  • 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 ...


  • Determination of Dioxins and Furans in Soil using the SpeedExtractor E-916

    Polychlorinated dibenzo dioxins (PCDDs) and polychlorinated dibenzo furans (PCDFs) are persistent organic pollutants (POPs) banned by the Stockholm Convention and they are therefore monitored worldwide. PCDDs and PCDFs were extracted from a soil sample with the SpeedExtractor E-916 and an ASE 200 system (Dionex) according to the U.S. EPA Method 3545A. Dioxin and furan congeners were determined by ...

  • Development of a highly sensitive assay for enzyme‐mediated reductive degradation of polychlorinated dibenzo‐p‐dioxin

    The degradation of 2‐chloro‐4,5‐O‐(4′‐methyl‐7′, 8′‐diphenyl)ether (CMDPE), an analog of 2,7‐dichlorodibenzo‐p‐dioxin (2,7‐DCDD), mediated by Geobacillus sp. UZO 3 cell‐free extract was monitored. Ethyl acetate extracts of a complete reaction mixture incubated at 65°C for 18 h were analyzed either by thin layer chromatography (TLC) fractionation coupled with spectrometric detection or by gas ...

  • Guidelines for the use of mosses and soils in monitoring contaminant fallout

    In 1999 Italy’s Environmental Protection Agency (ANPA) published a paper on the methods to be used in the case of mosses and soils. After nearly a decade, a review is advisable. The attached Guidelines take account of numerous experiments in the environmental field and include a short description of bryophyte biology. A great many pollutants are present in our environment. In addition to ...

  • Extracting PCDD/F from Soil and Grass Samples

    We are presenting the use of BÜCHI's Extraction Unit B-811 for isolating polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) from solid environmental samples (soil, grass) under standard conditions and by means of hot extraction. The extracts received will be further processed by means of an internationally recognized method and analyzed with high-resolution GC/MS in the single-ion ...

  • Car Engines Air Filters. A Useful Ambient Air Sampler and/or a Possible Hazardous Waste?

    Car-engine air filters (CAFs) have been recently used as inexpensive alternative air sampling media for hydrophobic organic compounds such as polycyclic aromatic hydrocarbons, polychlorinated dibenzo-p-dioxins and furans and also for heavy metals. This “active-passive” sampling methodology is a promising way for urban air monitoring, being able to offer invaluable advantages. Two ...

  • Surface plasmon resonance biosensors for environmental analysis: general aspects and applications

    Interest in the development of Surface Plasmon Resonance (SPR) based biosensors for the detection and monitoring of analytes in several fields has been extensively developed in the last decade. Indeed, SPR-based biosensors demonstrate interesting potential for environmental applications, and a substantial number of studies have been reported for heavy metals, dioxins, pesticides, aromatic ...

  • Analysis of PCBs in emission samples: non ortho, mono-ortho and homolog totals by level of chlorination

    Polychlorinated biphenyls (PCBs) are one of the most widespread persistent organic pollutants, identified in every component of the global ecosystem. A production of approximately 2 * 10 9 Kg technical PCB occurred form 1930 to the late 1970 1 and the total amount released into the environment is estimated in 370. 000 2 tonnes. Twelve of the possible 209 PCBs are non- and mono-ortho substituted ...

  • New boiler MACT and affiliated rules proposed

    EPA proposed three related rules (with final rules expected by December 16, 2010), intended to reduce the emission of hazardous air pollutants (HAPs) from industrial, commercial, and institutional boilers and process heaters as well as commercial and industrial solid waste incinerators. Simultaneously, it also proposed a definition of solid waste that could potentially affect some units currently ...

  • Trends of Chlorinated Organic Contaminants in Great Lakes Trout and Walleye from 1970 to 1998

    Abstract  Levels of chlorinated organic contaminants in predator fish have been monitored annually in each of the Great Lakes since the 1970s. This article updates earlier reports with data from 1991 to 1998 for lake trout (Salvelinus namaycush) and (Lake Erie only) walleye (Sander vitreus) to provide a record that now extends nearly 30 years. Whole fish were analyzed for a number of ...

  • A Case Study in Implementation of the National Emission Standard for Hazardous Air Pollutants for the Portland Cement Industry at a Major Source

    The regulations at 40 CFR 63, Subpart LLL are commonly known as PC MACT because the rule establishes the maximum available control technology for hazardous air pollutants (HAPs) from portland cement plants in the United States. There are 188 HAPs specified in Section 112 of the Clean Air Act Amendments of 1990. Two classifications of HAP emitters are specified in 40 CFR 63. Major sources of HAPs ...
