    Introduction   The chlorinated dibenzo-p-dioxins are a class of compounds that are loosely referred to as dioxins. There are 75 possible dioxins. The one with four chlorine atoms at positions 2, 3, 7 and 8 of the ...

  • Dioxines and furanes - Case Study

    Example: Scrap copper recycling, cobalt for battery production Similar tasks: Metal recycling, roast processes, thermal waste disposal When recycling metals - as in scrap copper recycling (mostly cable material) - toxic waste gases often occur. The raw materials to be recycled are injected in a shaft kiln that emits dust, organic contaminants, carbon monoxide, dioxins as well as furans. A ...

  • Dioxins and Furans on the Equity-5

    Dioxins and furans are byproducts of several different industrial processes, including incineration and paper bleaching. The extreme toxicity of several of these compounds has made their analysis in environmental samples increasingly important. In this application, the 60m x 0.25mm ID x 0.25µm Equity-5 was used to separate all 17 of the 2,3,7,8-substituted PCDDs and PCDFs listed in US EPA ...

  • Dioxin Exposure and Health in the European Union

    A study on the Evaluation of the occurrence of dioxins and POPs in wastes and their potential to enter the food chainwas financed by the Environment Directorate-General of the European Commission and coordinated by the Joint Research Centre, Environment Institute, Soil and Waste Unit and aimed at investigating to what extent the use of contaminated wastes in the production of animal feedstuffs ...


  • Carbon Injection Proves Effective In Removing Dioxins

    Untitled Document Summary: During the past several years, there has been growing concern about emission of polychlorinated di-benzo-p-dioxins and polychlorinated ...

  • Compilation of EU Dioxin Exposure and Health Data

    Introduction There is considerable public, scientific and regulatory concern over the possible adverse health effects of chronic exposure to trace levels of persistent organic pollutants. The class of compounds made up of the polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF), often collectively known as dioxins, has received widespread attention and attracted a ...

  • Prevention of dioxins de novo formation by ethanolamines

    Abstract Two inhibitors, triethanolamine (TEA) and monoethanolamine (MEA), were tested for their ability to prevent the de novo formation of polychlorinated dibenzo- p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) on sinter plant fly ash. The amounts of both PCDDs and PCDFs, formed by thermal treatment of the fly ash, decreased when inhibitors were added. Up to 90% reduction of the ...

  • A concept for dioxin and furan abatement in the aluminum industry

    IntroductionDioxins and furans are considered the most toxic substances and are suspected to be highly carcinogen. Once being in the focus of the publicity for emitting these substances a company may face mostly emotional discussions bearing the potential of severe damage of the image of the entire industry. Certainly, dioxins and furans represent quite stable chemical compositions and threaten ...


  • Development of a Dioxin TMDL for the Houston Ship Channel in Texas

    Polychlorinated dibenzo-p-dioxins and dibenzofurans (dioxin) are extremely persistent in the environment, and can affect human health at low concentrations for many years. As a result of dioxin found in fish and crab tissue, a seafood consumption advisory was issued by the Texas Department of Health in September 1990 for the upper portion of Galveston Bay and the Houston Ship Channel System (HSC) ...

  • Advances in analytical techniques for polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and dioxin-like PCBs

    Abstract Analytical techniques for the determination of polychorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF) and dioxin-like PCBs (DLPCB) are reviewed. The focus of the review is on recent advances in methodology and analytical procedures. The paper also reviews toxicology, the development of toxic equivalent factors (TEF) and the determination of toxic equivalent ...

  • Making “the Best” Better: Toward a More Useful Method of Reporting Dioxin and Dioxin-like Compounds

    On October 29, 1999, the U.S. Environmental Protection Agency (EPA) published a final rule on reporting releases of persistent, bioaccumulative, and toxic (PBT) substances under the Toxics Release Inventory (TRI).1 This rulemaking was controversial for a host of reasons, not the least of which was EPA’s decision to create the astonishingly low reporting threshold of 0.1 grams for the newly added ...

  • Capacity estimation and preliminary strategy for reducing the release of dioxins in China

    As a party of the Stockholm Convention on Persistent Organic Pollutants, China must submit its national implementation plan (NIP) for this convention. The strategy and action plan for reducing the release of dioxins in China are the most important components of the NIP. Three problems are key points for developing such strategy and action plan—what are the key sources for applying the best ...

  • Simulating the uncertain effect of active carbon capping of a dioxin polluted Norwegian fjord

    Process‐based multimedia models are frequently utilized to simulate the long‐term impacts of pollutants and to evaluate potential remediation actions that can be put in place to improve or manage polluted marine environments. Many such models are detailed enough to encapsulate the different scales and processes relevant for various contaminants, yet still are tractable enough for analysis ...

  • Levels of dioxins in soil and corn tissues after 30 years of biosolids application

    Detectable levels of dioxins have been reported in biosolids, but very little information is available on the effect of long-term application of biosolids on dioxins accumulation in soil and uptake by plants. We analyzed dioxins in soil and corn tissue samples from field plots after 30 continuous applications of biosolids at 0 (Control), 16.8, and 67.2 Mg biosolids ha−1 yr−1 resulting ...

  • In-Pile thermal desorption for treatment of Dioxin-Contaminated soil in Japan

    Abstract A demonstration of thermal treatment of dioxin-contaminated soil was completed in Japan, under the sponsorship of the Japan Ministry of the Environment. TerraTherm’s proprietary In-Pile Thermal Desorption process was demonstrated to successfully treat the soil to the required standard of 1,000 picograms of 2,3,7,8-tetrachlorodibenzodioxin (TCDD) toxic equivalents (TEQ) per ...

  • Perinatal dioxin exposure in The Netherlands – a long-term follow-up

    In 1987, a cohort study was initiated in the Amsterdam/Zaandam region of The Netherlands to study possible effects of dioxins on development and growth in a population of breastfed children selected after an optimal pregnancy and delivery and birth weight above 2500 grams. Effects on thyroid hormone metabolism, liver, haematology and immunology, and retinol binding protein were found in neonates. ...

  • Paper fibers as a carbon source for the de novo formation of polychlorinated dioxins and furans

    Abstract  The formation of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) from carbon that was produced by the pyrolysis of paper fibers and from wood charcoal was investigated experimentally. Fibers obtained from filter paper were pyrolyzed at 300° and 800°C to produce low- and high-temperature carbon samples. The two types of carbon and wood charcoal were ...


  • Sediment dioxin levels as the basis for risk assessment and human health criteria

    Methods for assessing human health risks and establishing water quality criteria under the Clean Water Act are based on the assumption that fish accumulation of dioxin is correlated with the dissolved phase of the dioxin in the water column by a water-to-fish predictive factor called a bioconcentration factor. However, dioxin does not remain dissolved in the water column to any significant ...
