These compounds were determined by capillary gas chromatography with flame ionization and/or mass spectrometric detection in the selected ion monitoring mode. The recoveries obtained for the whole analytical procedure were 82-91% for <I>n</I>-alkanes, 68-78% for polycyclic aromatic hydrocarbons, 70-75% for <I>n</I>-alkanals and 2-alkanones, 73-76% for <I>n</I>-alkanols and 80-84% for alkanoic acids. This analytical protocol was suitable for the determination of more than 140 compounds on aeolian particles collected on glass-fibre filters.<I><P> Journal of Chromatography, </I>644 (1993) 141-151<P>
