As in the case of the mouse bioassay, interpreting these bioassay results for estimating low-dose human cancer is highly problematic. 4. Challenges interpreting and utilizing the NTP bioassays. In the past four decades many hundreds of chemical agents have been tested for carcinogenicity through standardized bioassays (NRC, ; p. 17). A Cited by: Phenol is a manufactured substance found in a number of consumer products. Skin exposure to high levels of phenol has resulted in liver damage, diarrhea, dark urine, and hemolytic anemia. Phenol has been found in at least of the 1, National Priorities List sites identified by the Environmental Protection Agency (EPA).
Phenol is an aromatic, organic compound. It's structure is formed from six carbon atoms, six hydrogen atoms and one oxygen atom. It has a sweet odour and is a colourless, crystalline solid. Making the formula: C6H6O or C6H5OH. Simply, it can be. Abstract. “All models are wrong, some models are useful”George E.P.

Bisphenol A Carcinogenicity Assessment Research Bisphenol A is not a carcinogen, that is it does not cause or induce cancer in laboratory animals. One of the most thorough studies in this area was performed by the U.S. National Toxicology Program. The earliest reference noted for the estrogenic action of BPA was a report of a bioassay for a positive estrus response, as measured by cornification in vaginal smears, that occurred in ovariectomized rats dosed (route unspecified) twice daily with mg BPA dissolved or suspended in sesame oil on three successive days (Dodds and Lawson, ).

Division of Cancer Cause and Prevention. OCLC Number: Notes: "CAS no. " Description. A bioassay of phenol to test for possible carcinogenicity was conducted by providing this substance in drinking water to F rats and B6C3F1 mice.
Groups of 50 rats and 50 mice of each sex were given drinking water containing 2, or 5, ppm phenol for weeks. As matched controls, groups of 50 rats and 50 mice of each sex received tap water.
A bioassay of p-cresidine for possible carcinogenicity was con ducted using Fischer rats and B6C3F1 mice. p-Cresidine was ad ministered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species.
The dietary con centrations used in File Size: 3MB. A bioassay of technical-grade hydrazobenzene for possible carcinogenicity was conducted using Fischer rats and B6C3F1 mice.
Hydrazobenzene was administered in the feed, at either of two concentrations, to groups of 50 male and 47 to 50 females animals of each species. The committee began meeting in January and selected as its first topic of study and use of the maximum tolerated dose (MTD) in animal bioassays, with emphasis on the relationship between the MTD and the carcinogenic potency of a test chemical.
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, eit 50, or ppm, for weeks. Higher doses of ppm, used in 8-week subchronic.
PHENOL 8. REGULATIONS AND ADVISORIES. The IARC classification for phenol is Group 3, not classifiable with regard to its carcinogenicity to humans (IARC ). The EPA cancer classification for phenol is D, not classifiable as to human carcinogenicity (IRIS ).
The National Toxicology Program has not classified phenol for humanFile Size: KB. Phenol is a colorless or white solid when it is pure; however, it is usually sold and used as a liquid. (1) The odor threshold for phenol is parts per million (ppm), with a strong very sweet odor reported.
(1,7) Phenol is very soluble in water and is quite flammable. (2) The chemical formula for phenol is C 6 H 6. I am answering this question based on my practical work directly with phenol, both in the lab and at industrial reactor scale.
Phenol is in solid state at room temperature with light pink color that melts at around 41 °C. In solid it is in the f. Carcinogenicity Bioassay of Bisphenol A. An Evaluation of the Possible Carcinogenicity of Bisphenol A to Humans.

Because of its anesthetic effects, phenol is used in medicines such as ointments, ear and nose drops, cold sore lotions, throat lozenges. Animal Carcinogenicity Studies: 3.

This carcinogenesis bioassay was conducted according to the usual National Cancer Institute (NCI) protocol, which utilizes an MTD and one-half MOD as the doses for the study.
Mutagenicity The data from mutagenicity tests of aniline are summarized in Table A reason for concern is some evidence that phenol may be genotoxic and the fact that there is insufficient data to discount with certainty the possible carcinogenicity of the compound.
The evaluation must be kept under periodic review. Environment Phenol is not expected to bioaccumulate significantly. REGULATORY TOXICOLOGY AND PHARMACOLOGY 3, () The Power and Interpretation of the Carcinogenicity Bioassay D.
