Original Abstract

Polybrominated diphenyl ethers (PBDEs) represent an important group of flame retardants with properties of persistent organic pollutants (POPs). Various studies have documented the presence of these compounds practically in all environmental comparments, both abiotic and biotic. In this study, PBDE congeners No. BDE- 28, 47, 99, 100, 153, 154, 183 were determined in soil samples collected at fire sites where extinguishing preparations were used. In order to assess the consequences of such event on soil, also samples from other localities were analysed. Three different extraction techniques were used for their isolation from examined matrix: (i) ultrasonic extraction, (ii) microwave extraction and (iii) pressurized solvent extraction. For the final determination the gas chromatography (GC) employing two different capillary columns in parallel with electron capture detectors (u-ECD) was employed. The locality of Brno was identified as the emission hot spot. Only some PBDE congeners were found in contaminated soils at concentrations of 90 – 160 ug.kg-1. The most contaminated site was the urban area of Brno (soil from scrapyard) – 167 ug.kg-1.
