Description	Results of this study proved a marginal effect of paracetamol and low concentrations (0.1 and 10 ug/l) of diclofenac to dry weight of duckweed (Lemna minor). Increasing environmental loading (0.1, 10 and 100 ug/l) led in plants to a significant increase in content of reactive oxygen and nitrogen species (ROS, RNS) especially under the effect of paracetamol. Opposingly the occurrence of diclofenac (especially 100 ug/l) decreased significantly the oxido-reductase and dehydrogenase activity and increased the peroxidation of lipids (MDA) and even the permeability of membrane (accumulation of Evans Blue dye).
