Wastewater-based epidemiology as a novel tool to evaluate human exposure to pesticides: Triazines and organophosphates as case studies
(Elsevier ScienceDirect, 2021-06-22)
Production and application of pesticides have risen remarkably in the last few decades. Even if they provide many benefits, they can be hazardous for humans and ecosystems when they are not used cautiously. Human exposure ...
Atmospheric-Pressure Chemical Ionization Tandem Mass Spectrometry (APGC/MS/MS) an Alternative to High-Resolution Mass Spectrometry (HRGC/HRMS) for the Determination of Dioxins
(ACS Publications, 2015-09-01)
The use of a new atmospheric-pressure chemical ionization source for gas chromatography (APGC) coupled with a tandem quadrupole mass spectrometry (MS/MS) system, as an alternative to high-resolution mass spectrometry (HRMS), ...
Analytical study on ethephon residue determination in water by ion-pairing liquid chromatography/tandem mass spectrometry
(Taylor & Francis, 2011-11-22)
A detailed analytical study on ethephon residue determination in water, making use of ion-pairing liquid chromatography coupled to electrospray tandem mass spectrometry (LC/MS/MS), has been carried out. Ethephon is a plant ...
Multiclass determination of 66 organic micropollutants in environmental water samples by fast gas chromatography–mass spectrometry
(Springer, 2012-03)
A multiresidue method has been developed for quantification and identification of 66 multiclass priority organic pollutants in water by fast gas chromatography (GC) coupled to mass spectrometry (MS). Capabilities and ...
Fragmentation pathways of drugs of abuse and their metabolites based on QTOF MS/MS and MSE accurate-mass spectra
(John Wiley, 2011-09)
A study of the fragmentation pathways of several classes of drugs of abuse (cannabinoids, ketamine, amphetamine and amphetamine-type stimulants (ATS), cocaine and opiates) and their related substances has been made. The ...
An Initial Approach to the Presence of Pharmaceuticals in Wastewater from Hospitals in Colombia and Their Environmental Risk
(MDPI, 2022-03-18)
Hospital wastewater (HWW) from three different cities in Colombia was characterized.

Characterization of the organic contamination pattern of a hyper-saline ecosystem by rapid screening using gas chromatography coupled to high-resolution time-of-flight mass spectrometry
(Elsevier, 2012-09)
In this paper, gas chromatography coupled to high-resolution time-of-flight mass spectrometry (GC–TOF MS) has been applied to evaluate organic pollution in a hyper-saline aquatic environment. Firstly, a target screening ...
The Power of Hyphenated Chromatography/Time-of-Flight Mass Spectrometry in Public Health Laboratories
(American Chemical Society, 2012)
Laboratories devoted to the public health field have to face the analysis of a large number of organic
contaminants/residues in many different types of samples. Analytical techniques applied in this field are normally focused ...
