Predicting the carcinogenic potential of environmental nitropyrenes
Environmental and Molecular Mutagenesis, 1987AbstractNitrated polycyclic aromatic hydrocarbons (nitroarenes) constitute a large group of anthrapogenic environmental contaminants. Some members of the group are mutagenic and genotoxic in a wide spectrum of systems while others are either mutagenic only in Salmonella typhimurium or devoid of activity altogether.

Evaluation of Environmental Carcinogens for Cancer in Man
Oncology, 2009The problem of the presence of carcinogens in the environment has become of considerable concern to the public, as it has been to the biomedical community for some time. The burden of identifying carcinogenic agents and determining threshold levels, if they exist, falls upon the scientific community.

Environmental chemical carcinogens and liver cancer
Journal of Toxicology and Environmental Health, 1979An appraisal is made of these chemical carcinogens available in the human environment that have been implicated in the etiology of liver cancer. The possible role of mycotoxins is discussed in detail, in particular the association between the aflatoxins and liver cancer in Africa and the Far East.

[A carcinogens--methods for detecting environmental muta/carcinogens].
Gan to kagaku ryoho. Cancer & chemotherapy, 1985The major causes of cancer in the developed countries are now thought to be environmental or man-made factors. Because most carcinogens are also mutagens, the detection and identification of muta/carcinogens to humans seem to be very important in the environmental sciences.

New environmental carcinogens in daily life
Trends in Pharmacological Sciences, 1988Abstract It is well known that the incidence of cancer is related to environmental factors such as diet, smoking and occupation. In this article , Takashi Sugimura reviews evidence that metabolites of heterocyclic amines found as contaminants in cooked or charred food are involved in the first stage of carcinogenesis — tumor initiation.

Nitrosamines as potential environmental carcinogens in man
Clinical Biochemistry, 1990Nitrosamines are ubiquitous in our environment and diet. Many nitroso compounds are carcinogenic in animals and most probably in man. Nitrosamines are formed from the reaction of nitrite with primary, secondary, or tertiary amines in an acid medium. Nitrate should be considered as a nitrosating agent because it can be converted to nitrite by microbial ...

Viruses as Environmental Carcinogens: An Agricultural Perspective
1982Under natural circumstances tumor viruses can be considered as risk factors which in themselves are neither necessary nor sufficient to produce cancer; they may do so, however, if provided with suitable genetic and environmental conditions. It follows that a reduction in amount of virus or other environmental cofactors may prevent the associated tumors.
