We evaluate the isolated and combined effects of glyphosate and its by-product aminomethylphosphonic acid (AMPA) and the potential of the aquatic macrophyte Salvinia molesta to remove these chemicals from contaminated water. Plants were exposed to environmentally relevant concentrations of glyphosate (0, 20, 40, 60, 80 and 100 µg l) or AMPA (0, 10, 20, 30, 40 and 50 µg l) for seven days. Then, based on the effective concentrations of glyphosate found to reduce photosynthetic rates by 10% (EC) and 50% (EC), the plants were exposed to combinations of 0, 16 and 63.
