ABSTRACT
Anthropogenic activities contaminate the soils of millions of hectares worldwide with toxic
elements. Native species, such as the Amazonian species Stryphnodendron pulcherrimum, can mitigate
the effects of these elements in soil and have motivated research on phytoremediation. The study’s
objective was to analyze the levels of inorganic components present in rhizosphere soil, roots, and leaves
of S. pulcherrimum in two urban areas in the metropolitan region of Manaus, Brazil. Eight samples
of soil, leaves, and roots of S. pulcherrimum were collected in different areas, totaling 48 samples,
using X-rays by total reflection to quantify trace elements present. Graphical dispersion was performed
using the Principal Component Analysis Method (PCA). The anthropic area provided the predominance
of elements such as Y, Sc, Nb, and Hf, and the forest fragment showed high concentrations of Cu, Yb,
and Ba. Our results indicate that S. pulcherrimum is a species with the potential for phytoremediation in
areas with the presence of heavy metals in soil. The species in the forest fragment presented high leaf
concentrations of Cr, Y, and Yb, suggesting that it may be used for biomonitoring soils. This is the first
report of this species as a bioaccumulator of heavy metals.
