that may occur in nuclear reactors, the short-term radiological consequences are expected to be dominated by isotopes of iodine. The assessment of doses resulting from iodine release during a severe reactor accident requires knowledge of the iodine chemical forms and removal mechanisms prior to the release to the environment. In this paper, the arguments concerning iodine ...

  • The Chemical Aspect of NOx Scrubbing

    With the passage of the 1990 Clean Air Act Amendments, many chemical and metal industries and utility producers will now be required to further limit the amount of NOx (Nitrogen Oxides) produced. NOx is a precursor to ozone in the atmosphere, and is believed to be a major contributor to acidic deposition (acid rain). Formation of ozone: NOx is produced in a variety of ...

  • Counting the costs of chemical incidents

    The consequences of a lack of control when using chemical substances in the workplace are well known and apparent.  Any health and safety expert can tell you of at least one major accident whereby poor chemical management policies and procedures have lead to disaster.  Examples include Bhopal, Grangemouth, Flixborough, Seveso and more recently, Buncefield.  Major accidents like ...

  • How To Handle Chemical Spills & Cleanups

    FAST-ACT is designed for liquid and vapor chemical releases, but the chemicals it attacks does not need to be limited to what we traditionally think of as a chemical spill. Toxic and noxious chemicals can come from a variety of sources such as waste water, decomposition, household chemicals, and animals. Since FAST-ACT can be applied to liquid spill or vapor release enabling Emergency Responders ...

  • Hazardous chemicals and proper storage solutions

    Many acceptable categorical storage schemes have been proposed and used by laboratories in academic, industrial, government and medical institutions. The common features uniting all these plans is the separation of incompatible materials. The differences in these various storage schemes arises in the number of groups that should be established for segregation purposes. The ten most commonly cited ...

  • 6 Surprising sources of chemical exposure

    6 Surprising sources of chemical exposureWe may be careful with that bottle of bleach, can of paint or the ominous bottle of unknown chemical solution found in the basement. But what about everyday actions that may expose us unknowingly to potentially harmful substances? Read on to find some surprising sources of chemical exposure, and what to do about them. 1 - Shower The ...

  • 2011 Predictions for U.S. Chemicals Management

    The trends established by the Obama administration will continue despite the Congressional midterm elections in November, says Lynn L. Bergeson. The elections’ impact, notably the new Republican majority in the House and the razor thin Democratic majority in the Senate, will nonetheless have an important, but uncertain impact on the US Environmental Protection Agency. Early indications are ...

  • Chemical contaminants as a factor of soil-subsurface metagenesis*

    The soil and the subsurface region below it are two interrelated natural bodies that comprise the earth’s upper layer from land surface to aquifers. The ratio between these phases fluctuates as a function of environmental conditions, while the subsurface water content ranges from air-dried to completely watersaturated. Because the soil-subsurface water content is controlled by ...

  • Phosphate release from waste stabilisation pond sludge: significance and fate of polyphosphate

    Net phosphorus removal from waste stabilisation pond (WSP) systems is governed by the rate of phosphorus incorporation into the sludge layer and the rate of phosphorus release from this sludge back to the overlying wastewater. Luxury uptake of phosphorus by microalgae has been shown to occur under WSP conditions in the laboratory; however, the significance of this mechanism and the fate of ...

  • Composting releases less air pollution than previously thought - study

    A new study funded by the California Integrated Waste Board (CIWMB) indicates that well-managed composting of green waste and food waste releases significantly less air pollution than previously thought. The study also demonstrates that a relatively inexpensive management technique - covering active compost piles with a layer of finished compost - may lower air emissions even further, by as ...

  • In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

    A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...

  • A Chemical Dynamics Model for CAH Remediation with Polylactate Esters.

    ABSTRACT: The polylactate esters of sorbitol, xylitol and glycerol are a class of new chemical compounds that slowly release lactic acid into groundwater. The lactic acid is biotransformed into pyruvic acid and subsequently into acetic acid releasing hydrogen in both steps. The hydrogen is used by naturally occurring dechlorinating bacteria to reduce PCE to ethene by way of TCE, DCE and VC. A ...

  • Manmade chemicals a major cause of global climate change

    Although the Earth?s climate evolves naturally over time, the major cause of climate change that is harmful and lead to unfavorable weather, water patterns, growth patterns are due to the release of manmade chemicals. While these chemicals are necessary to produce certain items, operate essential refrigeration equipment, or make our daily lives easier, they are a danger to the environment and the ...

  • Partitioning and availability of sediment-bound metals following final sewage effluent release to a lowland river

    A simple partitioning scheme was used to assess the partitioning and behaviour of copper, cadmium, iron, lead and manganese within the surface waters and sediments of the River Yare, Norfolk, UK, following the discharge of final effluent to the water course from municipal sewage treatment works (STW). Sewage effluent discharges were shown to increase metal concentrations and complexation ...

  • EPA takes unprecedented action on `Risk List` chemicals

    The U.S. Environmental Protection Agency (EPA) on Dec. 30, 2009, issued a breathtaking series of action plans on 'Risk List' chemicals that will shape future legislative proposals which industry will need to participate in and monitor. EPA has never announced so many actions under the Toxic Substances Control Act (TSCA), nor has it ever so widely cited use of Section 6. That they were issued in ...

  • Site Vulnerability Assessments for Facilities That Use, Store, or Transport Chemicals

    In response to pressing issues facing the new Department of Homeland Security, over 15,000 chemical and industrial plants may have to evaluate their vulnerability to terrorist attack and improve countermeasures at their facilities. Federal lawmakers are considering two bills requiring facilities to submit site security plans: the Chemical Security Act (Senate Bill S. 157, reintroduced in January, ...

  • Huge Windfalls for Chemical Firms under Emissions Trading Scheme

    Emissions data for 2002 have confirmed that the UK emissions trading scheme has been undermined by huge quantities of 'hot air' from three chemical companies. The figures challenge the Government's continuing claims for the scheme's environmental benefits. The UK's pioneering greenhouse gas emissions trading scheme was launched a year ago. Following an auction, 34 organisations took on emission ...
