Prioritization based on risk assessment to study the bioconcentration and biotransformation of pharmaceuticals in glass eels (Anguilla anguilla) from the Adour estuary (Basque Country, France)
Álvarez Mora, Iker; Bolliet, Valérie; López Herguedas, Naroa; Castro, Lyen; Anakabe Iturriaga, Eneritz; Monperrus, Mathilde Elisabeth; Etxebarria Loizate, Nestor (Elsevier, 2022-10)The presence of contaminants of emerging concern in the aquatic environment directly impacts water-living organisms and can alter their living functions. These compounds are often metabolized and excreted, but they can ... -
Sample preparation for suspect and non-target screening of xenobiotics in human biofluids by liquid chromatography —High resolution tandem mass spectrometry
Baciero Hernández, Inés; Musatadi Larrucea, Mikel; Olivares Zabalandikoetxea, Maitane; Prieto Sobrino, Ailette; Etxebarria Loizate, Nestor; Zuloaga Zubieta, Olatz (Elsevier, 2023-11-29)The concept of exposome covers all the exposures an individual suffers from conception to death, which can be partially assessed through the monitoring of human biofluids. In there, target ana- lytical approaches tend to ... -
SETApp: A machine learning and image analysis based application to automate the sea urchin embryo test
Álvarez Mora, Iker; Mijangos Treviño, Leire; López Herguedas, Naroa; Amigo Rubio, José Manuel ; Eguiraun Martínez, Harkaitz; Salvoch, Maddi; Monperrus, Mathilde Elisabeth; Etxebarria Loizate, Nestor (Elsevier, 2022-08)[EN] Since countless xenobiotic compounds are being found in the environment, ecotoxicology faces an astounding challenge in identifying toxicants. The combination of high-throughput in vivo/in vitro bioassays with ... -
Suspect Screening of Chemicals in Hospital Wastewaters Using Effect-Directed Analysis Approach as Prioritization Strategy
López Herguedas, Naroa; Mijangos Treviño, Leire; Álvarez Mora, Iker; González Gaya, Belén; Uribe Echeverria, Teresa; Etxebarria Loizate, Nestor; Zuloaga Zubieta, Olatz; Olivares Zabalandicoechea, Maitane; Prieto Sobrino, Ailette (MDPI, 2023-01-26)The increasing number of contaminants in the environment has pushed water monitoring programs to find out the most hazardous known and unknown chemicals in the environment. Sample treatment-simplification methods and ... -
Testing Wastewater Treatment Plant Effluent Effects on Microbial and Detritivore Performance: a Combined Field and Laboratory Experiment
Solagaistua Zabala, Libe; De Guzmán Martínez, Miren Ioar ; Barrado, Miren; Mijangos Treviño, Leire; Etxebarria Loizate, Nestor; García-Baquero Moneo, Gonzalo ; Larrañaga Arrizabalaga, Aitor; Von Schiller Calle, Daniel Gaspar ; Elosegi Irurtia, Arturo (Elsevier, 2018-10)The amount of pollutants and nutrients entering rivers via point sources is increasing along with human population and activity. Although wastewater treatment plants (WWTPs) greatly reduce pollutant loads into the environment, ... -
The role of sample preparation in suspect and non-target screening for exposome analysis using human urine
Musatadi Larrucea, Mikel; Andrés Maguregi, Asier; De Angelis, Francesca; Prieto Sobrino, Ailette; Anakabe Iturriaga, Eneritz; Olivares Zabalandicoechea, Maitane; Etxebarria Loizate, Nestor; Zuloaga Zubieta, Olatz (Elsevier, 2023-10)The use of suspect and non-target screening (SNTS) for the characterization of the chemical exposome employing human biofluids is gaining attention. Among the biofluids, urine is one of the preferred matrices since organic ... -
Toxicity to sea urchin embryos of crude and bunker oils weathered under ice alone and mixed with dispersant
De Miguel Jiménez, Laura ; Etxebarria Loizate, Nestor; Reinardy, Helena C.; Lecube Iturrioz, Xabier; Marigómez Allende, Juan Antonio ; Izaguirre Aramayona, Urtzi (Elsevier, 2022)[EN] A multi-index approach (larval lenghthening and malformations, developmental disruption, and genotoxicity) was applied using sea-urchin embryos as test-organisms. PAH levels measured in the under-ice weathered aqueous ... -
Water Reuse Study from Urban WWTPs via c-Ultrafiltration and Ozonation Technologies: Basis for Resilient Cities and Agriculture
Ferreiro Santiso, Cristian ; Villota Salazar, Natalia ; De Luis Álvarez, Ana María ; Lombraña Alonso, José Ignacio ; Etxebarria Loizate, Nestor; Lomas Esteban, José María (MDPI, 2021-02-12)The water–development nexus is essential for the advancement and progress of cities in the face of problems such as climate change, water security and increasing environmental stress in the agricultural sector. Aiming for ...
