“…Sources of DON are believed to include: pollen, sea spray, soil dust, deposits from fauna and flora, the scavenging of aerosols as well as reactions in the atmosphere between inorganic gaseous nitrogen species and organic compounds (Prospero et al, 1996;Russell et al, 1998;Cornell et al, 2003;Calderon et al, 2007;Zhang et al, 2008;Violaki et al, 2010). Some studies have identified organic N compounds, so that their sources can be traced.…”

“…The former is produced by the dissolution of ammonia gas (NH 3 ) and the scavenging of NH + 4 aerosol, and the latter by the dissolution of nitric acid gas (HNO 3 ) and the scavenging of NO − 3 aerosol (Russell et al, 1998;Cornell et al, 2003;Tian et al, 2011). The dissolved organic nitrogen (DON) fraction is less well documented due to difficulties in measuring it, but it can be an important fraction of the total dissolved nitrogen (TDN) deposited, and can potentially be biologically available as a source of N (Russell et al, 1998;Neff et al, 2002;Cornell et al, 2003;Cape et al, 2004). The sources of DON are not well understood, but it is known to be ubiquitous in the environment, present in particulate, gaseous and aqueous phases (Cornell et al, 2003;Cape et al, 2004;Özel et al, 2011).…”

Abstract. Dissolved organic nitrogen (DON) contributes significantly to the overall nitrogen budget, but is not routinely measured in precipitation or stream water. In order to investigate the contribution of DON to the deposition and export of N, precipitation, stream and soil water samples were collected from an ombrotrophic peatland and analysed for DON over a 2-year period. In wet-only deposition DON contributed up to 10 % of the total dissolved nitrogen (TDN) and was the most dominant fraction in soil water (99 %) and stream water (75 %). NH + 4 was the most dominate form of N in precipitation, with NO − 3 contributing the least to precipitation, soil water and stream water.Precipitation and stream DON were qualitatively analysed by a two-dimensional gas chromatograph coupled to a nitrogen chemiluminescence detector (GC×GC-NCD) after trapping onto C18 solid phase extraction (SPE) cartridges. Ten unique compounds were detected and five identified as pyrrole, benzonitrile, dodecylamine, N-nitrosodipropylamine and decylamine. Five compounds were present in both precipitation and stream samples: pyrrole, benzonitrile and three unidentified compounds. The SPE-extraction efficiency for DON was very low (11 %), but with improvements DON speciation could become a valuable tool to provide information on its sources and pathways and inform chemical transport models.

“…The reactive nitrogen concentrations in precipitation observed in this study are generally at the upper end of the range of literature values reported for coastal sites globally over the past decade (Keene et al, 2002;Luo et al, 2002;Mace et al, 2003b;Kieber et al, 2005;Calderon et al, 2007;Violaki et al, 2010;Cape et al, 2011;Zamora et al, 2011). However, much higher concentrations have been found in rainwater over coastal areas of China, which were attributed to significant pollution associated with the rapid economic development Zhang et al, 2012).…”

Abstract. We measured total dissolved reactive nitrogen in precipitation samples collected at Uljin, a Korean coastal site upwind of the southern East Sea/Sea of Japan (EJS), selected as a representative study site of atmospheric deposition over the northwestern Pacific margin. NO − 3 was found to be the most abundant nitrogen species, followed by NH + 4 and dissolved organic nitrogen (DON). Air-mass back-trajectory (AMBT) analysis revealed that a significant fraction of the inorganic nitrogen (NO − 3 and NH + 4 ) originated from mainland Asia, whereas the DON was primarily derived from Korea. Using varimax-rotated factor analysis in combination with major ions as tracers, agricultural activities in Korea were identified as the primary sources of DON in these samples. In addition, a positive correlation was found at Uljin between the size of organic fraction in total reactive nitrogen and nitrogen to carbon atomic ratio in organic matter. This correlation has also been observed at other locations worldwide, implying the utilization potential of atmospheric organic nitrogen might increase with its proportion in total nitrogen. Combining wet deposition measurements in this study with literature values for dry deposition observed at a remote island in the EJS, the total atmospheric depositional flux of reactive nitrogen was estimated to be 115 mmol N m −2 yr −1 over the southern EJS. Our study sheds new light on the potentially significant contribution to primary productivity of the northwestern Pacific Ocean by atmospheric deposition of nitrogen, especially the organic fraction.

Atmospheric deposition of reactive nitrogen (N) species from air pollutants is a significant source of exogenous nitrogen in marine ecosystems. Here we use an atmospheric chemical transport model to investigate the supply of soluble organic nitrogen (ON) from anthropogenic sources to the ocean. Comparisons of modeled deposition with observations at coastal and marine locations show good overall agreement for inorganic nitrogen and total soluble nitrogen. However, previous modeling approaches result in significant underestimates of the soluble ON deposition if the model only includes the primary soluble ON and the secondary oxidized ON in gases and aerosols. Our model results suggest that including the secondary reduced ON in aerosols as a source of soluble ON contributes to an improved prediction of the deposition rates (g N m À2 yr À1). The model results show a clear distinction in the vertical distribution of soluble ON in aerosols between different processes from the primary sources and the secondary formation. The model results (excluding the biomass burning and natural emission changes) suggest an increase in soluble ON outflow from atmospheric pollution, in particular from East Asia, to the oceans in the twentieth century. These results highlight the necessity of improving the process-based quantitative understanding of the chemical reactions of inorganic nitrogen species with organics in aerosol and cloud water.
