Enantiomeric proﬁling of chiral illicit drugs in a pan-European study
The aim of this paper is to present the first study on spatial and temporal variation in the enantiomeric profile of chiral drugs in eight European cities. Wastewater-based epidemiology (WBE) and enantioselective analysis ...
Investigation of pharmaceuticals in processed animal by-products by liquid chromatography coupled to high-resolution mass spectrometry
There is an on-going trend for developing more sustainable salmon feed in which traditionally applied marine feed ingredients are replaced with alternatives. Processed animal products (PAPs) have been re-authorized as novel ...
Comparison of phosphodiesterase type V inhibitors use in eight European cities through analysis of urban wastewater
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 ...
Analytical methodologies based on LC–MS/MS for monitoring selected emerging compounds in liquid and solid phases of the sewage sludge
In this work, two analytical methodologies based on liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) were developed for quantification of emerging pollutants identified in sewage sludge after a previous ...
Identification and characterization of a putative new psychoactive substance, 2-(2-(4-chlorophenyl)acetamido)- 3-methylbutanamide, in Spain
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 ...
Updating the list of known opioids through identification and characterization of the new opioid derivative 3,4-dichloro-N- (2-(diethylamino)cyclohexyl)-N- methylbenzamide (U-49900)
(Springer Nature, 2017)
New psychoactive substances have been rapidly growing in popularity in the drug market as non-illegal drugs. In the last few years, an increment has been reported on the use of synthetic alternatives to heroin, the synthetic ...
Inhibition of larval growth and adult fecundity in Asian long-horned beetle (Anoplophora glabripennis) exposed to azadirachtins under quarantine laboratory conditions
BACKGROUND: The Asian long-horned beetle [ALB; Anoplophora glabripennis (Motschulsky)] is an invasive, wood-boringinsect posing signiﬁcant economic and ecological threats to the deciduous forests of North America. An ...
Reporting the novel synthetic cathinone 5-PPDI through its analytical characterization by mass spectrometry and nuclear magnetic resonance
Introduction: User surveys indicate that expectations of higher drug purity are a key reason for cryptomarket use. In 2014–2015, Spain’s NGO Energy Control conducted a 1-year pilot project to ...
Mass spectrometric strategies for the investigation of biomarkers of illicit drug use in wastewater
The analysis of illicit drugs in urban wastewater is the basis of wastewater‐based epidemiology (WBE), and has received much scientific attention because the concentrations measured can be used as a new non‐intrusive tool ...
Development and validation of ultra high performance-liquid chromatography–tandem mass spectrometry based methods for the determination of neonicotinoid insecticides in honey
In this study, the feasibility of two sample treatments has been evaluated for the determination of seven neonicotinoid insecticides in honey from different botanical origins using ultra-high performance liquid chromatography ...
