| Zusammenfassung |
| The annual behavior of the concentration of components of atmospheric particulate organic
matter sampled in the atmospheric layer from 500 to 8500 m is discussed. Compounds
ranging from C8H18 to C35H72 were detected in the composition of aerosol particles. The
identified part of organic aerosols showed a distinct seasonal pattern with a maximum in
spring and a minimum during autumn.
The range of hydrocarbons is the widest during the winter period (C12H26–C35H72)
and during spring (C8H18–C31H64), and it is markedly narrower during summer
(C18H38–C33H68) and during autumn (C16H34–C31H64). One mode (n-alkane C20H42)
predominates in aerosol composition throughout the year. A secondary maximum,
corresponding to n-alkane C29H60, appears during the summer period and, possibly, caused
by forest fires
