The 1100 series was a crude PCB material which was distilled to create the 1200 series PCB product. [ 24 ] The exception to the naming system is Aroclor 1016 which was produced by distilling 1242 to remove the highly chlorinated congeners to make a more biodegradable product. "1016" was given to this product during Monsanto's research stage for ...
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 ...
The PCBs came from the company's two capacitor manufacturing plants at Hudson Falls and Fort Edward, New York. [1] The U.S. Environmental Protection Agency (EPA) banned the manufacture of PCBs in 1979. [9] The bulk of the PCBs in the river were manufactured by Monsanto Co. under the brand names Aroclor 1242 and Aroclor 1016. [10]
Historically, municipal and medical waste incineration was the most important source of PCDD/Fs. 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 ...
The purpose of the Warren County PCB landfill, as the public knew it, was to bury 60,000 tons of PCB-contaminated soil that had been contaminated with toxic PCBs between June and August, 1978, by Robert J. Burns, a business associate with Robert "Buck" Ward of the Ward PCB Transformer Company of Raleigh, North Carolina. Burns and his sons ...
The complaint form attached to NCDOL’s letter to NC State stated that Poe Hall employees “have not been informed of the presence, location and quantity of asbestos-containing materials ...
Most of the waste, however, had a lower PCB concentration and was disposed of at nearby landfills. [ 1 ] Since 1998, EPA, working with Potentially Responsible Parties, has removed nearly 450,000 cubic yards of contaminated material from the site, cleaned up and restored seven miles of the Kalamazoo River and banks, and capped 82 acres worth of ...
"In terms of hazardous waste, a landfill is defined as a disposal facility or part of a facility where hazardous waste is placed or on land and which is not a pile, a land treatment facility, a surface impoundment, an underground injection well, a salt dome formation, a salt bed formation, an underground mine, a cave, or a corrective action ...
