Polybrominated diphenyl ethers belong to group of brominated flame retardants. Important property of these substances is their ability to reduce flammability or to prevent ignition of many products of daily use, such us televisions, carpets, mattresses and many others. Polybrominated diphenyl ethers however are characterized by high persistence and lipophility, leading to their accumulation in the environment. In recent years, concerns about the effects of organic halogen compounds on human health, suggesting their inclusion in the list of persistent organic pollutants in 2009. These contaminants are capable of long-range transport and accumulation in the environment. Therefore, the presence of polybrominated diphenyl ethers is systematically observed in the abiotic and biotic components of the environment worldwide. Their presence has been demonstrated in areas that are clearly very distant from sources of contamination. This thesis is focused on the use of gas chromatography to assess the level of contamination of selected components of the environment, especially of soil. For these purposes was used method of gas chromatography with electron capture detection mass spectrometry.
