Outline of Final Research Achievements

The objective of this research project was to investigate the origin and formation processes of atmospheric organic nitrogen (ON) aerosols based on the analysis of their chemical composition and isotope ratios. We found that ON accounted for at a maximum of ~40% of the total nitrogen aerosols in the forest atmosphere. It was suggested that reaction between biogenic hydrocarbons emitted from the forest vegetation and anthropogenic nitrogen is plausible sources for the majority of the observed ON in summer. Contribution of amino acids to the water-soluble ON (WSON) mass was quantified in the various atmospheric environments. WSON was found to reside in the gas phase more than previously recognized.
