High pressure liquid chromatographic method for routine analysis of major parent polycyclic aromatic hydrocarbons in suspended particulate matter

Polycyclic Aromatic Hydrocarbon Levels and Mutagenic Activities of Organic Extracts from Airborne Particles in Santiago de Chile

“…Concentrations of PAHs measured in this study were considerably higher than those reported from similar studies in other urban areas of the USA and Europe [17,[19][20][21][22][23][24][25] lates, but might also occur during sampling. Since gas samples were not collected for this study, any underesti mation of 2-and 3-ring PAHs cannot be made, but vola tility is unlikely to significantly affect the measurement of 4 or greater ring PAHs, which are the compounds of great est concern from the point of view of mutagenicity and carcinogenicity [30].…”

Recent Advances In Air Pollution Analysis

“…In most studies, subsequent extraction of PAH has used a Soxhlet, with a variety of solvents including dichloromethane, 297 -298 benzene, 299 and cyclohexane. 300 Golden and Sawicki 301 report improved extraction efficiencies by extraction at room temperature with ultrasonic treatment and addition of glass powder to absorb polar coextractives. The ultrasonic technique is also substantially faster, taking only about 40 min, as against 6 to 8 hr typical for Soxhlet extraction.…”

Organic Compounds in Urban Atmospheres: A Review of Distribution, Collection and Analysis

“…The PAH fraction was then injected on a liquid chromatograph equipped with an ODS Zorbax column and about 20 PAH were identified by UV and fluorescence spectrophotometry. 313 ' 367 Some confirmation by mass spectrometry was also carried out. The samples were derived from New York City, College Park, MD, and the harbor tunnel in Baltimore, MD.…”

“…Ultraviolet spectrometry (UV) has found application in pollution related analyses mainly as a detector for LC and HPLC effluents and as an instrument for characterizing PAH skeletons. 313 Reviews on UV spectrometry have appeared.…”
