In this work, a multi-class method for the simultaneous determination of 17 emerging contaminants, including pharmaceuticals and personal care products, has been developed.Target analytes were two anti-inflammatories, a lipid regulator agent, two angiotensin II antagonists, two antiepileptic drugs and a diuretic. Among personal care products, four preservatives and five UV filters were included. The method is based on solid-phase extraction (SPE) using Oasis HLB cartridges followed by ultra-high performance liquid chromatographytandem mass spectrometry (UHPLC-MS/MS). Up to three simultaneous transitions per compound were acquired to assure a reliable identification. A detailed study of the extraction process efficiency and matrix effects was carried out in surface water and effluent wastewater.The use of isotope-labeled internal standards (ILIS) was tested to compensate both potential SPE losses during sample extraction and signal suppression/enhancement observed, especially in EWW. Satisfactory correction in all water samples was only ensured when the own analyte ILIS was used. The use of analogues ILIS was a rather useful approach for correction in the majority of the samples tested when analyte ILIS was unavailable. The method was successfully validated in five different surface water (SW) samples and five effluent wastewater (EWW) samples spiked at two concentration levels (0.05 and 0.5 μg/L in SW; 0.1 and 0.5 μg/L in EWW). The developed method was applied to the analysis of 22 samples (SW and EWW) from the Spanish Mediterranean area and 51 reservoir water samples from Colombia. Personal care products were frequently detected, with the highest concentrations corresponding to benzophenone and benzophenone-4 (samples from Spain), and methylparaben (samples from Colombia). Several pharmaceuticals were detected in the Spanish samples, where irbesartan 3 and valsartan -two Angiotensin II antagonists that are not commonly monitored in the aquatic environment -were the compounds most frequently detected.

In this work were determined triclosan and 4n‐nonylphenol in water from a reservoir that is used to provide water to a purification plant in an important city in Colombia. The analytical methodology was validated using solid‐phase extraction and analysis by gas chromatography‐mass spectrometry (GC‐MS). The analysis by GC‐MS showed good linearity in the range of 0.05–5 μg/L for both compounds. Recoveries from 79 to 109% and standard deviations of 2.5–7.7 for low concentrations and from 3.8 to 9.6 (n = 5) for high concentrations were obtained for both compounds. In Colombia, this is the first time that these compounds have been analysed in water supplying of a drinking water treatment plant. The validated method was applied to the analysis of 27 samples collected in August 2010 in 11 locations from the reservoir and in the influent and effluent of the drinking water treatment plant. In total, seven samples were found to contain triclosan.

Los agresores sexuales siempre han constituido un grupo de delincuentes especialmente censurados socialmente. La importancia del bien jurídico contra el que atentan unido a la distorsionada imagen que se transmite a la sociedad sobre las características personales de este grupo de individuos hacen especialmente valiosos los estudios empíricos sobre este tema. Los autores del trabajo que presentamos, que pertenecen al Grupo de Estudios Avanzados en Violencia de la Universidad de Barcelona, ponen sobre la mesa reveladores datos sobre la efectividad del tratamiento realizado con estos sujetos, y la notable reducción de su reincidencia que provoca. La modificación de las distorsionadas creencias de los agresores, el aumento de la empatía y la prevención de la recaída, se han mostrado instrumentos eficaces, que hacen posible la recuperación de un alto porcentaje de sujetos que no vuelven a delinquir una vez fuera de prisión.
