[Research advances in stable nitrogen isotope in water bodies.]

Ying yong sheng tai xue bao = The journal of applied ecology, 2018
Water bodies' nitrogen contamination has become more and more serious due to the effects of the intensive development of industry and agriculture. It is important to use nitrogen stable isotope data to identify the nitrogen pollution sources and study the nitrogen cycle of water bodies.

Stable nitrogen isotopic composition of wine: a preliminary investigation

2013
The 15N/14N ratio has been measured in several foods to trace geographical origin and agricultural systems, but not yet in wine. In this work we developed a method for measuring 15N/14N in bulk wine, following dealcoholisation and dehydration. The δ15N of wine did not change after freeze-drying the sample or evaporating it under vacuum, obtaining ...
