Abstract
Atmospheric organic nitrogen (ON) plays a key role in atmospheric chemistry, contributing significantly to N deposition, particle formation and long-distance transport of nitrogenous compounds. This review addresses the most relevant methodological aspects that should be taken into account for the study of the deposit of this fraction. Likewise, it provides information on the important contribution of ON at the global level, both in rainwater and aerosols, and the main sources where it can be formed. Finally, it shows evidence of the influence of ON on the biogeochemical cycles of N and C. The information gathered in this work shows that despite the advances made in recent years, our understanding of the chemical composition and the implications of the organic fraction on health and ecosystems is far from being complete.
