Analytical investigation of cannabis biomarkers in raw urban wastewater to refine consumption estimates
Elsevier (2022-08)Wastewater analysis of Δ9-tetrahydrocannabinol (THC) biomarkers can provide essential information on trends in cannabis consumption. Although analysis is mostly focused on the aqueous phase, previous studies have illustrated ... -
Analytical key issues and challenges in the LC-MS/MS determination of antibiotics in wastewater
(2023-01-25)The research on antibiotics occurrence in the aquatic environment has become a hot topic in the last years due to their potential negative effects, associated to possible bacterial antibiotic-resistance, after continuous ... -
Comparison of phosphodiesterase type V inhibitors use in eight European cities through analysis of urban wastewater
Elsevier (2018-06)In this work a step forward in investigating the use of prescription drugs, namely erectile dysfunction products, at European level was taken by applying the wastewater-based epidemiology approach. 24-h composite samples ... -
Determination of free amino acids in plants by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS)
Royal Society of Chemistry (2015)A robust and sensitive method for identification (quantification and confirmation) of 19 free amino acids in the plant matrix, Stellaria media, based on liquid chromatography-electrospray ionization-tandem mass spectrometry ... -
Estimation of illicit drug use in the main cities of Colombia by means of urban wastewater analysis
Elsevier (2016-09)Wastewater-based epidemiology (WBE) relies on the principle that traces of compounds, which a population is exposed to or consume, are excreted unchanged or as metabolites in urine and/or feces, and ultimately end up in ... -
Evaluation of direct sample injection as a fast, no-sample handling, approach for the LC-MS/MS monitoring of pharmaceuticals in different water matrices
Elsevier (2023)The determination of drug residues in water, particularly in environmental water, is a hot topic due to the usual presence of these emerging contaminants in the aquatic environment and their potential negative impact ... -
LC-MS/MS method for the determination of organophosphorus pesticides and their metabolites in salmon and zebrafish fed with plant-based feed ingredients
Springer (2019)The composition of Atlantic salmon feed has changed considerably over the last two decades from being marine-based (fishmeal and fish oil) to mainly containing plant ingredients. Consequently, concern related to traditional ... -
Mass Spectrometric Evaluation of Mephedrone In Vivo Human Metabolism: Identification of Phase I and Phase II Metabolites, Including a Novel Succinyl Conjugate
American Society for Pharmacology and Experimental Therapeutics (ASPET) (2015-02)In recent years, many new designer drugs have emerged, including the group of cathinone derivatives. One frequently occurring drug is mephedrone; although mephedrone was originally considered as a “legal high” product, it ... -
Multi-residue determination of pesticides in tropical fruits using liquid chromatography/tandem mass spectrometry
Springer (2012-03)Monitoring pesticide residues in tropical fruits is of great interest for many countries, e.g., from South America, that base an important part of their economy on the exportation of these products. In this work, a LC-MS/MS ... -
Rapid and sensitive analytical method for the determination of amoxicillin and related compounds in water meeting the requirements of the European union watch list
Elsevier (2021-10-07)The presence of antibiotics in the aquatic environment is becoming one of the main research focus of scientists and policy makers. Proof of that is the inclusion of four antibiotics, amongst which is amoxicillin, in the ... -
Re-certification of hydroxyvitamin D standards by isotope pattern deconvolution
Elsevier (2019-04-22)Background Vitamin D testing in analytical clinical laboratories has been experiencing a rapid increase of demand over the last years, as it plays a key role in several disorders. Due to the narrow ranges of medical ...
