SPME and SPMD applicability for measurements of terpens and other volatile biomarkers emitted by conifers

Popis výsledku v původním jazyce

Several studies concerned with the influence of atmospheric pollutants and other stress factors (such as ozone) on the conifers have documented an increased emission of (mono)terpens and some other volatile compounds into ambient air by needles. Concentrations of these biomarkers are closely related to the extent of damage of needles cuticular surface layers which represent a natural barrier against unfavorable conditions. In our study alternative sampling techniques including solid phase microextraction (SPME) and semipermeable membrane sampling device (SPMD) were investigated with the aim to recognize their applicability for the assessment of air pollution in localities involved in national monitoring program (atmospheric POPs are here regularly measured by classic large volume samplers as well as by passive samplers represented by local vegetation). Performance characteristics of both techniques obtained within validation protocol (GC/MS/MS used for identification /quantitation of a
