Development of QuEChERS-based multiresidue analytical methods to determine pest...
García-Vara, Manuel; Postigo, Cristina; López de Alda, Miren; Palma, PatríciaAnalytical methods based on QuEChERS and liquid chromatography-tandem mass spectrometry were developed for the determination of 42 polar and semi-polar pesticides in three representative vegetable matrices, viz. corn, grapes and alfalfa. A 26-2 fractional factorial experimental design was used to cost-effectively optimize the extraction procedure. The optimal analytical approaches were validated in terms of lin...
Spatio‐temporal assessment of illicit drug use at large scale: evidence from 7 ...
González‐Mariño, Iria; Baz‐Lomba, Jose Antonio; Alygizakis, Nikiforos A.; Andrés‐Costa, Maria Jesus; Bade, Richard; Bannwarth, Anne; Barron, Leon P.Background and aims Wastewater‐based epidemiology is an additional indicator of drug use that is gaining reliability to complement the current established panel of indicators. The aims of this study were to: (i) assess spatial and temporal trends of population‐normalized mass loads of benzoylecgonine, amphetamine, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA) in raw wastewater over 7 years (2011–...
Ecotoxicological risk assessment of tributaries to the Alqueva reservoir (South...
Palma, Patrícia; Fialho, Sofia; Lima, Ana; Penha, Alexandra; Novais, Maria Helena; Monllor-Alcaraz, Luis Simon; Guillem-Argiles, NuriaThe Alqueva reservoir constitutes the most important water supply source in Southern Portugal, a Mediterranean region, affected by water scarcity and where agriculture is one of the main activities. The aim of this study was to assess the usefulness of the use of ecotoxicological endpoints to detect chemical alterations in the tributaries to the Alqueva reservoir, that may affect its water quality. Water and se...
Ecotoxicological tools to assess the impact pollution of tributaries to the Alq...
Palma, Patrícia; Fialho, Sofia; Lima, Ana; Penha, Alexandra; Novais, Maria Helena; Monllor-Alcaraz, Luis Simon; Guillem-Argiles, NuriaDegradation of surface waters and biodiversity loss at different spatial and temporal scales occurs through multiple stressors whose effects are difficult to separate and identify. Efficient management of water bodies depends on the development and selection of robust, sensitive and easily applicable tools that allow prioritizing the pressures and stressors that act in a basin, and mitigate their effects. The A...
Comparative measurement and quantitative risk assessment of alcohol consumption...
Ryu, Yeonsuk; Barceló, Damià; Barrone, Leon P.; Bijlsma, Lubertus; Castiglioni, Sara; De Voogt, Pim; Emke, Erik; Hernández, Félix; Lai, Foon YinQuantitative measurement of drug consumption biomarkers in wastewater can provide objective information on community drug use patterns and trends. This study presents the measurement of alcohol consumption in 20 cities across 11 countries through the use of wastewater-based epidemiology (WBE), and reports the application of these data for the risk assessment of alcohol on a population scale using the margin of ...
Transcriptomic, biochemical and individual markers in transplanted Daphnia magn...
Rivetti, Claudia; Campos, Bruno; Faria, Melissa; Català, Nuria De Castro; Malik, Amrita; Muñoz, Isabel; Tauler, Romà; Soares, Amadeu M. V. M.Daphnia magna individuals were transplanted across 12 sites from three Spanish river basins (Llobregat, Ebro, Jucar) showing different sources of pollution. Gene transcription, feeding and biochemical responses in the field were assessed and comparedwith those obtained in re-constitutedwater treatments spikedwith organic eluates obtained fromwater samples collected at the same locations and sampling periods.
