In June 2020, State Impact of Pennsylvania stated that "In 1979, the EPA banned the use of PCBs, but they still exist in some products produced before 1979. They persist in the environment because they bind to sediments and soils. High exposure to PCBs can cause birth defects, developmental delays, and liver changes." [10]
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 ...
From 1960 to 1970, the site consisted of seven waste disposal lagoons and open storage of 10,000 to 15,000 drums. Testing of groundwater found it to contain volatile organic compounds (VOCs). Soil sampling identified VOCs, phthalates, polychlorinated biphenyls (PCBs), and metals including lead and chromium. [11] 12/30/1982: 09/08/1983: 07/13 ...
(Reuters) -A Washington jury on Tuesday ordered Bayer to pay $100 million to four people who say they were sickened by toxic chemicals known as PCBs at a Seattle-area school, but found the company ...
Test results conducted in the fall showed the presence of PCBs, or polychlorinated biphenyls — toxic, man-made chemicals that were banned from being produced in the United States in 1979 ...
[1] [58] The daily intake of dioxins and dioxin-like PCBs as TEQ is of the order of 100 pg/day, i.e. 1-2 pg/kg/day. [1] In many countries both the absolute and relative significance of dairy products and meat have decreased due to strict emission controls, and brought about the decrease of total intake.

The PCBs came from the company's two capacitor manufacturing plants at Hudson Falls and Fort Edward, New York. [1] The U.S. Environmental Protection Agency (EPA) banned the manufacture of PCBs in 1979. [9] The bulk of the PCBs in the river were manufactured by Monsanto Co. under the brand names Aroclor 1242 and Aroclor 1016. [10]
