Application of liquid chromatography/mass spectrometry in assessment of potential use of azadirachtins (TreeAzin ™ ) against Asian longhorned beetle
(Royal Society of Chemistry, 2014-08)
Azadirachtins are natural triterpenoid compounds derived from Neem tree extracts with potential for use as systemic insecticides against invasive wood-boring insect pests. In this work, a sensitive and selective analytical ...
Wide-scope screening of pharmaceuticals, illicit drugs and their metabolites in the Amazon River
(IWA PublishingElsevier, 2021-05-17)
Only a limited number of households in the Amazon are served by sewage collection or treatment facili- ties, suggesting that there might be a significant emission of pharmaceuticals and other wastewater contaminants into ...
Pesticide Inhalation Exposure of Applicators and Bystanders Using Conventional and Innovative Cropping Systems in the Valencian Region, Spain
(MDPI, 2021-05-15)
This paper provides scientific results from a European LIFE project carried out in the Valencian region of Spain during the 2017 to 2018 time frame. In 2018, more than 60,000 tons of pesticides were commercialized in Spain, ...
Direct and Fast Screening of New Psychoactive Substances Using Medical Swabs and Atmospheric Solids Analysis Probe Triple Quadrupole with Data-Dependent Acquisition
(American Chemical Society, 2020-05-28)
New psychoactive substances (NPS) have become a serious public health problem, as they are continuously changing their structures and modifying their potency and effects on humans, and therefore, novel compounds are ...
Ultra-Performance Liquid Chromatography-Ion Mobility Separation-Quadruple Time-of-Flight MS (UHPLC-IMS-QTOF MS) Metabolomics for Short-Term Biomarker Discovery of Orange Intake: A Randomized, Controlled Crossover Study
(MDPI, 2020)
A major problem with dietary assessments is their subjective nature. Untargeted
metabolomics and new technologies can shed light on this issue and provide a more complete
picture of dietary intake by measuring the profile ...
Multi-year interlaboratory exercises for the analysis of illicit drugs and metabolites in wastewater: development of a quality control system
(Elsevier, 2018)
This study presents the development of a worldwide inter-laboratory testing scheme for the analysis of seven illicit drug residues in different matrices (standard solutions, tap- and wastewater). By repeating this exercise ...
Enhancing spectral quality in complex environmental matrices: Supporting suspect and non-target screening in zebra mussels with ion mobility
(Elsevier, 2022-10-14)
Identification of bioaccumulating contaminants of emerging concern (CECs) via suspect and non-target screening remains a challenging task. In this study, ion mobility separation with high-resolution mass spectrometry ...
Determination of patulin in apple and derived products by UHPLC-MS/MS. Study of matrix effects with atmospheric pressure ionisation sources.
(Elsevier, 2014)
Sensitive and reliable analytical methodology has been developed for the measurement of patulin in regulated foodstuffs by using ultra-high-performance liquid chromatography coupled to tandem mass spectrometry (UHPLC–MS/MS) ...
The relevant role of ion mobility separation in LC-HRMS based screening strategies for contaminants of emerging concern in the aquatic environment
(Elsevier, 2021-05-05)
Ion mobility separation (IMS) coupled to high resolution mass spectrometry (IMS-HRMS) is a promising technique for (non-)target/suspect analysis of micropollutants in complex matrices. IMS separates ionized compounds based ...
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 ...
