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

Estévez Danta, Andrea; Rodil Rodríguez, María del Rosario; Pérez Castaño, Brenda; Cela Torrijos, Rafael; Quintana Álvarez, José Benito; González Mariño, Iria (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 ...

Transformation products of the high-volume production chemicals 1-vinyl-2-pyrrolidinone and 2-piperazin-1-ylethanamine formed by UV photolysis

Sieira Novoa, Benigno José; Rodil Rodríguez, María del Rosario; Cela Torrijos, Rafael; Quintana Álvarez, José Benito; Montes Goyanes, Rosa María (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

Estévez Danta, Andrea; Montes Goyanes, Rosa María; Bijlsma, Lubertus; Cela Torrijos, Rafael; Celma, Alberto; González Mariño, Iria; Miró, Manuel; Gutmann, Vanessa; Pérez de San Román-Landa, Unai; Prieto, Ailette; Ventura, Mireia; Rodil Rodríguez, María del Rosario; Quintana Álvarez, José Benito (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

Castro Bustelo, Verónica; Quintana Álvarez, José Benito; Carpinteiro Botana, Inmaculada; Cobas, Julio; Carro Mariño, Nieves; Cela Torrijos, Rafael; Rodil Rodríguez, María del Rosario (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), ...
