TL;DR: Detailed isotopic characterization of 27 commercial fertilizers used in Spain is presented and multi-isotopic analyses, using heavy isotopes, allow us to see beyond the fractionation effects to the fertilizer stable isotope signatures and a better distinction from other anthropogenic contaminants.

TL;DR: In this paper, a comprehensive chemical characterisation of 27 fertilisers of different types used in Spain has been conducted; major, minor and trace elements were determined, including rare earth elements.

TL;DR: Results indicate that intense fertilizer application, causing high nitrate pollution in aquifers, also homogenize the contents of the major dissolved ions, which raises awareness that these processes should be evaluated in advance in order to assess an adequate groundwater resources management.

TL;DR: Anaerobic batch and flow-through experiments were performed to confirm the role of pyrite as electron donor in bacterial denitrification and to look into the feasibility of Pyrite-driven denitification of nitrate-contaminated groundwater.

TL;DR: Vitoria et al. as discussed by the authors described an integrated application of classical hydrogeological methods and multi-isotopic methods to assess the fate of groundwater nitrate in the Osona area, declared vulnerable to nitrate pollution by the Catalan Government in 1998, where nitrate is derived from intensive pig farming activities.
