Risk assessment for drugs of abuse in the Dutch watercycle
(Elsevier, 2013-04)
A screening campaign of drugs of abuse (DOA) and their relevant metabolites in the aqueous environment was performed in the Netherlands. The presence of DOA, together with the potential risks for the environment and the ...
Quality classification of Spanish olive oils by untargeted gas chromatography coupled to hybrid quadrupole–time of flight mass spectrometry with atmospheric pressure chemical ionization and metabolomics-based statistical approach
(Elsevier, 2017-02)
The novel atmospheric pressure chemical ionization (APCI) source has been used in combination with gas chromatography (GC) coupled to hybrid quadrupole time-of-flight (QTOF) mass spectrometry (MS) for determination of ...
LC-QTOF MS screening of more than 1,000 licit and illicit drugs and their metabolites in wastewater and surface waters from the area of Bogotá, Colombia
(Springer, 2015-08)
A large screening of around 1,000 emerging contaminants, focused on licit and illicit drugs and their metabolites, has been made in urban wastewaters (both influent and effluent) and surface waters from the area of Bogotá, ...
Identification of Unknown Substances in Ambient Air (PM10), Profiles and Differences between Rural, Urban and Industrial Areas
(MDPI, 2022-04)
A fast and automated strategy has been developed for identifying unknown substances
in the atmosphere (concretely, in the particulate matter, PM10) using LC-HRMS (MS3). A total
of 15 samples were collected in three ...
Application of gas chromatography–(triple quadrupole) mass spectrometry with atmospheric pressure chemical ionization for the determination of multiclass pesticides in fruits and vegetables
(Elsevier, 2013-11)
A multi-residue method for the determination of 142 pesticide residues in fruits and vegetables has been developed using a new atmospheric pressure chemical ionization (APCI) source for coupling gas chromatography (GC) to ...
The role of GC-MS/MS with triple quadrupole in pesticide residue analysis in food and the environment
(Royal Society of Chemistry, 2013)
Gas chromatography coupled to tandem mass spectrometry (GC-MS/MS) using a triple quadrupole (QqQ) analyzer has in the last few years become a powerful technique for the determination of pesticide residues due to its ...
Application of gas chromatography–(triple quadrupole) mass spectrometry with atmospheric pressure chemical ionization for the determination of multiclass pesticides in fruits and vegetables
(Elsevier, 2013-11)
A multi-residue method for the determination of 142 pesticide residues in fruits and vegetables has been developed using a new atmospheric pressure chemical ionization (APCI) source for coupling gas chromatography (GC) to ...
Gas chromatography-mass spectrometry based untargeted volatolomics for smoked seafood classification
(Elsevier, 2020-11)
With the increase of the demand of low flavouring smoked seafood products, there is a need of methodologies
able to distinguish between different seafood treatments, as not all of them are allowed in all markers.
Following ...
Investigation of cannabis biomarkers and transformation products in waters by liquid chromatography coupled to time of flight and triple quadrupole mass spectrometry
(Elsevier, 2014-03)
11-Nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH) is commonly selected as biomarker for the investigation of cannabis consumption through wastewater analysis. The removal efficiency of THC-COOH in wastewater treatment ...
Occurrence and behavior of illicit drugs and metabolites in sewagewater from the Spanish Mediterranean coast (Valencia region)
(Elsevier, 2014-07)
In this work, a study on the occurrence and behavior of illicit drugs and metabolites in sewage water systems has been made. A comprehensive dataset was obtained by analyzing illicit drugs daily in influent and effluent ...
