Capillary gas chromatography of polychlorinated benzonitriles (PCBN)

open access: yesFresenius' Journal of Analytical Chemistry, 1997
Polychlorinated benzonitriles (PCBN) are products of combustion chemistry and can be emitted from municipal waste incinerators. Their possible relevance to environmental chemistry has not previously been described, with the exception of the herbicide 2,6-dichlorobenzonitrile.
