Degradation of seventeen contaminants of emerging concern in municipal wastewater effluents by sonochemical advanced oxidation processes
(Elsevier, 2019)
The simultaneous degradation of seventeen emerging concern pollutants in effluent
from the municipal wastewater treatment plant (MWTP) of Bogotá-Colombia was
studied using high frequency ultrasound (375 kHz). The considered ...
A simple and rapid analytical methodology based on liquid chromatography - tandem mass spectrometry for monitoring pesticide residues in soils from Argentina
(Royal Society of Chemistry, 2015)
Rapid analytical methodology has been developed for multi-residue
determination of pesticides in soils using liquid chromatography coupled to tandem
mass spectrometry (LC-MS/MS) with triple quadrupole analyzer. Soil ...
Assessing geographical differences in illicit drug consumption – A comparison of results from epidemiological and wastewater data in Germany and Switzerland
(Elsevier, 2016-04-01)
Background: Wastewater analysis is an innovative approach that allows monitoring illicit drug use at the community level. This study focused on investigating geographical differences in drug consumption by comparing ...
‘An investigation into the occurrence and removal of pharmaceuticals in Colombian wastewater’
(Elsevier, 2018)
In this work, the presence of 20 pharmaceuticals in wastewater from Colombia is investigated. Several widely consumed compounds have been detected in wastewater samples from different origins and geographical areas in ...
Bogota River anthropogenic contamination alters microbial communities and promotes spread of antibiotic resistance genes
(Nature Research, 2019)
The increase in antibiotic resistant bacteria has raised global concern regarding the future effectiveness of antibiotics. Human activities that influence microbial communities and environmental resistomes can generate ...
Improvements in the analytical methodology for the residue determination of the herbicide glyphosate in soils by liquid chromatography coupled to mass spectrometry
(Elsevier, 2013-05)
The determination of glyphosate (GLY) in soils is of great interest due to the widespread use of this herbicide and the need of assessing its impact on the soil/water environment. However, its residue determination is very ...
Direct liquid chromatography–tandem mass spectrometry determination of underivatized glyphosate in rice, maize and soybean
(Elsevier, 2013-10)
The residue determination of the widely used herbicide glyphosate (GLY) is highly problematic due to its amphoteric character, low mass and lack of chemical groups that might facilitate its detection. Most methods developed ...
Occurrence of antibiotics and bacterial resistance in wastewater and sea water from the Antarctic
(Elsevier, 2018-10)
The potential presence of introduced antibiotics in the aquatic environment is a hot topic of concern, particularly in the Antarctic, a highly vulnerable area protected under the Madrid protocol. The increasing presence ...
Investigating the presence of omeprazole in waters by liquid chromatography coupled to low and high resolution mass spectrometry: degradation experiments
(John Wiley & Sons, 2013-09)
Omeprazole is one of the most consumed pharmaceuticals around the world. However, this compound is scarcely detected in urban wastewater and surface water. The absence of this pharmaceutical in the aquatic ecosystem might ...
Combined use of liquid chromatography triple quadrupole mass spectrometry and liquid chromatography quadrupole time-of-flight mass spectrometry in systematic screening of pesticides and other contaminants in water samples
(Elsevier, 2013-01-25)
As a suitable way for routine screening of pesticides and control of other organic contaminants in water, the combination of liquid chromatography triple quadrupole tandem mass spectrometry (LC–QqQ-MS/MS) and liquid ...
