| 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.
