Determination of selected xenobiotics in plant bioindicators

Monitoring of environment is basic aspect of detection of environment state. It is practice by analysis of water, air, soil and bioindicators. This thesis is aimed at elected bioindicators of plant origin, needles of pine-tree and spruce, and at determination of chosen xenobiotic, polybrominated diphenyl ethers (PBDE) in this bioindicators. PBDE are used as flame retardants and they are occurred in all components of environment, thanks to their properties and ability of bioaccumulation. In thesis is described separation of substances from sample using different extraction techniques and final gas chromatography. Experimental part is aimed at sample preparation, determination of chosen congeners PBDE and comparison of effectivity of used extraction techniques
