Hexachlorobenzene porphyria and hexachlorobenzene catabolism in rats

Biochemical and Biophysical Research Communications, 1978
Gas-chromatographic examinations were made on the amounts of hexachlorobenzene accumulating in the liver and fatty tissue of rats chronically poisoned with a diet containing 0.2 % hexachlorobenzene, and on the amounts of hexachlorobenzene and pentachlorophenol excreted with the urine and the faeces in the course of the poisoning.

Dissociative Electron Attachment to Hexachlorobenzene

ChemPhysChem, 2022
AbstractGas phase molecules of hexachlorobenzene (C6Cl6) were investigated by means of dissociative electron attachment spectroscopy (DEAS). Three channels of molecular negative ions decay have been identified: abstraction of Cl− and Cl2− as well as electron detachment (τa∼250 μs at 343 K). All three channels exhibit temperature dependence.

Global hexachlorobenzene emissions

Chemosphere, 2001
Information from a variety of sources has been assembled to give a global picture of hexachlorobenzene (HCB) emissions in the mid 1990s. No single overwhelming source of HCB was identified. The best estimates of global HCB emissions from different categories of sources are as follows: pesticides application - 6500 kg/yr; manufacturing - 9500 kg/yr ...

Biomonitoring equivalents for hexachlorobenzene

Regulatory Toxicology and Pharmacology, 2010
Recent efforts worldwide have resulted in a growing database of measured concentrations of chemicals in blood and urine samples taken from the general population. However, few tools exist to assist in the interpretation of the measured values in a health risk context.

Hexachlorobenzene toxicity in pigs

Toxicology and Applied Pharmacology, 1978
Hexachlorobenzene Toxicity in Pigs. den Tonkelaar, E. M., Verschuuren, H. G., Bankovska, J., de Vries, T., Kroes, R., and van Esch, G. J. (1978). Toxicol. Appl. Pharmacol. 43 , 137–145. A 90-day toxicity study was carried out in which pigs received 0.05, 0.5, 5.0, and 50 mg/kg/day of hexachlorobenzene (HCB).

Intestinal excretion of hexachlorobenzene

Archives of Toxicology, 1981
1. The intestinal excretion of hexachlorobenzene (HCB) was studied in rats using the method of pendular perfusion. One and four weeks after i.p. application of 100 micrograms HCB/kg body weight segments of jejunum, ileum and colon were perfused with light liquid paraffin or squalane for 5 h. 2.

Hexachlorobenzene (HCB) residues in fish

Bulletin of Environmental Contamination and Toxicology, 1974
Analysis 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 ...

Public health assessment of hexachlorobenzene

Chemosphere, 2001
Recently, hexachlorobenzene (HCB) was proposed for inclusion in the system of toxicity equivalency factors (TEFs) currently used for dioxin-like compounds. In this paper, we explore the practical implications of the proposition to the Agency for Toxic Substances and Disease Registry (ATSDR) programs by comparing respective health guidance values for 2 ...

Hexachlorobenzene (HCB): A review

Environmental Research, 1979
Current 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.

Carcinogenesis of hexachlorobenzene in mice

International Journal of Cancer, 1979
AbstractHexachlorobenzene (HCB) is a fungicide and a by‐product in the manufacture of many chlorinated solvents and pesticides. In Turkey, between 1955 and 1959 HCB was the causative agent of an epidemic of toxic porphyria, which involved more than 3,000 people, predominantly children.
