Influences of Waste Iron Residue on Combustion Efficiency and Polycyclic Aromatic Hydrocarbons Release during Coal Catalytic Combustion

Occupational exposure to polycyclic aromatic hydrocarbons during Diesel combustion.

Identification and determination of polycyclic aromatic hydrocarbons (PAHs) in Diesel exhaust in the working environment and assessment of workers' occupational exposure to these suspected human carcinogens were the aim of this experimental investigation. The range of exposure factors calculated on the basis of 9 individual PAH concentrations determined in personal air samples shows that time-a...

Coal Combustion and Combustion Products

Bioavailability and potential carcinogenicity of polycyclic aromatic hydrocarbons from wood combustion particulate matter in vitro.

Due to increasing energy demand and limited fossil fuels, renewable energy sources have gained in importance. Particulate matter (PM) in general, but also PM from the combustion of wood is known to exert adverse health effects in human. These are often related to specific toxic compounds adsorbed to the PM surface, such as polycyclic aromatic hydrocarbons (PAH), of which some are known human ca...

Structural characteristics of polycyclic aromatic hydrocarbon isomers in coal tars and combustion products.

4 Isomeric polycyclic aromatic hydrocarbons (PAH) with two to six rings in coal-derived products and in a carbon black were separated, identified, and quantified by using capillary column gas chromatography and gas chromatography-mass spectrometry. A newly synthesized smectic liquid-crystalline polysiloxane and a conventional polymethylsiloxane were utilized as stationary phases. Many previousl...

Polycyclic Aromatic Hydrocarbons and Other Organic Compounds in Ashes from Biomass Combustion

Power generation from biomass is a substantial source of ashes, the extent of which depends on the type of biomass fuel and technology of combustion being used. The current study focuses on comparison of ashes with a special emphasis on hazardous organic compounds, particularly the polycyclic aromatic hydrocarbons (PAHs) fraction, present in ash. The reason is that ashes from combustion of wood...
