“…It should be noted that while this laboratory focused on the application of HPLC to the detection and measurement of PAH, other techniques, such as GC-MS, could also be applied to the extract (13,17,(19)(20)(21)(22). Gaseous emissions from cigarettes, such as HCHO, can also be analyzed by GC and HPLC (23).…”

“…As highly efficient separation tools, GC and HPLC have been used for analysing all kinds of samples containing complex components. 13 While sensitive HPLC methods have been published for the determination of PAHs, 14,15 GC-MS is more commonly used due to greater separation efficiency of complex non-polar analytes. 16 There are numerous standard procedures to determinate PAHs in ambient air using GC-MS, such as the EPA compendium method TO-13A, 17 the Integrated Atmospheric Deposition Network to analyze PCBs, pesticides and PAHs in air and precipitation samples 18 or the California Environmental Protection Agency method to determine PAHs in ambient air 19 among others.…”

This study has tested and optimized different filter media and pre-conditioning methods, extraction methodologies, cleaning techniques and solvents, concentration procedures and GC-MS parameters in order to establish the best methodology to sample and analyze particle-bound PAH collected in low volume samples (1.4 m 3). The procedure developed combines the use of quartz fiber filters preconditioned at 400 C for 48 h with a simple extraction procedure and optimized GC-MS parameters. The average method detection limits ranged from 4 to 15 pg m À3 for the 4-7 ring PAHs, precision (RSD) ranged from 0.3 to 9.7% and accuracy ranged from À6 to 25%. This method was validated with the extraction and analysis of the Standard Reference Material 1649a and was tested successfully on samples collected in outdoor microenvironments proving suitable for determination of particle-bound PAH concentrations without interferences in low volume samples.

São Paulo metropolitan area presents an intense and chaotic process of urbanization and industrialization. Due to this processes, this region has big atmospheric pollution problem. In certain months of the year, this problem gets worse due to the unfavorable dispersion conditions. The pollutants cause undesirable effects to the environment and to the human health. The chemical characterization and the mutagenic activity evaluation of the compounds present on the atmospheric particulate matter (APM) represents an analytical challenge and it is very important for understanding of the correlation among pollutants, health hazards and emission sources.The goal of this work was chemically characterize the polar and moderately polar organic extracts from the APM collected in São Paulo city and to evaluate their mutagenic activity.The APM is a complex mixture of organic and inorganic compounds present in large range of concentration. Due to this complexity, the chemical fractionation of these organic extracts is necessary to isolate classes or individual compounds, to allow their identification and quantification.The results obtained using different analytical techniques demonstrated that the dichlorometane and acetone extracts has several organic compounds belonging to differerit classes, such as, polycyclic aromatic hydrocarbons, quinolines, ketones, pyridines, furanes, aldehydes, amides and amines. Some of these compounds are considered carcinogens and/or mutagens. The dichloromethane extract presented the highest mass yield and its composition is almost exclusively organic. The acetone extract has organic and inorganic species.Mutagenicity tests revealed that the APM from São Paulo city presented a have relatively high mutagenic activity when compared to other urban regions.
