Resumen:
Biomonitoring is quite a practicable technique nowadays used in the
identification of the air quality in great urban centers. This work had as an
objective to evaluate the possible atmospheric pollutants in the main avenues in
the city of Patos-PB, throughout the analysis of tree vegetables used as
bioindicators. The study was conducted with foliar vegetable material of
arboreal species in downtown of Patos-PB. The data were collected in the
intersection between Solon de Lucena and Epit‹cio Pessoa Pedro Firmino
Avenues, using as control parameters values taken in Nupearido Farm in a
lineal strip of 100m. The foliar material, after been dried in stove at 65ŒC and
reduced, in a Wiley mill, to particles with dimensions inferior to 1mm. The
material was sent to the EMBRAPA Semiarid’s Soil Laboratory Semi‹rido in
Petrolina-PE to determine content of the following chemical elements: S, Fe, Zn
and C. The results obtained point to an important influence of fossil fuel burn by
vehicles in the elements content increase, especially S, in the atmosphere of
great urban centers. The species nim and algaroba stood out as accumulators
of S, the main polluent due to fossil fuel burn.
