• Because of their longevity, PCBs are still widely in use, even though their manufacture has declined drastically since the 1960s, when a host of problems were identified.
• In electronics, point-to-point construction is a non-automated technique for constructing circuits which was widely used before the use of printed circuit boards (PCBs) and automated assembly gradually became widespread following their introduction in the 1950s.
• In 2014 there was a report of fecal coliform flowing into the lake from a Beaconsfield creek, and of PCBs flowing into it from a Pointe-Claire industrial site.
• In 1978, a transformer manufacturer contracted a trucking company to illegally dump polychlorinated biphenyls (PCBs) alongside roads in North Carolina.
• The Monsanto plant in Sauget was the nation's largest producer of PCBs before a 1977 ban, and the EPA has designated the plant site along Dead Creek as a Superfund site.
• Until they were banned in the US, Sangamo discharged a significant amount of polychlorinated biphenyls (PCBs) into a tributary of the Twelve Mile River which feeds into Lake Hartwell.
• Two of five neighborhoods in Hyde Park appeared to have arsenic, chromium, and dioxin, while all five were found to have PCBs and lead.
• The agency documented high levels of toxic chemicals like dioxin, VOCs, and PCBs in fish as well as soil from the area.
• Sediments at the site contained high levels of polychlorinated biphenyls (PCBs) and heavy metals, which came from old dumps, contaminated industrial sites, combined sewer overflows and disposal of dredged materials.
• In addition there are macroscopic cycles such as the rock cycle, and human-induced cycles for synthetic compounds such as for polychlorinated biphenyls (PCBs).
• After completing graduate school, Fenn's first job was with Monsanto, working in the Phosphate Division and producing polychlorinated biphenyls (PCBs).
• is used in the electrical industry as a gaseous dielectric medium for high-voltage sulfur hexafluoride circuit breakers, switchgear, and other electrical equipment, often replacing oil-filled circuit breakers (OCBs) that can contain harmful polychlorinated biphenyls (PCBs).
• The range of tapes available in the 1950s and 1960s was immense compared with what is available now on the retail market, including RBT (reinforced banding tape), metallic tapes and a tape used for repairing PCBs; E.
• Up until the 1960s they could be eaten, but the State of New York currently recommends against attempting to do so on a regular basis, due to bioaccumulation of PCBs and cadmium that were discovered in the crabs in the 1970s.
• Dumping ROMs from arcade machines, which are highly customized PCBs, often requires individual setups for each machine along with a large amount of expertise.
• Historical industrial use of the river, before the onset of modern environmental laws, has resulted in the degradation of habitat and sediments contaminated with: mercury, dioxins, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and other toxins.
• The surface water was found to be contaminated with mercury whereas the sediments are contaminated with polychlorinated biphenyls (PCBs), pesticides, creosotes, heavy metals (lead, cobalt, and mercury), polycyclic aromatic hydrocarbons (PAHs), chlorinated benzenes, and BTEX compounds (benzene, ethylbenzene, toluene, xylene).
