  2. Polychlorinated biphenyl - Wikipedia

    en.wikipedia.org/wiki/Polychlorinated_biphenyl

    There are 209 different chemical compounds in which one to ten chlorine atoms can replace hydrogen atoms. PCBs are typically used as mixtures of compounds and are given the single identifying CAS number 1336-36-3. About 130 different individual PCBs are found in commercial PCB products. [11]: 2 Toxic effects vary depending on the specific PCB.

  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 ...

    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 ...

    If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Hazmat templates]] to the <includeonly> section at the bottom of that page.

  6. 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.

  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. Occam process - Wikipedia

    en.wikipedia.org/wiki/Occam_process

    The Occam process is a solder-free, Restriction of Hazardous Substances Directive (RoHS)-compliant method for use in circuit board manufacturing developed by Verdant Electronics. It combines the usual two steps of constructing printed circuit boards (PCBs) followed by the population process of placing various leaded and non-leaded electronic ...

  9. Hazardous waste - Wikipedia

    en.wikipedia.org/wiki/Hazardous_waste

    Household Hazardous Waste (HHW), also referred to as domestic hazardous waste or home generated special materials, is a waste that is generated from residential households. HHW only applies to waste coming from the use of materials that are labeled for and sold for "home use". Waste generated by a company or at an industrial setting is not HHW.
