Reviews on Environmental Health, 1979
The study of bracken carcinogenicity affords an interesting example of the close alliance, with mutual benefit, between the work of veterinarians in the field and experimental research. On the one hand was the condition found in many parts of the world of bovine enzootic haematuria with uncertain aetiology and, on the other, the investigations ...

Dietary Carcinogens and Anti-Carcinogens
Journal of Toxicology: Clinical Toxicology, 1984The scientific understanding of cancer and degenerative disease is being aided by new methodologies which are now used to approach the problem of environmental and occupational carcinogens and anticarcinogens. This paper reviews these powerful new tools and relates them to "natural" mutagens and carcinogens in food.

Risk Analysis, 1992
Human populations are generally exposed simultaneously to a number of toxicants present in the environment, including complex mixtures of unknown and variable origin. While scientific methods for evaluating the potential carcinogenic risks of pure compounds are relatively well established, methods for assessing the risks of complex mixtures are ...

Pharmacology & Toxicology, 1993
Abstract: Air pollution has been recognized as a cancer risk for many years. More than 2,800 different chemicals have been identified in the air or emission sources. Only about 10% of these chemicals have been evaluated in bioassays for genetic or carcinogenic effects.

The induction of cancer by chemicals is a multiple-stage process. Acrylamide is carcinogenic to experimental mice and rats, causing tumors at multiple organ sites in both species when given in drinking water or by other means. In mice, acrylamide increased the incidence and multiplicity of lung tumors and skin tumors.

Mutagens, Carcinogens, and Anti-Carcinogens
1982Mutagens and carcinogens in the environment represent a potential hazard, and it is important to screen large numbers of compounds and mixtures of compounds to which humans are exposed. However, it is Impractical for both technical and monetary reasons to do the bulk of mutagen screening by using mammals.

Carcinogens and Anticarcinogens
1986There is the potential for major progress in the prevention of cancer in the next 5 or 10 years. In the short term, progress in the prevention of cancer depends on a better understanding of some of the risk factors and antirisk factors for the major human cancers.

There are data that show that under the influence of chemical carcinogens of various classes (polycyclic aromatic hydrocarbons, nitroso compounds, aromatic amines), mutagens, ionizing radiation, extremely low frequency radio waves, constant illumination, tobacco smoking, the development premature hotmonal-metabolic disturbances in the main homeostatic ...
