Abstract: Soil pollution can have lasting socioeconomic consequences and an impact on the environment. Pollution can seriously affect the ability of soil to carry out some of its essential functions, and it can affect human health by direct contact or by involvement in the food chain. In order to prevent this, it is necessary to get more information about contaminated sites and the pollutants that are found there. Polybrominated diphenyl ethers are one of the new emerging pollutants found in the environment due to using the equipment containing flame retardants and as a result of irresponsible and illegal disposal and treatment of electronic waste. The aim of this study was to examine the impact of e-waste improperly disposed of in landfills and some other non-landfill sites. The method for determining PBDE's in soil has been optimized, using chemometric model developed for optimization of extraction conditions and instrumental analysis of PBDE's. Optimal duration of extraction, the best ratio of solvents used for extraction and instrumental conditions that give the best recovery of extraction were defined. The optimized conditions were applied on soil samples taken from the surface layer of soil from 24 locations (near landfills, ex marshalling yard, dump of secondary raw materials and automotive waste) in Autonomous Province of Vojvodina. Recovery values of PBDE's congeners ranged between 80% and 115%. Total PBDE's concentrations ranged from 4.4 to 729 μg·kg-1 of absolutely dry soil. Highest contribution to total sum have BDE 99, BDE 47 and BDE 209.
