Resumo
Remnants of Semideciduous Atlantic Forest surrounded by numerous industries, intense road traffic and agricultural
lands in Southeast Brazil have been affected by trace elements. We implemented a passive biomonitoring
with the three most abundant native tree species (Astronium graveolens, Croton floribundus and Piptadenia
gonoacantha) to answer these questions: 1) which species has the greatest potential to accumulate trace elements?;
2) does the leaf accumulation level of trace elements vary between the edge and interior of the forest
remnants, between dry and wet periods or due to the distance from the industrial area?; 3) which species, among
the most abundant in the forest remnants, would better indicate the spatial variations in trace elements pollution
and which elements would be the most relevant for such spatial discrimination? Leaf samples were collected
during the dry and wet seasons, at the edge and interior of four forest remnants. Trace elements were determined
using inductively coupled plasma mass spectrometry (ICP MS). Few edge effects were evidenced in the leaf
concentrations in all species. Higher concentrations of most trace elements were measured during dry season.
Although C. floribundus showed the most accumulating capacity, A. graveolens was the most appropriate species
to discriminate spatial variations. The forest closer to the industrial area was distinguished from the others by
Mn and Ni from oil burning, but the metal pollution from the industrial area did not interfere on the leaf
concentrations in A. graveolens sampled in the urban and rural forests.
