摘要：

A method for the determination of benzene, toluene, ethylbenzene and xylenes in plant foliage was developed. Using a gas chromatography-quadrupole mass spectrometer in the selected-ion monitoring mode, calibration graphs and detection limits for these hydrocarbons were determined. Pseudotsuga menziesii (Mirb.) Franco needles and Cotoneaster dammeri Schn. "Skogholm" leaves were extracted with dichloromethane; the optimum extraction time was determined to be 6 h. Differences in the amounts of the hydrocarbons absorbed could be measured.
