The role of analytical chemistry in exposure science: Focus on the aquatic environment
(Elsevier, 2019-05)
Exposure science, in its broadest sense, studies the interactions between stressors (chemical, biological, and physical agents) and receptors (e.g. humans and other living organisms, and non-living items like buildings), ...
Estimation of illicit drug use in the main cities of Colombia by means of urban wastewater analysis
(Elsevier, 2016-09)
Wastewater-based epidemiology (WBE) relies on the principle that traces of compounds, which a population is exposed to or consume, are excreted unchanged or as metabolites in urine and/or feces, and ultimately end up in ...
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 ...
Exploring matrix effects in liquid chromatography–tandem mass spectrometry determination of pesticide residues in tropical fruits
(2015-12-17)
Tropical fruits are being increasingly consumed around the world because of their appreciated characteristics, particularly their high nutritional value and distinctive taste, which are different from those of traditional ...
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 ...
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 ...
Chromatography hyphenated to high resolution mass spectrometry in untargeted metabolomics for investigation of food (bio)markers
(Elsevier, 2021-02-01)
Currently, there is a growing demand by our society, authorities and science to increase the
knowledge about the quality of food and its relationship with health and disease. Untargeted
metabolomics approaches are emerging ...
Perspectives and challenges associated with the determination of new psychoactive substances in urine and wastewater – A tutorial
(Elsevier, 2021-02-08)
New psychoactive substances (NPS), often designed as (legal) substitutes to conventional illicit drugs, are constantly emerging in the drug market and being commercialized in different ways and forms. Their use continues ...
