Hexachlorobenzene (HCB) residues in fish
Bulletin of Environmental Contamination and Toxicology, 1974Analysis of fish collected by the U.S. Fish and Wildlife Service for the fall 1970 National Pesticide Monitoring Program detected the presence of a compound eluting with, and subsequently identified incorrectly as B-benzenehexachloride. This compound was frequently observed when Florisil cleanup was used in the analysis of organochlorine residues in ...

Effect of hexadecane on the pharmacokinetics of hexachlorobenzene
Toxicology and Applied Pharmacology, 1984Sixty rats were divided into two groups; one group received normal Rat Chow and the other the same feed supplemented with 5% hexadecane. Twenty-four hours later, the rats were injected iv with 1.0 mg/kg [14C]hexachlorobenzene (HCB). For 1 month after dosing, the activity of 14C was determined in various tissues and in serum at predetermined intervals ...

Hexachlorobenzene (HCB): A review
Environmental Research, 1979Current knowledge about hexachlorobenzene (HCB) is reviewed. HCB is not a naturally occurring compound and is known to accumulate in both terrestrial and marine animals. The toxicity to human beings of long-term low level exposure to HCB is discussed. The occurrence of HCB in humans, food, wild mammals, birds, fish, and soil is described.

Perinatal hexachlorobenzene toxicity in the mink
Environmental Research, 1983Adult female standard dark mink were exposed to hexachlorobenzene (HCB) at concentrations of 0, 1, and 5 ppm in the feed and bred with males on the same treatments. Female offspring were allowed to mature to 16-17 weeks and killed. At 16-17 weeks of age, HCB had no effect on body weights or liver weights.

Subacute toxicity of hexachlorobenzene in the rat
Toxicology and Applied Pharmacology, 1977Abstract Male and female rats of the Charles River strain were fed a commercial diet supplemented with 5% corn oil. Hexachlorobenzene (HCB) was added to the corn oil to give 0, 0.5, 2, 8, or 32 mg of HCB/day/kg/body weight. Subgroups of four rats of each sex were killed at 3, 6, 9, 12, and 15 weeks of feeding.

Abstract Hexachlorobenzene (HCB), formerly used as a seed fungicide, is a persistent pollutant that accumulates in the environment, in animals, and in humans. HCB disrupts the porphyrinheme biosynthetic pathway, resulting in porphyria attended by photosensitivity, skin lesions, and liver pathology.

A genotoxicological study of hexachlorobenzene and pentachloroanisole
Teratogenesis, Carcinogenesis, and Mutagenesis, 1991AbstractThe potential mutagenic activity of hexachlorobenzene (HCB) and pentachloroanisole (PCA) was investigated. No genotoxicity after application on Salmonella typhimurium (Ames test), Escherichia coli, and human peripheral blood lymphocytes in vitro was observed.

Autoimmune Effects of Hexachlorobenzene in the Rat
Toxicology and Applied Pharmacology, 1993We investigated whether autoimmune disregulation underlies the formerly reported induction of IgM hypergammaglobulinemia and lymphoid organ enlargement by hexachlorobenzene (HCB) in rats. To this end blood, liver, and lymphoid organs were collected from male Wistar rats after feeding a semisynthetic diet containing 0, 500, or 1000 mg HCB/kg for 3 weeks.

Oncogenicity of hexachlorobenzene.
IARC scientific publications, 1987Subchronic and chronic toxicities of hexachlorobenzene (HCB) were studied in both sexes of Swiss mice, Syrian golden hamsters and Sprague-Dawley rats, at dietary dosages of 0, 100 and 200 ppm (mice), and 0, 200 and 400 ppm (hamsters and rats) for 90 days. At day 91, 25/50 animals in each of 18 groups were killed for histology studies.
