Abstract
A “paraffin” hypothesis of the origin of spring nucleation bursts (NB) is discussed. The organic part of atmospheric aerosol is analyzed using the gas chromatography-mass spectrometry and the chemical structure classification. The results obtained during NB events and in preceding (next) days (when no new particle formation was observed) are compared. A suggestion that new particles are formed from the surface waxes of plants during the NB events is considered.
