mobile sources) and nitrate levels around study area.

However, when Friedman test was applied, differences found were not statistically significant, suggesting a certain uniformity in the distribution of sources (especially

To assess the variability of nitrate atmospheric deposition fluxes by land use,

sampling sites were grouped according to the prevailing land use as follows:
