In several countries around the world, Pharmaceutical and Personal Care Products (PPCPs) exist in aquatic environments, a fact that increases the awareness within the scientific community with respect to their possible fate and environment effects. This research presents a preliminary monitoring of use, consumption and presence of PPCPs in wastewater from a treatment plant in a rural area of Pereira (Colombia). Domestic sewage is treated in a septic tank followed by an Up-Flow Anaerobic Filter and its effluent is discharged into the Otún River, upstream of the water intake of the supply system of the city. The compounds monitored in this research included ibuprofen, naproxen, diclofenac, aspirin, ketoprofen, caffeine, galaxolide, tonalide and dihydrojasmonate. An adapted method of multi-residue analysis was used, which is based on solid phase extraction with hydrophilic-lipophilic balance cartridges, and determination by gas chromatography-mass spectrometry. The removal efficiencies demonstrated that the treatment plant could eliminate less than 50% of dihydrojasmonate, diclofenac and galaxolide existing in wastewater; concentration of aspirin, naproxen and tonalide could only be reduced in 15%; and caffeine, ibuprofen and ketoprofen were not removed. Results provided basic information to decide over the necessity of complementary treatments for effluents from systems with the mentioned units.
En muchos países del mundo, los productos farmacéuticos y de cuidado personal (PPCPs) están presentes en el medio acuático, aumentando las preocupaciones entre la comunidad científica respecto a sus posibles destinos y efectos ambientales. Esta investigación presenta un monitoreo preliminar del uso y consumo de PPCPs y su presencia en las aguas residuales de una planta de tratamiento en zona rural de Pereira (Colombia), donde los vertimientos domésticos son tratadas en un sistema tanque séptico-filtro anaerobio y cuyo efluente se vierte en el río Otún antes de la bocatoma del acueducto de la ciudad. Los compuestos monitoreados en esta investigación incluyen ibuprofeno, naproxeno, diclofenaco, aspirina, ketoprofeno, cafeína, galaxolide, tonalida y dihidrojasmonato. Se utilizó un método de análisis multiresiduo adaptado, que se basa en la extracción en fase sólida con cartuchos de balance hydrophiliclipophilic y determinación por cromatografía de gases-espectrometría de masas. La planta de tratamiento pudo eliminar menos del 50% del dihidrojasmonato, diclofenaco y galaxolida del agua residual; las concentraciones de aspirina, naproxeno y tonalida sólo fueron reducidas en un 15%, y la cafeína, ibuporfeno y ketoprofeno no fueron removidos. Estos resultados proporcionan información base para decidir sobre la necesidad de tratamientos complementarios para los efluentes de estos sistemas de tratamiento.
