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 ...

4. Mobile phone recycling - Wikipedia

   en.wikipedia.org/wiki/Mobile_phone_recycling

   Mobile phones typically contain the following components: printed circuit board (PCB), liquid crystal display (LCD), camera, flexible substrate and motor, and speaker and microphone. [7] These components are made from hazardous, precious, and base elements. [7] The PCB is made of lead, arsenic, gold, silver, copper, aluminum, and other base ...

   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 ...

7. Recycling codes - Wikipedia

   en.wikipedia.org/wiki/Recycling_codes

   Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.

8. Warren County PCB Landfill - Wikipedia

   en.wikipedia.org/wiki/Warren_County_PCB_Landfill

   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 ...

9. 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.
