IARC: DIESEL ENGINE EXHAUST CARCINOGENIC Lyon, France, June 12, whether through their occupation or through the ambient air. People are exposed not only to motor vehicle exhausts but also to exhausts from other diesel engines, including from other modes of transport (e.g. diesel trains and ships) and from power generators. Given the Working Group’s rigorous, independent assessment of the
synergistic effects (where the effects of a carcinogen is enhanced by exposure to another substance) can increase harm to the body by carcinogens. For example, exposure to Toluene may inhibit the release by the body of Benzene (a known carcinogen) and smoking is known to have a synergistic effect with asbestos exposure
Considerable support exists for the roles of metabolism in modulating the carcinogenic properties of chemicals. In particular, many of these compounds are pro-carcinogens that require activation to electrophilic forms to exert genotoxic effects.
The carcinogenic potential of cobalt and its compounds was evaluated by IARC in 1991,3 which concluded that there was inadequate evidence for carcinogenicity in humans (lung cancer) but sufficient evidence in experimental animals.
Co-carcinogens are chemicals that do not necessarily cause cancer on their own, but promote the activity of other carcinogens in causing cancer. After the carcinogen enters the body, the body makes an attempt to eliminate it through a process called biotransformation .
Abstract: A general overview of the phenolic compounds in food and health is presented, with emphasis on the actual amounts eaten by humans and possible effects on cancer.
Most carcinogens do not develop their carcinogenic effect in a brief exposure. However, they can cause toxic effects in other ways. For instance, acute inhalation of chromium IV com- pounds starts by causing nausea, but can lead to caustic effects on the skin and mucous membranes. For the threat of cancer to exist, long-term exposure to a carcinogen is often necessary. For example, many

Carcinogenic doses of HCAs in rodents have been compared with daily human intake of HCAs , and effects of combination exposures of HCA with other HCAs or other carcinogens also studied . When HCAs having the same target were combined, their effects exceeded the sums of individual data, indicating complexity of risk evaluation. Based on mutational characteristics of HCAs in rodents, the
Common teratogens include ethanol, mercury compounds, lead compounds, phenol, carbon disulfide, toluene and xylene. It should be noted that carcinogenic, mutagenic and teratogenic effects can and do occur and much lower exposure levels than those required to exhibit toxic effects.
Despite the higher affinity of five-ring PAHs to AHR, the differences between toxicological mechanisms of carcinogenic and non-carcinogenic PAHs are largely unknown, as are the interaction effects between individual compounds.
Mutagenic, carcinogenic and cytotoxic effects of several aromatic and olefinic compounds appear to be due to the formation of intermediate epoxides and their reaction with tissue constituents. Whether a given aromatic or olefinic compound produces such an effect would thus depend on a variety of factors, such as the relative rate of formation and degradation of the intermediate oxirane, on its

Abstract. Mechanisms of carcinogenicity are discussed for metals and their compounds, classified as carcinogenic to humans or considered to be carcinogenic to humans: arsenic, antimony, beryllium, cadmium, chromium, cobalt, lead, nickel and vanadium.
The latter were, however, judged to represent non-genotoxic carcinogens with dose thresholds, so that only aflatoxin-like compounds, N-nitroso-compounds and azoxy-compounds were proposed to be excluded from the TTC concept on the basis of their high potency as genotoxic carcinogens, the so-called cohort of concern (COC).

Drinking water standards are set in a different manner for carcinogenic pesticides. For compounds shown to cause cancer in laboratory animals, no NOEL or ADI is set. Current regulatory policy is that there is no specific threshold below which these chemicals do not cause an effect, although this is a matter of considerable scientific controversy. Instead of setting a threshold value, analysis
It is important to be aware of the potential hazards of known carcinogens and to recognize that all chemicals, both organic and inorganic, should be treated with great respect if their thermodynamic and physiological properties are not known. Carcinogenic character is just one of many possible hazards.
