Remediation Of Polychlorinated Biphenyl (Pcb) Contaminated Building Materials Using Non-Metal And Activated Metal Treatment Systems, Tamra Legron-Rodriguez
Remediation Of Polychlorinated Biphenyl (Pcb) Contaminated Building Materials Using Non-Metal And Activated Metal Treatment Systems, Tamra Legron-Rodriguez
Electronic Theses and Dissertations
PCBs are recalcitrant compounds of no known natural origin that persist in the environment despite their ban by the United States Environmental Protection Agency in 1979 due to negative health effects. Transport of PCBs from elastic sealants into concrete, brick, and granite structures has resulted in the need for a technology capable of removing these PCBs from the materials. This research investigated the use of a nonmetal treatment system (NMTS) and an activated metal treatment system (AMTS) for the remediation and degradation of PCBs from concrete, brick, and granite affixed with PCB-laden caulking. The adsorption of PCBs onto the components …

Electronic Theses and Dissertations
Polychlorinated biphenyls (PCBs) are a class of environmentally persistent halogenated organic compounds that were once used as stabilizers to improve the properties of a variety of materials such as lubricants, heat transfer fluids, paints, and caulking materials. PCBs are also capable of migration through processes such as spillage into soils, leaching into groundwater, and volatilization into the atmosphere. Although banned in 1979 over health concerns, PCBs persist in these materials to this day because they are resistant to biotic degradation and natural weathering processes. The wide variety of contaminated materials means that many existing treatment options cannot be used across …
