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.
Bioremediation is a waste removal method that uses microorganisms to degrade or remove wastes like organic waste and heavy metal from contaminated sites including both soil and water. The advantages of bioremediation are that it is environment-friendly, inexpensive and can remove multiple wastes simultaneously comparing with traditional ...
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.
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.
Most countries are not on track to eliminate their supplies of highly hazardous compounds called polychlorinated biphenyls (PCBs), contrary to a 2028 deadline established by the Stockholm ...
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 ...
ASR is sometimes differentiated into shredder light fraction and dust. Sometimes these residual materials are called "car-fluff". ASR often contains hazardous substances such as lead, cadmium, and PCB. Therefore, some countries have classified ASR as hazardous waste and have established legislative controls. [1]
