Abstract: Plant-based systems for the treatment of contaminated environments (phytoremediation) have been
proved to be highly efficient in removing pollutants, especially heavy metals. However, in strictly
aquatic and high-flow treatment systems, the use of free floating plants could be more adequate. For
a treatment system based on phytoremediation strategies to be feasible and sustainable, it is essential
that the plants used are not only efficient in pollutants removal, but also abundant in the region, easily
accessible, and do not require special culture conditions. In this work, we evaluate the capacity of four
different autochthonous macrophytes obtained from the Paraná river (Argentina) to adapt and reproduce without any additional nutrient supply or temperature special conditions (laboratory «indoor»
environment). Only those specimens that doubled their biomass in a two-week period without any
visual signs of deterioration (loss of turgor, chlorosis and/or necrosis of leaves) were considered for
further analysis. From different pre-selected species, only Salvinia biloba Raddi showed a wide capacity to adapt and reproduce under these conditions. Moreover, the ability to remove lead (Pb2+) by S.
bilobawas evaluated in water samples contaminated with three metal concentrations (4.8 ± 0.3, 9.1 ± 0.4
and 19.6 ± 0.5 mg/L) at different exposure times (0–24 h), showing a high efficiency in the pollutant
elimination. A compartmentalization analysis indicates that surface adsorption was the predominant
mechanism for Pb2+ removal at the first 24 h. Finally, the bioconcentration factor (BCF) was calculated at
the end of the exposure time,reflecting both hyperaccumulation capacity and high metal tolerance by
this plant. Our results suggest that incorporation of S. biloba in wastewater treatment systems could be
a successful strategy to efficiently remove heavy metals by bioremediation processes. |
