Legacy and emerging pollutants in marine bivalves from the Galician coast (NW Spain)
(Elsevier, 2019-05-28)The presence of pollutants in estuary and oceanic systems is a global problem and a serious concern to human and environmental health. Usually, environmental monitoring studies consider classical persistent organic pollutants ... -
Linking chemical exposure to lipid homeostasis: A municipal waste water treatment plant influent is obesogenic for zebrafish larvae
(Elsevier, 2019-07-06)Obesity, a risk factor for the development of type-2 diabetes, hypertension, cardiovascular disease, hepatic steatosis and some cancers, has been ranked in the top 10 health risk in the world by the World Health Organization. ... -
Long-term exposure to virgin and seawater exposed microplastic enriched-diet causes liver oxidative stress and inflammation in gilthead seabream Sparus aurata, Linnaeus 1758
(Elsevier, 2021)Plastics accumulation in marine ecosystems has notable ecological implications due to their long persistence, potential ecotoxicity, and ability to adsorb other pollutants or act as vectors of pathogens. The present work ... -
Matrix solid-phase dispersion followed by liquid chromatographytandem mass spectrometry for the determination of selectiveciclooxygenase-2 inhibitors in sewage sludge samples
(Elsevier, 2016-07-20)A straightforward single-step extraction method based on matrix solid-phase dispersion (MSPD), followed by high-performance liquid chromatography with hybrid quadrupole time of flight mass spectrometry (LC–QTOF-MS), was ... -
Modeling Dispersal of UV Filters in Estuaries
(American Chemical Society, 2019-01-11)Lagrangian ocean analysis, where virtual parcels of water are tracked through hydrodynamic fields, provides an increasingly popular framework to predict the dispersal of water parcels carrying particles and chemicals. We ... -
Multi-residue determination of psychoactive pharmaceuticals, illicit drugs and related metabolites in wastewater by Ultra-High Performance Liquid Chromatography-Tandem Mass Spectrometry
(Elsevier, 2018-07-30)This study presents a new multi-residue analytical method for the simultaneous determination of 38 psychoactive drugs (including benzodiazepines, antidepressants and drugs of abuse) and related metabolites in raw wastewater. ... -
Multi-year inter-laboratory exercises for the analysis of illicit drugs and metabolites in wastewater: Development of a quality control system
(Elsevier, 2018-03-22)Thirty-seven laboratories from 25 countries present the development of an inter-laboratory testing scheme for the analysis of seven illicit drug residues in standard solutions, tap- and wastewater. Almost 10 000 concentration ... -
Multiresidue procedure to assess the occurrence and dissipation of fungicides and insecticides in vineyard soils from Northwest Spain
(Elsevier, 2020)The presence of fungicide and insecticide residues in wine has been largely investigated. However, few studies have addressed the persistence of these compounds in vineyard soils. In this research, we investigate the ... -
Nanomaterial Synthesis in Ionic Liquids and Their Use on the Photocatalytic Degradation of Emerging Pollutants
(MDPI, 2021)The unique properties of ionic liquids make them suitable candidates to prepare nanoscale materials. A simple method that uses exclusively a corresponding bulk material and an ionic liquid—in this case, [P6,6,6,14]Cl—was ... -
Occurrence of emerging persistent and mobile organic contaminants in European water samples
(Elsevier, 2019-01-18)The release of persistent and mobile organic chemicals (PMOCs) into the aquatic environment puts the quality of water resources at risk. PMOCs are challenging to analyze in water samples, due to their high polarity. The ... -
Polyethylene microplastics do not increase bioaccumuation or toxicity of nonylphenol and 4-MBC to marine zooplankton
(Elsevier, 2019-07-08)Global production of synthetic polymers, led by polyethylene (PE), rose steadily in the last decades, and marine ecosystems are considered as a global sink. Although PE is not biodegradable, in coastal areas it fragments ... -
Portable dehumidifiers condensed water: A novel matrix for the screening of semi-volatile compounds in indoor air
(Elsevier, 2020)The comprehensive identification of organic species existing in indoor environments is a key issue to understand their impact in human health. This study proposes the analysis of condensed water samples, collected with ... -
Profiling cocaine residues and pyrolytic products in wastewater by mixed‐mode liquid chromatography–tandem mass spectrometry
(Wiley, 2019-03-19)This work provides a new analytical method for the determination of cocaine, its metabolites benzoylecgonine and cocaethylene, the pyrolytic products anhydroecgonine and anhydroecgonine methyl ester, and the pharmaceutical ... -
Proteomic analysis and biochemical alterations in marine mussel gills after exposure to the organophosphate flame retardant TDCPP
(Elsevier, 2021)Organophosphate flame retardants (OPFRs) are (re-)emergent environmental pollutants increasingly being used because of the restriction of other flame retardants. The chlorinated OPFR, tris(1,3-dichloro-2-propyl) phosphate ... -
Reaction of diazepam and related benzodiazepines with chlorine. Kinetics, transformation products and in-silico toxicological assessment
(Elsevier, 2017-05-03)In this work, the reaction of four benzodiazepines (diazepam, oxazepam, nordazepam and temazepam) during water chlorination was studied by means of liquid chromatography-quadrupole-time of flight-mass spectrometry (LC-QTOF-MS). ... -
Reaction of phenazone-type drugs and metabolites with chlorine and monochloramine
(Elsevier, 2020)This work studies the chlorination and monochloramination reaction kinetics of two phenazone-type drugs (phenazone – Phe and propyphenazone – PrPhe) and three metabolites of phenazone-type drugs (4-formylaminoantipyrine – ... -
