Potential of salvinia biloba raddi for removing atrazine and carbendazim from aquatic environments
Abstract: In this exploratory study, naturally occurring Salvinia biloba Raddi specimens were assessed for atrazine and carbendazim polluted water remediation. Experiments were carried out over 21 days in glass vessels containing deionized water artifcially contaminated with 0, 5, 10, and 20 mg L...

Abstract:
In this exploratory study, naturally occurring Salvinia biloba Raddi specimens were assessed for atrazine and carbendazim
polluted water remediation. Experiments were carried out over 21 days in glass vessels containing deionized water artifcially
contaminated with 0, 5, 10, and 20 mg L−1 of atrazine or carbendazim. Atrazine had a pronounced detrimental impact on
S. biloba, as no biomass development was observed in all macrophytes exposed to this herbicide in the entire concentration
range. However, carbendazim-treated plants were able to grow and survive in the polluted medium even when subjected to
the highest concentration of this fungicide (i.e., 20 mg L−1). In addition, increased chlorosis and necrosis were also detected
in plants subjected to carbendazim as a result of the high phytotoxicity caused by atrazine. A maximal removal efciency
of~30% was observed for both pesticides at 5 mg L−1 and decreased with increasing concentrations of the pollutants. The
spectrum of the FTIR-ATR analysis revealed the existence of various functional groups (e.g., amide, carboxyl, hydroxyl,
phosphate, sulfate) on the plants, which could be related to pesticide biosorption. In addition, at the end of the 21-day
assay, seven carbendazim-resistant bacteria could be isolated from the roots of fungicide-treated plants. Therefore, the use
of autochthonous free-foating S. biloba macrophytes for phytoremediation of aquatic environments contaminated with
carbendazim shows great promise. Still, additional research is required to further elucidate the plant-mediated carbendazim
elimination process and the role of the herbicide-resistant bacteria, and seek alternative species capable of mitigating atrazine
contamination. |
