Advancing towards universal screening for organic pollutants in waters
Elsevier (2015)Environmental analytical chemists face the challenge of investigating thousands of potential organic pollutants that may be present in the aquatic environment. High resolution mass spectrometry (HRMS) hyphenated to ... -
Analytical strategy to investigate 3,4-methylenedioxypyrovalerone (MDPV) metabolites in consumers’ urine by high-resolution mass spectrometry
Springer (2016-01)The potential of high-resolution mass spectrometry (HRMS) for the investigation of human in vivo metabolism of 3,4-methylenedioxypyrovalerone (MDPV) using urine collected from a consumer (this is, in non-controlled ... -
Analytical study on ethephon residue determination in water by ion-pairing liquid chromatography/tandem mass spectrometry
Taylor & Francis (2011-11-22)A detailed analytical study on ethephon residue determination in water, making use of ion-pairing liquid chromatography coupled to electrospray tandem mass spectrometry (LC/MS/MS), has been carried out. Ethephon is a plant ... -
Critical evaluation of a simple retention time predictor based on LogKow as a complementary tool in the identification of emerging contaminants in water
Elsevier (2015)There has been great interest in environmental analytical chemistry in developing screening methods based on liquid chromatography–high resolution mass spectrometry (LC–HRMS) for emerging contaminants. Using HRMS, compound ... -
Fast determination of 40 drugs in water using large volume direct injection liquid chromatography–tandem mass spectrometry
Elsevier (2015)This work describes a rapid analytical method based on direct sample injection of water samples for the simultaneous identification/quantification of 40 emerging compounds, including pharmaceuticals and drugs of abuse. The ... -
Fragmentation pathways of drugs of abuse and their metabolites based on QTOF MS/MS and MSE accurate-mass spectra
John Wiley (2011-09)A study of the fragmentation pathways of several classes of drugs of abuse (cannabinoids, ketamine, amphetamine and amphetamine-type stimulants (ATS), cocaine and opiates) and their related substances has been made. The ... -
Identification of mycotoxins by UHPLC–QTOF MS in airborne fungi and fungi isolated from industrial paper and antique documents from the Archive of Bogotá
Elsevier (2016-01)Mold deterioration of historical documents in archives and libraries is a frequent and complex phenomenon that may have important economic and cultural consequences. In addition, exposure to toxic fungal metabolites might ... -
No transfer of the non-regulated mycotoxins, beauvericin and enniatins, from feeds to farmed fish reared on plant-based diets
Elsevier (2020-09-01)Concern about the risk of exposure to emerging plant-derived mycotoxins such as beauvericin and enniatins has been addressed by the European Commission who requested the European Food Safety Authority for a scientific ... -
Occurrence of pharmaceutical metabolites and transformation products in the aquatic environment of the Mediterranean area
Elsevier (2021-02-09)The presence of pharmaceutically active substances (PhACs) in aquatic ecosystems is of great concern dueto their constant occurrence in different water systems and potential negative effects on the quality ofwater and ... -
Optimisation and validation of a specific analytical method for the determination of thiram residues in fruits and vegetables by LC–MS/MS
Elsevier (2012)Thiram is a non-systemic dithiocarbamate fungicide, which is easily degraded during sample preparation since it is affected by pH, matrix components and temperature. In this work, specific methodology for thiram analysis ... -
The Power of Hyphenated Chromatography/Time-of-Flight Mass Spectrometry in Public Health Laboratories
American Chemical Society (2012)Laboratories devoted to the public health field have to face the analysis of a large number of organic contaminants/residues in many different types of samples. Analytical techniques applied in this field are normally focused ...
