Reaction of phenazone-type drugs and metabolites with chlorine and monochloramine
(Elsevier, 2020)
This work studies the chlorination and monochloramination reaction kinetics of two phenazone-type drugs (phenazone – Phe and propyphenazone – PrPhe) and three metabolites of phenazone-type drugs (4-formylaminoantipyrine – ...
Determination of 18 organophosphorus flame retardants/plasticizers in mussel samples by matrix solid-phase dispersion combined to liquid chromatography-tandem mass spectrometry
(Elsevier, 2019-10-12)
This study presents the development and validation of a new analytical method based on matrix solid-phase dispersion (MSPD), integrating sample extraction and clean-up in one single step, followed by liquid chromatography-tandem ...
Combination of different chromatographic and sampling modes for high-resolution mass spectrometric screening of organic microcontaminants in water
(Springer Nature, 2021)
This study explores the combination of two sampling strategies (polar organic compounds integrative sampler (POCIS) vs. spot sampling) and four chromatographic retention modes (reversed-phase liquid chromatography (RPLC), ...
Source identification of amphetamine-like stimulants in Spanish wastewater through enantiomeric profiling
(Elsevier, 2021)
Amphetamine (AMP), methamphetamine (MAMP) and 3,4-methylenedioxymethamphetamine (MDMA) occur in wastewater not only as a result of illicit consumption, but also, in some cases, from prescription drug use or by direct drug ...
Assessing population exposure to phthalate plasticizers in thirteen Spanish cities through the analysis of wastewater
(Elsevier, 2020-06-22)
Phthalates are widely used plasticizers that produce endocrine-disrupting disorders. Quantifying exposure is crucial to perform risk assessments and to develop proper health measures. Herein, a wastewater-based epidemiology ...
Transformation products of the high-volume production chemicals 1-vinyl-2-pyrrolidinone and 2-piperazin-1-ylethanamine formed by UV photolysis
(Elsevier, 2021)
This work investigates the reaction of 1-vinyl-2-pyrrolidinone (VP) and 2-piperazin-1-yletanamine (PPE) under UV radiation. Both substances are high-volume production chemicals (production >1000 tons/year) widely used in ...
Source identification of amphetamine-like stimulants in Spanish wastewater through enantiomeric profiling
(Elsevier, 2021)
Amphetamine (AMP), methamphetamine (MAMP) and 3,4-methylenedioxymethamphetamine (MDMA) occur in wastewater not only as a result of illicit consumption, but also, in some cases, from prescription drug use or by direct drug ...
Chlorination and bromination of 1,3-diphenylguanidine and 1,3-di-o-tolylguanidine: Kinetics, transformation products and toxicity assessment
(Elsevier, 2019-11-13)
This works investigates the chlorination and bromination of two rubber and polymer related chemicals, which have emerged as relevant water contaminants, i.e. 1,3-di-o-tolylguanidine (DTG) and 1,3-diphenylguanidine (DPG). ...
Identification and determination of emerging pollutants in sewage sludge driven by UPLC-QTOF-MS data mining
(Elsevier, 2021)
Sludge from sewage treatment plants (STPs) is recognized as a sink of moderate to high lipophilic compounds resistant to biodegradation. Herein, we investigate the presence of emerging pollutants in sewage sludge combining ...
Supercritical fluid chromatography-mass spectrometric determination of chiral fungicides in viticulture-related samples
(Elsevier, 2021)
Supercritical fluid chromatography (SFC), combined with mass spectrometry (MS), was employed for the determination of five chiral fungicides, from two different chemical families (acylalanine and triazol) in wine and ...
