Abstract: Isotopic compositions (δ15N, δ18O, and Δ17O) of nitrogen dioxide (NO2) are crucial proxies for elucidating the sources and transformations of atmospheric NO2, yet observations remain scarce. Here, we reported high-resolution (2 h interval) measurements of… read more here.

Abstract: ABSTRACT Stable isotope ratios of nitrogen and oxygen (15N/14N and 18O/16O) of nitrate (NO3 –) are excellent tracers for developing systematic understanding of sources, conversions, and deposition of reactive atmospheric nitrogen (Nr) in the environment.… read more here.

Abstract: Nitrate pollution is of considerable global concern as a threat to human health and aquatic ecosystems. Nowadays, δ15N/δ18O-NO3- combined with a Bayesian-based SIAR model are widely used to identify riverine nitrate sources. However, little is… read more here.
