Polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) belong to a group of compounds that are structurally related and are environmentally and biologically persistent. These chemicals have a tendency to bioaccumulate and biomagnify in the food chain. Jun 28, · Polychlorinated biphenyls (PCBs) are organic molecules that are stable in nature. They were widely used in the early s. PCBs have entered the ecosystem due to their wide applications via legal and illegal use. Due to its insoluble nature, these environmental contaminants are persistent in the environment, thereby contaminating different Author: Soumya Nair, Jayanthi Abraham.
Polychlorinated biphenyls are a group of different chemicals which share a common structure but vary in the number of attached chlorine atoms. An estimated million pounds of different types of PCBs were dumped into the Hudson River by General Electric from until , when they were banned. Jun 28, · Synthetic chlorinated organic compounds—polychlorinated biphenyls (PCBs)—have been used in several industrial applications for over 50 years and are among the most persistent classes of xenobiotic pollutants. PCBs remain in the environment for a long period due to their low reactivity and stability in harsh environmental esthetic-tokyo.com: Seethalaksmi Elangovan, Sathish Babu Soundra Pandian, S J Geetha, Sanket J.

Jan 07, · PCBs, or polychlorinated biphenyls, are industrial products or chemicals. PCB contamination is high in the Housatonic River and New Bedford Harbor in Massachusetts. PCBs were banned in the U.S. in amid suggestions that these chemicals could have unintended impacts on human and environmental health.
Polychlorinated biphenyl definition is - any of several compounds that are produced by replacing hydrogen atoms in biphenyl with chlorine, have various industrial applications, and are toxic environmental pollutants which tend to accumulate in animal tissues —called also PCB.
Polychlorinated biphenyls (PCBs) have been produced commercially since be fore They proved to be highly versatile mixtures and their uses continued to expand during the early 's even after the unanticipated world-wide en vironmental contamination had been discovered (Jensen et aI.
Polychlorinated biphenyls (PCBs) are a class of chlorinated organic chemicals that are used for a variety of industrial and commercial purposes. Polychlorinated biphenyls (PCBs) are a group of man-made organic chemicals and have been widely used as coolants and lubricants in transformers, capacitors, and other electrical equipment.
Food contamination is probably the single most significant source of human exposure. Studies in humans and animals have indicated that neurological development is one of the primary targets of PCBs. May 22, · Polychlorinated biphenyls (PCBs) are industrial chemicals that were manufactured from until when they were banned.
