Nitrogen is a requisite and highly demanded element for living organisms on Earth.
However, increasing human activities have greatly altered the global nitrogen cycle …

Over the past decades, groundwater quality has deteriorated worldwide by nitrate pollution
due to the intensive use of fertilizers in agriculture, release of untreated urban sewage and …

The identification of nitrate (NO 3−) sources and biogeochemical transformations is critical
for understanding the different nitrogen (N) pathways, and thus, for controlling diffuse …
