Building an empirical mass spectra library for screening of organic pollutants by ultra-high-pressure liquid chromatography/hybrid quadrupole time-of-flight mass spectrometry
John Wiley (2011-01-30)Hybrid quadrupole time-of-flight mass spectrometry (QTOF MS) has gained wide acceptance in many fields of chemistry, for example, proteomics, metabolomics and small molecule analysis. This has been due to the numerous ... -
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 ... -
Development and validation of a rapid and wide-scope qualitative screening method for detection and identification of organic pollutants in natural water and wastewater by gas chromatography time-of-f.
© 2010 Elsevier (2011-01)In this work, a multiclass screening method for organic contaminants in natural and wastewater has been developed and validated for qualitative purposes, i.e. to ensure the reliable and sensitive identification of compounds ... -
Identification of mycotoxins by UHPLC–QTOF MS in airborne fungi and fungi isolated from industrial paper and antique documents from the Archive of Bogotá
Elsevier (2016-01)Mold deterioration of historical documents in archives and libraries is a frequent and complex phenomenon that may have important economic and cultural consequences. In addition, exposure to toxic fungal metabolites might ... -
Investigation of pesticides and their transformation products in the Júcar River Hydrographical Basin (Spain) by wide-scope high-resolution mass spectrometry screening
Elsevier (2019-10)The Water Framework Directive 2000/60/EC implemented by the European Union established as the main objectives to achieve a “good ecological and chemical status” of the surface water and a “good quantitative and chemical ... -
Investigation of pharmaceuticals and illicit drugs in waters by liquid chromatography-high-resolution mass spectrometry
Elsevier (2014)Mass spectrometry (MS) coupled to chromatography has been increasingly used in the environmental field, as it allows the best performance currently attainable for the investigation of a wide range of organic pollutants. ... -
Occurrence and ecological risks of pharmaceuticals in a Mediterranean river in Eastern Spain
Elsevier (2020-11)Pharmaceuticals are biologically active molecules that may exert toxic effects to a wide range of aquatic organisms. They are considered contaminants of emerging concern due to their common presence in wastewaters and in ... -
Screening and quantification of pesticide residues in fruits and vegetables making use of gas chromatography-quadrupole time-of-flight mass spectrometry with atmospheric pressure chemical ionization
Springer (2014-11)An atmospheric pressure chemical ionization source has been used to enhance the potential of gas chromatography coupled with quadrupole time-of-flight (QTOF) mass spectrometry (MS) for screening and quantification purposes ... -
UHPLC-QTOF MS screening of pharmaceuticals and their metabolitesin treated wastewater samples from Athens
Elsevier (2017-02)After consumption, pharmaceuticals are excreted as parent compounds and/or metabolites in urine and faeces. Some are not completely removed during wastewater treatments, forcing sewage treatment plants (STPs) to apply ... -
Validation of a qualitative screening method for pesticides in fruits and vegetables by gas chromatography quadrupole-time of flight mass spectrometry with atmospheric pressure chemical ionization
Elsevier (2014-08-01)A wide-scope screening method was developed for the detection of pesticides in fruit and vegetables. The method was based on gas chromatography coupled to a hybrid quadrupole time-of-flight mass spectrometer with an ... -
Wide-scope screening of pharmaceuticals, illicit drugs and their metabolites in the Amazon River
IWA Publishing (2021-05-17)Only a limited number of households in the Amazon are served by sewage collection or treatment facili- ties, suggesting that there might be a significant emission of pharmaceuticals and other wastewater contaminants into ...
