Aquatic Macrophytes in the Remediation of Atrazine in Water: A Study on Herbicide Tolerance and Degradation Using <i>Eichhornia crassipes</i>, <i>Pistia stratiotes</i>, and <i>Salvinia minima</i>.

ABSTRACT: Aquatic macrophytes can be used for herbicide remediation provided they exhibit tolerance to the contaminants. This research assessed the remediation potential of Salvinia minima, Echhornia crassipes, and Pistia stratiotes, some common aquatic macrophytes native to Brazil, and their tolerance to atrazine, an herbicide commonly detected in waterbodies. Plants were cultivated under controlled conditions with five atrazine concentrations (0, 2, 20, 200, and 1000 μg L^-1) for 15 days. S. minima and E. crassipes tolerated atrazine concentrations equal to or less than 20 μg L^-1 and died at 200 and 1000 μg L^-1, indicating the herbicide's potential toxicity and its selectivity against sensitive species.
