Sources, 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 کاملPhotochemistry of polycyclic aromatic hydrocarbons in cosmic water ice
Context. Mid-infrared emission features originating from polycyclic aromatic hydrocarbons (PAHs) are observed towards photon dominated regions in space. Towards dense clouds, however, these emission features are quenched. Observations of dense clouds show that many simple volatile molecules are frozen out on interstellar grains, forming thin layers of ice. Recently, observations have shown that...
متن کاملSmoking increases carcinogenic polycyclic aromatic hydrocarbons in human lung tissue.
Tobacco smoke is a major source of human exposure to polycyclic aromatic hydrocarbons (PAHs). The concentration of PAHs in lung tissue would reflect an individual's dose, and its variation could perhaps reflect cancer risk. Eleven PAHs were measured in 70 lung tissue samples from cancer-free autopsy donors by gas chromatography-mass spectrometry. There were 37 smokers and 33 nonsmokers as estim...
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...
