The phytoremediation potential of Brazilian trees species
Calophyllum brasiliense
,
Eremanthus crotonoides
,
Hymenaea courbaril
,
Inga striata
, and
Protium heptaphyllum
was investigated for contaminated soils containing ametryn and hexazinone. Visual injury, chlorophyll content, plant height, leaf temperature, leaf number, and water-efficient use were evaluated. Residual herbicides at soil substrates were analyzed by LC/MS. Among the species
C. brasiliense
and
H. courbaril
were tolerant to both herbicides.
P. Heptaphyllum
presented tolerance at ametryn treatment.
E. crotonoides
,
I. striata
, and
P. heptaphyllum
died in hexazinone treatment. A high content of residual ametryn was found for
E. crotonoides
. In ametryn treatment, residual herbicide has decreased for
C. brasiliense
and
E. crotonoides
species.
C. brasiliense
highlighted among others becoming a good agent for phytoremediation of soils contaminated with traces of ametryn and hexazinone.
