ABSTRACT
Polycyclic aromatic hydrocarbons are among carcinogenic micro pollutants, which are resistant in the environment. Due to their lipophilic nature and high stability, they accumulate in living organisms and in all parts of the environment. This study focuses on the preparation methods of dust particles for the size fraction below 0.063 mm over the 0,063 mm from the burning slag heap Ema, (the Czech Republic), to determine the concentration of selected PAHs by HPLC with fluorescence detection. This study deals with the preparatory processes for the determination of selected PAHs by the HPLC method with fluorescence detection. The most important factors of sample preparation include the collection, which is mainly influenced by physical-chemical factors. Samples were collected by a method using a passive barrier between the sampled and the sampling medium. This study also presents a list of extraction procedures used for the determination of PAHs along with the used clean-up and fractionation procedures so as to create the best possible methodology for the determination of PAHs in the studied samples from the burning slag heap Ema.
