摘要: Abstract This biomonitoring study was aimed at providing an overall assessment of nitrogen oxides (NOX) and tropospheric ozone (O3) in the Grenoble area (Isere, France). Two bioindicators, lichens tobacco plants, were used to estimate, respectively, spatial distribution NOX O3. The following methodological approaches adopted: bioaccumulation lichen Physcia adscendens, bioindication as shown by visible injury plants (cv. Bel W3), community level (IAP). Complementary maps, first based on concentrations second leaf injuries, highly comparable with results obtained from physico-chemical analyses. Multivariate analyses (Canonical Correspondance Analysis) determine relationships between levels atmospheric NO2 O3 communities A sensitivity scale attempted for 43 epiphytic species, which it possible define five clusters according their indifference, or resistance
