“…Eie and Sǿrlie (n.d.) documented total PAH content in 10 pitch blends of approximately 2-9%, and Skogland (1991) documented PAH content in pitch as high as 14%. PAHs are volatilized from coal tar pitch in prebake smelters during anode baking and in Söderberg smelters when the anode temperature is raised to the required temperature for the electrolytic process to proceed Eie and Sǿrlie, n.d.;Mannweiler et al, 1997;Skogland, 1991;Thrane, 1987). Principal emission sources at aluminum smelters are anode baking furnaces in the prebake method and potroom roof vents and dry or wet scrubbers from both Söderberg and prebake processes (Skogland, 1991).…”

This article provides a description of the processes used in modern aluminum reduction plants and explores the sources of polycyclic aromatic hydrocarbons (PAHs) at pertinent steps in the industrial process. Chemical and physical characteristics of raw and processed source materials are described, and the effects of process modifications and alternative processes on generation of PAHs are explored. For example, the self-bake Söderberg method is contrasted with the prebake method of anode formation by describing the quantities of PAHs generated and characteristics of PAHs associated with each process. Available datasets for aluminum smelters are predominantly limited to analyses of selected parent PAHs (unsubstituted). Thus, many preferred forensic methods for characterizing PAHs cannot be applied to much of the existing data. However, typical parent PAH distributions and isomer ratios are explored using up to 17 selected unsubstituted PAHs in emissions from aluminum reduction plants and environmental media affected by emissions. In addition, summaries are presented of selected environmental studies conducted in areas influenced by aluminum reduction and non-aluminum reduction sources of PAHs. Forensic tools for identifying influences from aluminum smelters in environmental samples reflecting mixed sources are also discussed.

“…Aluminum production is also a source of PAH emissions, and PAH ambient air concentrations were determined in four residential areas close to aluminum industries (56). The results indicated that PAH concentrations were high compared to levels in other polluted areas with industry and dense traffic.…”

Polycyclic aromatic hydrocarbons (PAH) emitted from fluidized bed combustion have been reviewed. Firstly, the PAH origin is undertaken. Secondly, the state of the art on their sampling and analytical procedures are commented. Finally, the influence of the fuel, fossil and nonfossil fuels, the combustor type and the combustion variables are analyzed concerning PAH formation and emission in solid/ gaseous phase.

“…Inexplicably, they are shifted to shorter wavelengths in Hollas's spectrum, although the distance between them is equal in both spectra. (Arey et al, 1989;Graedel, 1978;Graedel et al 1986;Krustulovic et al, 1977;Thrane, 1987Thrane, , 1988.…”

Naphthalene (CioHs), several other hydrocarbons, mostly derivates of naphthalene, and bromine oxide (BrO) were analyzed for narrow band (~<0.01 nm) absorption lines in the wavelength range between 307.7 and 308.3 nm to study their potential impact on OH radical measurements by differential absorption spectroscopy.Only naphthalene showed narrow band absorption lines in this wavelength region. From nine naphthalene lines the differential absorption cross-section a' was determined.The strongest naphthalene line at 308.002 nm is close to the Qj (2) OH line, but about a factor of 200 weaker (o" = (65.2 + 15.3) x 10 -20 cmZ/molec). The corresponding detection limit for naphthalene is about 15 ppt. We re-evaluated some spectra of our OH measurement campaign in July 1987 with respect to naphthalene and obtained an upper limit of 30 ppt for its concentration.BrO was recorded in the larger wavelength interval between 307.7 and 308.7 nm. Structured absorptions were only observed at wavelengths above 308.2 nm and no significant structures were found in the vicinity of the Q1(2) and Q~(3) OH lines.
