Carcinogenic and noncarcinogenic polycyclic hydrocarbons in Neurospora crassa and Chinese hamster cells: their photodynamic effects.
The photodynamic effect of polycyclic hydrocarbons was studied in Neurospora crassa and tissue culture cells of the Chinese hamster. The polycyclic hydrocarbons were dissolved in dimethylformamide and added to the treatment solution or medium. Other solvents, such as dimethyl sulfoxide and bovine serum, quenched the photodynamic effect of 3,4-benzpyrene and could not be used. Conidia from a dik...
متن کاملSources, properties and health risks of carcinogenic polycyclic aromatic hydrocarbons
In the present review article focus on highlighting the sources, properties and health risks of carcinogenic PAHs both on human health and environment. Polycyclic Aromatic Hydrocarbons (PAHs) comprises a broad family of compounds that are also described as semi volatile organic compounds (SVOC). This term refers to the fact that PAHs are distributed between gas and particle phases. In fast budd...
متن کاملMutagenic and carcinogenic properties of polycyclic aromatic hydrocarbons.
The rapid development of the chemical industry, combustion of fossil fuels, and smoking of tobacco have resulted in contact of the general population with benzo(a)pyrene and other carcinogenic aromatic hydrocarbons. Persons especially at risk occupationally are those engaged in thermal processing of oil shale, coal, and heavy residual petroleum. It has been shown that polycyclic aromatic hydroc...
متن کاملHigh levels of carcinogenic polycyclic aromatic hydrocarbons in mate drinks.
BACKGROUND Drinking mate has been associated with cancers of the esophagus, oropharynx, larynx, lung, kidney, and bladder. We conducted this study to determine whether drinking mate could lead to substantial exposure to polycyclic aromatic hydrocarbons (PAH), including known carcinogens, such as benzo[a]pyrene. METHODS The concentrations of 21 individual PAHs were measured in dry leaves of ei...
متن کاملEpoxides of carcinogenic polycyclic hydrocarbons are frameshift mutagens.
K-region epoxides of the carcinogens benz[a] anthracene, dibenz[a,h]anthracene, and 7-methylbenz[a] anthracene are mutagenic in strains of Salmonella typhimurium designed to detect frameshift mutagens. Parent hydrocarbons, K-region diols and phenols and some other epoxides are inactive as mutagens in these tests. Polycyclic hydrocarbon epoxides, and other presumed proximal carcinogens, are disc...
