Carcinogenic polycyclic organic substances in the fine particles – determination method
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2016, Vol 32, Issue 3
Abstract
Issues associated with the emission of chemical substances from diesel exhaust are still the subject of many studies that lead to, among others, the reduction of pollution and determination of their chemical composition. The International Agency for Research on Cancer (IARC) reclassified exhaust particles from diesel engines from group 2A (probably carcinogenic mixture) to group 1 (carcinogen for humans). According to GUS data from 2010, 480 thousand people were employed in the transport industry, while the number of people exposed to the diesel exhaust was a total of 20719.The aim of this paper was to develop a method for determining carcinogenic polycyclic organic substances occurring in the fraction of fine particles emitted into the environment during the operation of vehicles with diesel engines.Sioutas personal cascade impactor (SPCI) and a 13-tier low-pressure cascade impactor ELPI were used to collect the fraction of particles emitted into the environment. The best results are obtained when using teflon and aluminum filters for samples. The analysis of carcinogens including polycyclic aromatic hydrocarbons adsorbed on particular matter was performed with high-performance liquid chromatography with fluorescence detection in reverse phase.Application of high performance liquid chromatography with fluorescence detection HPLC/FL makes it possible to determine 9 carcinogenic hydrocarbons in the concentration range of 0.0025–1.00 mg·l-1. The correlation coefficient of the calibration curve was 0.99.The procedure for determining PAH present on fractions of particles emitted from engine exhaust gases with a commercial probe SPCI was developed on the basis of the results.
