NCIt definition : A stable, white, crystalline chlorinated hydrocarbon that emits very toxic fumes of
carbon monoxide, carbon dioxide, hydrochloric acid and other chlorinated compounds
when heated to decomposition. Hexachlorobenzene was used as a fungicide and was also
used as a chemical intermediate in the manufacture of dyes, synthesis of organic chemicals,
rubber and in wood preservation. Prolonged oral exposure to this substance results
in a liver disease with associated skin lesions. Hexachlorobenzene is reasonably anticipated
to be a human carcinogen based on association between thyroid, liver and kidney cancer
and oral exposure in animals. (NCI05);
