hierarchical_section_title: Polychlorinated carbazoles
context_page_description: Polychlorinated carbazoles are a group of chlorinated organic compounds. They are derivatives of carbazole and nitrogen analogues of polychlorinated dibenzofurans.
  Polychlorinated carbazoles usually occur as a mixture of various isomers. This mixture can have a certain frequency pattern from which conclusions can be drawn about the causes of formation.
  PCCZs are not manufactured purposefully. They are formed under certain conditions as by-products of thermal processes. In environmental samples, mixed halogenated carbazoles are also found.
