The International Agency for Research on Cancer (IARC) rendered PCBs as definite carcinogens in humans. According to the U.S. Environmental Protection Agency (EPA), PCBs cause cancer in animals and are probable human carcinogens. [4] Moreover, because of their use as a coolant in electric transformers, PCBs still persist in built environments ...
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 ...

These contaminants enter the environment through both use and disposal. Due to extensive concern from the public, legal, and scientific sectors indicating that PCBs are likely carcinogens and potential to adversely impact the environment, these compounds were banned in 1979 in the United States.

A printed circuit board (PCB), also called printed wiring board (PWB), is a laminated sandwich structure of conductive and insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive ...

Polychlorinated biphenyl, an organic chlorine compound, now recognized as an environmental toxin and classified as a persistent organic pollutant; Printed circuit board, a board used in electronics; Plenum chamber burning, in some jet engines; Papillary carcinomas of the breast, rare forms of the breast cancers
The selected cleanup plan requires the excavation and off-site disposal of contaminated soil from the former mill site. The cleanup work plans were finalized in Sept. 2016, and Pre-Design Investigation work was completed in 2017. Cleanup work will start once EPA approves the work plan, expected in 2018 or early 2019.
