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.
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.
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 ...
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.
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 ...
an identification of the product; a signal word – either Danger or Warning – where necessary; hazard statements, indicating the nature and degree of the risks posed by the product; precautionary statements, indicating how the product should be handled to minimize risks to the user (as well as to other people and the general environment)
Warren County PCB Landfill was a PCB landfill located in Warren County, North Carolina, near the community of Afton south of Warrenton. The landfill was created in 1982 by the State of North Carolina as a place to dump contaminated soil as result of an illegal PCB dumping incident.
