Applications of polychlorinated biphenyls

Environmental Science and Pollution Research, 2010
In the 50 years or so that polychlorinated biphenyls (PCBs) were manufactured in the USA and elsewhere, they were widely used in numerous applications because of their desirable properties. The purpose of this paper is to review and summarize in one place the factual information about the uses of PCBs, as well as to correct some misconceptions that ...

Advance in bioremediation of polychlorinated biphenyls

Hereditas (Beijing), 2011
As one of the persistent organic pollutants, polychlorinated biphenyls are harmful to the environment and humans. Biodegradation is the most potential way to remove PCBs. Biodegradation can mainly be divided into microbial degradation, phytoremediation, plant and microbial combined remediation.

Polychlorinated biphenyls in the environment

Journal of Chromatography A, 1992
This review surveys the problems arising from the release of PCBs into the environment from the point of view of the analytical chemist. These problems are very complex and interdependent and so it is essential to recognize their mutual links rather than to separate one problem from another (sources of contamination, fate in the environment, toxic ...

Polychlorinated Biphenyls

1964
Publisher Summary Polychlorinated biphenyls (PCBs) are a class of chlorinated organic chemicals that are used for a variety of industrial and commercial purposes. Polychlorinated biphenyl is not a single chemical, but a group of related chemicals. As the relative proportions of individual PCBs varied depending on the intended use of the commercial ...

PCBs (polychlorinated biphenyls) [PDF]

open access: possible, 2001
The chlorinated biphenyls comprise a group of 209 compounds, each consisting of two linked benzene rings with chlorine atoms substituted in different positions (see Figure 11.1). The group is generally referred to as polychlorinated biphenyls (PCBs). To avoid having to use cumbersome chemical names for individual congeners, each is given a number and ...

Hydrodechlorination of polychlorinated biphenyl

Journal of Catalysis, 1978
Abstract The catalytic hydrodechlorination of a complex polychlorinated biphenyl (PCB) mixture was studied in a batch reactor using a 61% Ni on kieselguhr catalyst from 25 to 100 °C at 50 atm of H2. Ethanol was used as a solvent and NaOH as an acid acceptor.

Teratogen update: Polychlorinated biphenyls

Teratology, 1997
Polychlorinated biphenyls, synthetic hydrocarbon compounds once used as hydraulicfluids and lubricants in electrical transformers and capacitors, are among the most ubiquitous and persistent environmental contaminants. Although banned in most Western nations since the 1970s, substantial residues of these compounds persist in air, water, soil, and ...
