Comprehensive determination of phthalate, terephthalate and di-iso-nonyl cyclohexane-1,2-dicarboxylate metabolites in wastewater by solid-phase extraction and ultra(high)-performance liquid chromatography-tandem mass spectrometry
(Elsevier, 2021)
Plasticizers are chemical compounds used in the production of flexible plastics for a large variety of applications. They are present in most of the environments and, hence, we are highly exposed to them via several routes ...
Determination of pesticide residues in wine by solid-phase extraction on-line combined with liquid chromatography tandem mass spectrometry
(Elsevier, 2021)
Liquid chromatography tandem mass spectrometry (LC–MS/MS) has been combined with different sample preparation strategies to determine potential pesticide residues existing in wine. Herein, we propose the on-line coupling ...
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 ...
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 ...
Approaches to liquid chromatography tandem mass spectrometry assessment of glyphosate residues in wine
(Springer, 2021)
The performance of two different analytical methodologies to investigate the presence of glyphosate (GLY) and aminomethylphosphonic acid (AMPA) residues in wine samples was evaluated. Transformation of compounds in their ...
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 ...
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), ...
