ResumenThis study presents a quantitative estimation of the analysis and fate of several emerging pollutants, some of them endocrine-disrupting compounds, in surface water samples collected at several locations along the Ter River and two of its tributaries. Influent and effluent waters and particulate matter from five sewage treatment plants (STP) that discharge into these rivers were also studied. The target compounds analyzed were: nonylphenol ethoxylates (NPEO), nonylphenol (NP), octylphenol (OP), bisphenol A (BPA), phthalates, alcohol ethoxylates (AEO) and benzothiazoles. Chemical analysis by liquid chromatography–mass spectrometry using an electrospray interface (LC–ESI–MS) revealed the presence of low amounts (between 0.06 and 17.5 μg L−1) of the target compounds NPE1+2O and NP, which were detected in 100% and 84% of the samples respectively. Maximum concentrations occurred in the STPs associated with the municipalities of Vic and Girona. From the fate and behavior data obtained for the various compounds analyzed in the STP influent and effluent, we can conclude that the STPs are effective at removing large amounts (more than 70%) of the compounds studied from the water.
