The occurrence of 16 pharmaceutical compounds in river sediments from Donana National Park was investigated, as well as the ecotoxicological risk to the ecosystems of this well-known protected zone. Eight of the 16 pharmaceuticals were present in sediments. The highest concentrations in river sediments concern to diclofenac, salicylic acid and caffeine (52.1, 27.2 and 25.4 mu g/kg dm). Naproxen, carbamazepine, propranolol, 17 beta-estradiol and estriol were the other pharmaceutical compounds detected in sediment samples. The relation between the concentration of these pharmaceutical compounds in sediments and river water in contact with was also investigated. While some compounds were detected exclusively in sediment samples (diclofenac, 17 beta-estradiol and estriol), others were detected only in surface waters in contact with (ibuprofen, ketoprofen and gemfibrozil). The outcome analyses of the ecotoxicological risk assessment showed that the presence of all studied pharmaceutical compounds involved a high toxicological risk at short and long term to Donana ecosystem.
