The strength in numbers: comprehensive characterization of house dust using complementary mass spectrometric techniques
(Springer, 2019-04)
Untargeted analysis of a composite house dust sample has been performed as part of a collaborative effort to evaluate the progress in the field of suspect and nontarget screening and build an extensive database of organic ...
Isotope Dilution LC-ESI-MS/MS and low resolution Selected Reaction Monitoring as a tool for the accurate quantification of urinary testosterone
(Elsevier, 2018-09)
A new analytical method for the quantification of testosterone in human urine samples by isotope dilution mass spectrometry is proposed. A standard solution of 13C2-testosterone is added to the samples at the beginning of ...
Investigation of pesticides and their transformation products in the Júcar River Hydrographical Basin (Spain) by wide-scope high-resolution mass spectrometry screening
(Elsevier, 2019-10)
The Water Framework Directive 2000/60/EC implemented by the European Union established as the main objectives to achieve a “good ecological and chemical status” of the surface water and a “good quantitative and chemical ...
Electrochemical oxidation of dibenzothiophene compounds on BDD electrode in acetonitrile–water medium
(Elsevier, 2019-05-23)
The electrochemical oxidation of dibenzothiophene and two derivatives, namely 4-methyldibenzothiophene and 4,6-dimethyldibenzothiophene, was investigated either separately or as a mixture, on a BDD anode in a miscible ...
Study of cyanotoxin degradation and evaluation of their transformation products in surface waters by LC-QTOF MS
(Elsevier, 2019-08)
In the present work, the degradation of three cyanotoxins from the hepatotoxins group was investigated under laboratory-controlled experiments in water samples. Surface waters spiked with microcystin-LR (MC-LR), nodularin ...
Facilitating high resolution mass spectrometry data processing for screening of environmental water samples: An evaluation of two deconvolution tools
(Elsevier, 2016)
A screening approach was applied to influent and effluent wastewater samples. After injection in a LC-LTQ-Orbitrap, data analysis was performed using two deconvolution tools, MsXelerator (modules MPeaks and MS Compare) and ...
Variación en el patrón de consumo de cannabinoides sintéticos de una paciente a lo largo de 2018
(Sociedad Científica Española de Estudios sobre el Alcohol, el Alcoholismo y las otras Toxicomanías, 2020)
El consumo de cannabinoides sintéticos es un problema creciente. En España, el número de incautaciones e intoxicaciones relacionadas con estas nuevas sustancias psicoactivas (NPS) es menor que en el resto de Europa. No ...
The NORMAN Association and the European Partnership for Chemicals Risk Assessment (PARC): let’s cooperate!
(Springer, 2020-06-20)
The Partnership for Chemicals Risk Assessment (PARC) is currently under development as a joint research and innovation programme to strengthen the scientific basis for chemical risk assessment in the EU. The plan is to ...
Comparison of isotope pattern deconvolution and calibration curve quantification methods for the determination of estrone and 17β-estradiol in human serum
(Elsevier, 2019-04)
A Liquid Chromatography coupled to tandem mass spectrometry (LC–MS/MS) based method have been developed for the determination of the main estrogen compounds –estrone (E1) and 17β-estradiol (E2)– in human serum. Two isotope ...
