Resumen:
Abstract: Pharmaceuticals have been included among emerging pollutants due
to their continuous input in aquatic environments by wastewater discharges.
The aim of the present study was detecting and analysing concentration levels
of five commonly used pharmaceuticals in surface water bodies of the Pampas
Region of Argentina. Analyses were done on the soluble fraction by Liquid
Chromatography with Mass Spectrometry (HPLC-MS) after Solid-Phase
Extraction (SPE) extraction. Results show the presence of pharmaceuticals in
10 out of 11 sampling sites, detecting higher concentrations in sites closer to
wastewater discharges. Compounds more commonly found and at higher
concentrations were caffeine and ibuprofen, with maximum detected levels of
13.32 and 9.66 ìg/L, respectively. Highest detected concentrations of
carbamazepine and atenolol were 0.63 and 0.55 ìg/L, respectively. The
compound less frequently detected and at lower levels of concentration was
diclofenac.
