  • Bioremediation of PCB & Pesticide Contaminated Soils Utilizing Gene Expression Factors

     Abstract Historically soils contaminated by persistent organic compounds such as pesticides and PCBs were not considered good candidates for bioremediation due to the simple fact that the chemical industry designed these compounds to withstand the destructive effects of natural attenuation through weathering and microbial activity. Although the chemical industry has long appreciated the ...

  • The 1998 PCB Disposal Amendments: Guide to the 1998 PCB "Mega Rule"

    INTRODUCTION On June 29, 1998, the U.S. Environmental Protection Agency (EPA) promulgated a sweeping series of changes in the PCB regulations under the Toxic Substances Control Act (TSCA). Commonly known as the Mega-Rule or PCB Disposal Amendments (due to its focus largely on waste management issues), this long-awaited rule encompasses more than 80 changes in the regulations and spans more ...

  • B.C. Company Clean PCB Onsite

    A parcel of a land owned by Juker Holdings Ltd on British Columbia's Annacis Island is similar to many other brownfields sites across North America. The former industrial site on 4.3 hectacres contained 3,000 tons of soil contaminated with polychlorinated byphenils from years of copper tubing and related industrial operation. What's different about the Juker site, however, is that it is ...


  • Sonic making inroads on PCB remediation?

    The Sydney Tar Ponds of Nova Scotia are the result of a century of coal mining and steelmaking, which left behind 900,000 tonnes of chemical waste. About 5 per cent or 45,000 tonnes of this waste is contaminated with high levels of PCBs. Two years ago a federal-provincial plan was announced to clean up the Tar Ponds over 10 years at a cost of $400 million, and this led to the creation of the ...

  • Establishing PCB Cleanup Levels for Historical Spills in Texas

    INTRODUCTIONPolychlorinated biphenyls (PCBs) are a mixture of chlorine atoms and biphenyl molecules that combine to form complex chlorinated organic compounds that were manufactured and widely used in the United States from the 1940s through 1978. The chemical characteristics of PCBs made them desirable for use because of their electrical properties and low flammability. Unfortunately, the PCBs ...

  • Method of low temperature pyrolysis as an answer for PCBs utilization.

    When people buy new computers, TV-sets or trendy mobile phones they do not think much about the future of substituted models. In a consumer society where devices are changed due to their obsolescence rather than break down the problem of pollution by e-wastes becomes more relevant. Disposal of printed circuit ...

  • The evaluation of extraction and cleanup methods for the determination of PCB aroclors in caulking and sealing material

    Buildings that were built and/or refurbished before 1977 may well have caulking used to seal masonry joints and windows that contain PCB Aroclor 1254 and/or 1260. The Aroclors were used as a plasticzier and were added to the material to ease application and improve resiliency. The caulking material has been mainly used when there are dissimilar materials, like brick next to concrete, metal window ...


  • Soil Remediation

    Contaminated sites by hazardous substances are a major environmental concern in Europe e throughout the world. Significant financial and human resources are devoted for the remediation of such sites. Many steps have been taken to restrict or ban from use some contaminants (PCBs, IPA, CLB-derivatives) and reduce discharge of others. However, contaminants can persist for many years in soil and ...


  • Effect of plant age on PCB accumulation by Cucurbita pepo ssp. pepo

    Received for publication May 7, 2009. A greenhouse experiment was conducted to investigate polychlorinated biphenyl (PCB) uptake and translocation from soil over time in pumpkin plants (Cucurbita pepo ssp. pepo cv. Howden). Plants were grown in weathered soil collected from a former industrial site contaminated with Aroclor 1248 (mean [PCB]soil = 6.5 mg kg–1). Plants were harvested five times ...
