Qualitative validation of a liquid chromatography-quadrupole-time of flight mass spectrometry screening method for organic pollutants in waters
(Elsevier, 2013-02)
A multiclass wide-scope screening of organic contaminants in natural and waste water has been developed and validated for qualitative purposes, i.e. detection and reliable identification of compounds detected in samples ...
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 ...
Identification of new omeprazole metabolites in wastewaters and surface waters
(Elsevier, 2014-01)
Omeprazole is one of the world-wide most consumed pharmaceuticals for treatment of gastric diseases. As opposed to other frequently used pharmaceuticals, omeprazole is scarcely detected in urban wastewaters and environmental ...
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 ...
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 ...
Spatial differences and temporal changes in illicit drug use in Europe quantified by wastewater analysis
(Wiley, 2014-08)
Aims To perform wastewater analyses to assess spatial differences and temporal changes of illicit drug use in a large
European population. Design Analyses of raw wastewater over a 1-week period in 2012 and 2013. Setting ...
Monitoring psychoactive substance use at six European festivals through wastewater and pooled urine analysis
(Elsevier, 2020-07-10)
The consumption of psychoactive substances is considered a growing problem in many communities. Moreover, new psychoactive substances (NPS) designed as (legal) substitutes to traditional illicit drugs are relatively easily ...
Photo-electro-Fenton process applied to the degradation of valsartan: Effect of parameters, identification of degradation routes and mineralization in combination with a biological system
(Elsevier, 2018-12)
In this work, the oxidation of the antihypertensive drug valsartan by the Electro-Fenton (EF) and photo-electro-Fenton (PEF) processes was studied using a Ti/IrO2 doped with SnO2 as anode, and a carbon felt air diffusion ...
Investigation of pesticides and their transformation products in the Júcar River Hydrographical Basin (Spain) by wide-scope high-resolution mass spectrometry screening
(Elsevier, 2019-10)
The Water Framework Directive 2000/60/EC implemented by the European Union established as the main objectives to achieve a “good ecological and chemical status” of the surface water and a “good quantitative and chemical ...
Identification of Aquifer Recharge Sources as the Origin of Emerging Contaminants in Intensive Agricultural Areas. La Plana de Castellón, Spain
(MDPI, 2020)
In urban, industrial, and agricultural areas, a vast array of contaminants may be found because they are introduced into the aquifers by different recharge sources. The emerging contaminants (ECs) correspond to unregulated ...
