Short summary
We quantified the influence of changes in land use and population density between each catchment area on the fate of atmospheric nitrate, by determining the areal distribution and seasonal variation in stable isotopic compositions of nitrate for more than 30 streams within a same watershed. We found that the absolute concentrations of atmospheric nitrate were almost the same between the streams irrespective to the changes in land use and population density.
