New approaches for monitoring PAH exposures at the H-Coal demonstration plant. [Polycyclic aromatic hydrocarbons screening procedure based on synchronous luminescence and room temperature phosphorescence]
This paper describes a number of recently developed techniques that were used to characterize fugitive emissions of airborne polynuclear aromatic hydrocarbons (PAH) at the H-Coal Pilot Plant in Catlettsburg, Kentucky. Both area and personnel samples were collected and analyzed. A portable derivative uv absorption spectrometer was used to monitor volatile PAH species such as naphthalene, methylnaphthalene, and indan. Vapors of higher molecular weight PAH such as phenanthrene, pyrene, and fluoranthene were monitored using a new passive personnel monitor recently developed for PAH vapors. Air particulate samples were solvent extracted and ranked according to their PAH content using a cost-effective screening procedure based on synchronous luminescence (SL) and room temperature phosphorescence (RTP). The results of SL/RTP ranking were compared with data obtained by traditional methods such as gas chromatography/mass spectrometry (GC/MS). The results of this study demonstrate that the SL and RTP techniques provide a rapid, efficient, and cost-effective screening procedure to monitor PAHs in workplace environments. The correlations between the SL/RTP and GC/MS data indicate that the screening procedure has a ranking capability appropriate even for samples whose differences in PAH content are much less than one order of magnitude. 12 references, 5 figures, 2 tables.
