Identification and characterization of a putative new psychoactive substance, 2-(2-(4-chlorophenyl)acetamido)- 3-methylbutanamide, in Spain
(Wiley, 2017-02-28)
The term ‘new psychoactive substances’ (NPS) refers to
synthetically changed natural compounds or newly designed
compounds intended to elicit a psychotropic response such as
stimulation, hallucination or sedation.
According ...
Contributions of MS metabolomics to gilthead sea bream (Sparus aurata) nutrition. Serum fingerprinting of fish fed low fish meal and fish oil diets
(Elsevier, 2019-01-01)
The aim of this study was to evaluate the impact of fish meal (FM) and fish oil (FO) replacement by plant proteins and oils in the serum metabolome of two-year old gilthead sea bream (Sparus aurata) fed from early life ...
Analytical research of pesticide biomarkers in wastewater with application to study spatial differences in human exposure
(Elsevier, 2022-07-15)
Wastewater-based epidemiology (WBE) relies on the assessment and interpretation of levels of biomarkers in wastewater originating from a well-defined community. It has provided unique information on spatial and temporal ...
Improving wastewater-based epidemiology to estimate cannabis use: focus on the initial aspects of the analytical procedure
(Elsevier, 2017-10-02)
estimating drug use by the general population, based on the quantitative analysis of specific human metabolites of illicit drugs in urban wastewater. Cannabis is the most commonly used illicit drug and of high interest for ...
Prediction of Collision Cross-Section Values for Small Molecules: Application to Pesticide Residue Analysis
(2017)
The use of collision cross-section (CCS) values obtained by ion mobility high-resolution mass spectrometry has added a third dimension (alongside retention time and exact mass) to aid in the identification of compounds. ...
Behaviour of emerging contaminants in sewage sludge after anaerobic digestion
(Elsevier, 2016)
Nowadays, there is an increasing concern over the presence of contaminants in the aquatic environment, where they can be introduced from wastewater after their incomplete removal in the treatment plants. In this work, ...
Methods involved in the treatment of four representative pharmaceuticals in hospital wastewater using sonochemical and biological processes
(Elsevier, 2023)
A primary pollution source by pharmaceuticals is hospital wastewater (HWW). Herein, the methods involved in the action of a biological system (BS, aerobic activated sludge) or a sonochemical
treatment (US, 375 kHz and ...
LC-IMS-HRMS for identification of biomarkers in untargeted metabolomics: The effects of pterostilbene and resveratrol consumption in liver steatosis, animal model
(Elsevier, 2023)
Untargeted metabolomics with the combination of ion mobility separation coupled to high resolution mass spectrometry (IMS-HRMS) was applied to investigate the impact of resveratrol and pterostilbene supplementation on the ...
Spatio‐temporal assessment of illicit drug use at large scale: evidence from 7 years of international wastewater monitoring
(Wiley, 2020-01)
Background and aims:
Wastewater‐based epidemiology is an additional indicator of drug use that is gaining reliability to complement the current established panel of indicators. The aims of this study were to: (i) assess ...
Liquid chromatography-tandem mass spectrometry determination of synthetic cathinones and phenethylamines in influent wastewater of eight European cities
(Elsevier, 2017)
The popularity of new psychoactive substances (NPS) has grown in recent years, with certain NPS commonly and preferentially consumed even following the introduction of preventative legislation. With the objective to improve ...
