2,4,6- Trichlorophenol has been shown to be carcinogenic in animals, producing lymphomas, leukemia, and liver cancer via oral exposure. EPA has classified 2,4,6-trichlorophenol as a Group B2, probable human carcinogen.

Evidence for carcinogenicity to animais (inadequate for pentachlorophenol and 2,4,5-trichlorophenol; sufficíent for 2,4,6-trichlorophenol) Pentachlorophenol was tested in one ex periment in two strains of mice and in one experiment in rats by oral administration at dose levels sufficiently high to cause mild.

2,4,6-trichlorophenol is a trichlorophenol with phenolic substituents on positions 2, 4 and 6. It has a role as a carcinogenic agent. It is a conjugate acid of a 2,4,6-trichlorophenolate. 2,4,6-trichlorophenol appears as yellow to pinkish-orange needles or orange fluffy solid.

In animal models, Bioassay of 2,4,6-trichlorophenol for possible carcinogenicity. book of 2,4,6-trichlorophenol leads to an increased incidence of lymphomas, leukemia, and liver cancer.

National Cancer Institute. Carcinogen Bioassay and Program Resources Branch. Publication date Topics Carcinogens, Pesticides Publisher. Regulatory agencies currently rely on rodent carcinogenicity bioassay data to predict whether or not a given chemical poses a carcinogenic threat to humans.

We argue that it is always more useful to know a chemical's carcinogenic potency (with confidence limits) than to be able to say only qualitatively that it has been found to be a hamptonsbeachouse.com by: May 22,  · The choice of investigation mostly depends on the properties of the drug and/or the specific results obtained from long-term carcinogenicity testing.

A bioassay of hexachlorophene for possible carcinogenicity was conducted by administering the test chemical in feed to Fischer rats. Groups of 24 rats of each sex were administered hexachlorophene at one of three doses, either 17, 50, or ppm, for weeks.

Higher doses of ppm, used in 8-week subchronic. The conventional test for carcinogenicity is the long-term rodent carcinogenicity bioassay described in Organisation for Economic Cooperation and Development (OECD) Test Guideline (TG) The objective of this test is “to observe test animals for a major portion of their life span for the development of neoplastic lesions during or after.

The only investigation of the subchronic oral toxicity to animals of 2,4,6-trichlorophenol was a range-finding experiment by the NCI () preliminary to performing an oral carcinogenicity bioassay.

In this study, groups of five male and five female Fischer rats were fed ad. libitum diets that contained 0, 10, 14, 21, 31, or.

The CAG evaluates substances for possible carcinogenicity according to the procedures outlined in the Agency's Interim Guidelines for Carcinogen Risk Assessment found in Interim Procedures and Guidelines for Health Risk and Economic Impact Assessments of Suspected Carcinogens (41 Fed.

Reg. May 25, ). The minority of the committee believes that the process for selecting doses to be used in a carcinogenicity bioassay should be modified. Specifically, the minority recommends that dose selection be done by a panel of experts on the basis of careful evaluation of appropriate subchronic studies conducted before the bioassay is initiated.

Carcinogenicity (IARC Classification) 2B, possibly carcinogenic to humans. Uses/Sources: 2,4,6-Trichlorophenol has been used as a fungicide, herbicide, insecticide, antiseptic, defoliant, and glue preservative.

Skin contact while treating wood with the tetrachlorophenols is the Accession Number: T3D Although 2,4,6-trichlorophenol is a carcinogen in lifetime rodent studies, no evidence was found for DNA damage in rat liver or the white cells of rat blood. Similiarly no compound related changes were found in serum alanine aminotransferase, hepatic glutathione or cytochrome P content.

Apr 07,  · Hexachloroethane is classified as a possible human carcinogen by IARC and is reasonably anticipated to be a human carcinogen by NTP. The U.S. EPA has established drinking water and other environmental regulations for hexachloroethane. Workplace standards and guidelines for hexachloroethane have been established by OSHA and ACGIH, respectively.
