Qualitative Analysis of Highly Toxic Organic Compounds Emitted from Uncontrolled Combustion Sources Using GC-MS/MS

摘要

Qualitative determination of chemical compounds emitted during different types of uncontrolled burning activities has been described.In the investigations several sampling methods were applied.Main analysis was performed using a gas chromatograph connected to a mass spectrometer and a high-performance liquid chromatograph with UV and FL detection systems.The highest emission of chemical substances was measured during household waste combustion.In the collected air samples considerable amounts of volatile organic compounds including toluene,styrene,benzene derivatives,xylene and phtalates isomers,and carbonyl compounds with superiority of formaldehyde,acetone,acrolein,and benzaldehyde were found.In almost each sample 15 polycyclic aromatic compounds were identified.In air samples obtained during combustion of household waste,only hexa-,hepta-,and octa-isomers of dioxins and furans congeners were identified,while in air samples collected during grass or wood combustion any of these congeners was found.
