Anthocyanin derivatives and tannins of red wine by HPLC-DAD-MS/MS. Evolution along winemaking and comparision between Rioja and Bordeaux wines.
(2018-09-14)
Anthocyanins and flavanols play an important role in the quality of wine contributing to sensory aspects such as colour, astringency or bitterness and they can also help in the differentiation between grape varieties and ...
Development of new applications of inductively coupled plasma mass spectrometry (ICP-MS) hyphenated with different sample introduction systems
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2014-05-12)
Hoy en día, la espectrometría de masas con plasma de acoplamiento inductivo (ICP-MS) es una de las técnicas más potentes y versátiles para el análisis de elementos traza dada su robustez y bajos límites de detección. En ...

(2016-07-05)
El objetivo principal de la tesis fue el desarrollo de diferentes metodologías basadas en la microextracción líquido-líquido dispersiva acoplada a diferente instrumentación para la determinación de diversos analitos que ...
Analytical method development for the uptake study of different organic pollutants by crops cultivated in compost-amended soils
(2015-12-11)
Two unavoidable residues from wastewater treatment plants (WWTPs) are effluent water and sewage sludge. The latter, isconsidered one of the largest pollutant sink because it contains a broad range of microorganisms and ...
Analytical method development for the occurrence, distribution and transformation assessment of fluorinated compounds in biota and packaging materials.
(2017-12-01)
Azken urteotan, konposatu fluoratuenganako kezka handituz joan da gizartearen eta zientzialarien artean. Izan ere, kutsatzaile hauek gure eguneroko bizitzan erabiltzen diren material eta tresna ugaritan aurki ditzakegu ...
Metodo analitikoen garapena disruptore endokrinoen biokontzentrazioa arrainetan determinatzeko
(2016-07-22)
Ezaguna da ingurumeneko uretan konposatu endokrinoak (EDC) aurkitzen direla nahiz eta oso kontzentrazio baxuetan (ng/L mailan) egon. Araztegien (WWTP) irteera korronteak izan ohi dira konposatu hauen iturririk nagusienetako ...
Integrated assessment of the presence of emerging compounds and their toxicological effects in estuaries of Biscay
(2018-12-14)
The concern about the widespread presence of ECs in the marine environment and their possible toxic effects is gaining attention. In this PhD we get a close insight about the impact of ECs in estuarine waters and the ...
From effect-directed anaysis to metabolomic assessment: How do the main emerging contaminants released into the Adour estuary affect glass eels (Anguilla anguilla)?
(2022-10-24)
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 high-resolution ...
