PRESENCE OF ANTI-INFLAMMATORY DRUGS IN SURFACE WATERS OF TAPACHULA CHIAPAS, MEXICO
This study investigated the presence of three non-steroidal anti-inflammatory drugs (NSAIDs: naproxen [NPX], ketoprofen [KFN] and ibuprofen [IBF]), in surface water bodies receiving mostly untreated sewage from the city of Tapachula (South Mexico). Samples were taken during three sampling campaigns from two rivers (Coatán and Texcuyuapan), one urban stream (Coatancito), and one coastal lagoon (Barra San Simón), and the samples were analyzed by gas chromatography-mass spectrometry. Results showed high concentrations of NPX (17.83-142.50 μg L-1), KFN (5.30-67.87 μg L-1) and IBF (3.97-31.30 μg L-1), present in most samples. Correlation analysis between target compounds and physicochemical parameters supported the view that sewage discharge is the main source of these pollutants. Furthermore, estimated hazard indexes suggested a potential threat to aquatic organisms (algae, daphnids and fish) due to high concentrations of NPX and IBF in surface water.Key Words: Developing community, Emerging contaminants, Hazard index, Developing countries.
