The aim of this study was to determine the interaction between anionic surfactants and macrophytes. Two different types of surfactants were chosen for the study: SDS (non-aromatic) and LAS (aromatic). Lemna minor was the macrophyte of choice, an aquatic plant, useful for its selective removal of ammonia, its ability to cover the surface of water bodies, and to remove heavy metals from effluents. The experiments with L. minor were performed in the presence and absence of nutrients. The concentrations of surfactants used were similar to those which can be found in wastewater. Under these experimental conditions L. minor was not affected. Because of this, L. minor used in treatment ponds appears not to be affected by the presence of surfactants. Moreover it can diminish their concentration in effluents prior to its disposal in water bodies.
