Resumo
The main anatomical features of Tibouchina granulosa (Desr.) Cong. (Melastomataceae) have been investigated in order to assess the potential of the species as a possible biomonitor of air pollution in the state
of São Paulo, Brazil. Various types of trichomes located on the adaxial and abaxial surfaces of the leaves
of this ornamental tree were able to adsorb particulate matter (PM) within the size range 2.5–100 m.
Following dry or wet deposition, the particles remained adsorbed to the leaves and did not return to the
environment under normal weather conditions. The numbers of particles adsorbed per unit area of leaf
differed significantly depending on the location at which the samples were collected. Leaves from a relatively unpolluted site located in a remnant of the Atlantic Forest within the city of São Paulo showed the
lowest particle density, while samples collected in the city centers of São Paulo and Cubatão presented
the highest numbers of particles with aerodynamic sizes <2.5 and 2.5–10 m. It is concluded that T. granulosa may be employed as a passive biomonitor, thereby offering a valuable alternative for monitoring
air pollution and spatial–temporal evaluation of PM composition. Additionally, landscape cultivation of
T. granulosa in inner-city areas may help to improve the quality of air by reducing the concentration of
harmful PM2.5 and PM10.
