  2. Polychlorinated biphenyl - Wikipedia

    en.wikipedia.org/wiki/Polychlorinated_biphenyl

    PCB warning label on a power transformer known to contain PCBs. Polychlorinated biphenyls (PCBs) are organochlorine compounds with the formula C 12 H 10−x Cl x; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment. [2]

  3. Bioremediation of polychlorinated biphenyls - Wikipedia

    en.wikipedia.org/wiki/Bioremediation_of...

    Bioremediation of PCBs is the use of microorganisms to degrade PCBs from contaminated sites, relying on multiple microorganisms' co-metabolism. Anaerobic microorganisms dechlorinate PCBs first, and other microorganisms that are capable of doing BH pathway can break down the dechlorinated PCBs to usable intermediates like acyl-CoA or carbon ...

  4. Globally Harmonized System of Classification and Labelling of ...

    en.wikipedia.org/wiki/Globally_Harmonized_System...

    Product identifier (ingredient disclosure): Name or number used for a hazardous product on a label or in the SDS. The GHS label for a substance should include the chemical identity of the substance. For mixtures, the label should include the chemical identities of all ingredients that contribute to acute toxicity, skin corrosion or serious eye ...

  5. Dioxins and dioxin-like compounds - Wikipedia

    en.wikipedia.org/wiki/Dioxins_and_dioxin-like...

    PCB-compounds, always containing low concentrations of dioxin-like PCBs and PCDFs, were synthesized for various technical purposes (see Polychlorinated biphenyls). They have entered the environment through accidents such as fires or leaks from transformers or heat exchangers, or from PCB-containing products in landfills or during incineration.

  6. GHS hazard pictograms - Wikipedia

    en.wikipedia.org/wiki/GHS_hazard_pictograms

    an identification of the product; a signal word – either Danger or Warning – where necessary; hazard statements, indicating the nature and degree of the risks posed by the product; precautionary statements, indicating how the product should be handled to minimize risks to the user (as well as to other people and the general environment)

  7. Kalamazoo Superfund Site - Wikipedia

    en.wikipedia.org/wiki/Kalamazoo_Superfund_Site

    Polychlorinated biphenyls (PCB) constitute a wide array of now-banned organic chemicals with a variety of industrial applications. At the Kalamazoo River site, most PCBs are a result of the recycling of carbonless copy paper during the 1970s, the waste products from which were dumped into the river.

  8. HAZMAT Class 9 Miscellaneous - Wikipedia

    en.wikipedia.org/wiki/HAZMAT_Class_9_Miscellaneous

    Any material that meets the definition in 49 CFR 171.8 for an elevated temperature material, a hazardous substance, a hazardous waste, or a marine pollutant. A new sub-class, class 9A, has been in effect since January 1, 2017. This is limited to the labeling of the transport of lithium batteries.

  9. Warren County PCB Landfill - Wikipedia

    en.wikipedia.org/wiki/Warren_County_PCB_Landfill

    The Warren County PCB landfill was permitted as a "dry-tomb" toxic waste landfill by the EPA under the Toxic Substances Control Act. The EPA approved the "dry-tomb" PCB landfill which failed from the beginning because it was capped with nearly a million gallons of water in it.
