Sumario:Based in the capacity to filtrate the atmospheric particulate it was established a classification of 90 vegetable species: shrubs and trees, frequently used in Mendoza (Argentina). The method used atmospheric dust collectors, impregnated in liquid vaseline as adherent surface, which are analyzed by a turbidimeter Hach 2100 P, with digital lectures in nefelometric turbidimeter units (NTU). In the samples these collectors were situated inside and outside of the canopy, at least in a number of 15 repetitions for each position. By difference of averages lectures among outside and inside, is reached the characteristicvalue for the specimen. This difference must be related to the canopy´s width crossed by the air current and to the unitary lecture, to obtain comparable values among different specimens, with variations produced by the characteristics of foliage. Itwas stablishedthe following relation: ILi = [ (Loi -Lci)/ (Efi * Loi )] * 100[m-1 where • ILi=interferometric lecture index of the specie "i" • Loi = outside interferometric lecture (average of externals NTU) • Lci= inside interferometric lecture (average of internals NTU) • Efi= width -expressed in m-of canopy crossed by air current, in horizontal straight line. The ILI index allow to characterize the vegetable species in order to their atmospheric dust captation capacity easing their utilization in green spaces projects and in environmental protection.
