    Drugs are considered within the so-called emerging pollutants, so it is important to investigate the toxic effects they can produce in the environment. The aim of this study was to determine the toxic effect of aqueous solutions of ibuprofen on an aquatic organism Artemia salina and the seeds of Allium schoenoprasum L and Lactuca sativa. The toxicity tests were carried out by exposing the test organisms to concentrations of aqueous ibuprofen solutions of 20, 10, 5, 2, 1 and 0.5 mgL-1. The percentage of mortality for Artemia salina and the elongation of the radicle and hypocotyl for the seeds were determined. The highest mortality percentage occurred at the concentration of 20 mgL-1, the calculated LC50 was 17.386 mgL-1. A low toxic effect was present in the germination of the seeds of Allium schoenoprasum L. There was inhibition in the elongation of the radicle and hypocotyl in seeds of Allium schoenoprasum L and a stimulation effect in the elongation of the radicle and hypocotyl of the seeds of Lactuca sativa. The highest inhibition effect was presented at 1 and 20mgL-1 and the highest stimulation at 20 mgL-1.
