Assessment of Spatial and Temporal Nitrate Dynamics in a Medium‐Sized Watershed Using SWAT‐RIVE
Hydrological Processes, Volume 39, Issue 12, December 2025.Nitrate dynamics in a catchment with multiple anthropogenic pressures were evaluated with SWAT‐RIVE. The results show that 54% of soil nitrate is removed by denitrification, mainly in agricultural areas and wetlands, 8.5% of nitrate inputs to soils reach the river system, and 1.7% is removed by in‐stream processes.

Journal of Separation Science, Volume 48, Issue 9, September 2025.ABSTRACT Spirulina is considered a superfood due to its chlorophylls. Two new methods for the determination of chlorophylls and β‐carotene were developed here, one based on in‐tube solid‐phase microextraction (IT‐SPME) coupled online to nanoliquid chromatography (nanoLC) with diode array detection (DAD), and the other on ultraviolet‐visible diffuse ...
