Journal ArticleDOI
Emerging pollutants in sewage, surface and drinking water in Galicia (NW Spain).
Rosario Rodil,José Benito Quintana,José Benito Quintana,E. Concha-Graña,Purificación López-Mahía,Soledad Muniategui-Lorenzo,Darío Prada-Rodríguez +6 more
TL;DR: This study covered a series of emerging pollutants of different classes, including pharmaceuticals, neutral and acidic organophosphorus flame retardant/plasticizers (OPs), triclosan, phenoxy-herbicides, insect repellents and UV filters, which were carried out on wastewater, surface and drinking water on the NW area of Spain during the four seasons of a year period.
Journal ArticleDOI
Multi-residue analytical method for the determination of emerging pollutants in water by solid-phase extraction and liquid chromatography-tandem mass spectrometry.
Rosario Rodil,José Benito Quintana,José Benito Quintana,Purificación López-Mahía,Soledad Muniategui-Lorenzo,Darío Prada-Rodríguez +5 more
TL;DR: The developed method was applied to the determination of target analytes in various samples, including tap, surface and waste water, and among the tested emerging pollutants, 31 were found in wastewater in concentrations reaching up to 10 microgL(-1) in the case of ibuprofen.
Journal ArticleDOI
Multiresidue analysis of acidic and polar organic contaminants in water samples by stir-bar sorptive extraction–liquid desorption–gas chromatography–mass spectrometry
José Benito Quintana,Rosario Rodil,Soledad Muniategui-Lorenzo,Purificación López-Mahía,Darío Prada-Rodríguez +4 more
TL;DR: The feasibility of stir-bar sorptive extraction followed by liquid desorption in combination with large volume injection (LVI)-in port silylation and gas chromatography-mass spectrometry (GC-MS) for the simultaneous determination of a broad range of 46 acidic and polar organic pollutants in water samples has been evaluated.
Journal ArticleDOI
Multiclass Determination of Sunscreen Chemicals in Water Samples by Liquid Chromatography−Tandem Mass Spectrometry
Rosario Rodil,José Benito Quintana,Purificación López-Mahía,Soledad Muniategui-Lorenzo,Darío Prada-Rodríguez +4 more
TL;DR: A novel analytical method based on solid-phase extraction (SPE) and liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) for the determination of UV sunscreen agents in the water environment is presented, where benzophenone-4 (BP-4) was identified as one of the most important in concentration among the UV filters studied, particularly in wastewater.
Journal ArticleDOI
Spatial and temporal distribution of dissolved/dispersed aromatic hydrocarbons in seawater in the area affected by the Prestige oil spill.

TL;DR: In this paper, the results showed that the concentrations of total aromatic hydrocarbons were found at all depths in the samples collected during December 2002 off the Galicia coast, with levels ranging between 0.19 and 28.8μg/L eq.
