Polychlorinated biphenyls, or PCBs, were first discovered in Hudson River fish in 1975. General Electric had used the chemical mixtures in manufacturing capacitors at two upstate factories, and discharged approximately 1.1 million pounds of PCBs into the Hudson from 1947-1977.
Contamination of the Hudson by these persistent, possibly carcinogenic compounds created the largest superfund site…
Scientists with the University of Texas School of Public Health have released a study on persistent organic pollutant (POP) levels in the U.S. food supply. The study, published in Environmental Health Perspectives in June, showed that the chemicals are found in the many types of food even though their use has been banned. This study …
Polychlorinated biphenyls, or PCBs, are a widespread class of persistent organic chemicals that accumulate in the environment and humans and are associated with a broad spectrum of health effects. PCBs were widely used as dielectric fluids in transformers, capacitors, and coolants.
The processing and distribution of PCBs has been prohibited in almost all industrial countries …
