| Research Abstract |
An analytical method was established to investigate chemical characteristics of aerosol organic nitrogen (ON). By using the method, diethylamine which is a biogenic tracer was detected in marine aerosol and was found to be more abundant in the sub-μm range of the aerosols in the western North Pacific. The result shows that organic aerosols over the region in summer are enriched in ON that is linked to oceanic biological activity and indicates a preferential transfer of nitrogen-containing organic compounds (mostly water-insoluble) from the sea surface to the marine atmosphere.
