In this study, we focused on four metrics related to atmospheric problems in urban areas (nitrogen concentration [% N], isotope ratio of nitrogen [δ15N], index of atmospheric purity [IAP], and richness of hygrophilic life-forms [RHL]).

Furthermore, IAP, initially created to characterize atmospheric pollution or atmospheric purity by means of the lichen flora, is shown to be influenced by other parameters such as environmental and landscape factors.
