Emission of polycyclic aromatic hydrocarbons from the exhalation zones of thermally active mine waste dumps

The article presents results of research carried out on the occurrence of polycyclic aromatic hydrocarbons (PAH) in gases of exhalation zones, created on the surface of a thermally active coal mine waste dump. The oxidation and self-heating of mine waste are accompanied with the intensive emission of flue gases, including PAH group compounds. Taking into consideration the fact the hydrocarbons show strong genotoxic, mutagenic and carcinogenic properties, research was conducted to establish their content in the examined gases. The research object was a gangue dump located in Rybnik. The research was performed in 2012. In total, 24 samples of gas were collected with PUF (polyurethane foam) sampling cartridges with a quartz fibre filter and an aspirator. The collected samples were analysed with the use of high performance liquid chromatography (HPLC) and a fluorescence detector (FLD) to evaluate the amount of PAH present.
