Application of liquid chromatography/mass spectrometry in assessment of potential use of azadirachtins (TreeAzin ™ ) against Asian longhorned beetle
(Royal Society of Chemistry, 2014-08)
Azadirachtins are natural triterpenoid compounds derived from Neem tree extracts with potential for use as systemic insecticides against invasive wood-boring insect pests. In this work, a sensitive and selective analytical ...
Qualitative Screening of Undesirable Compounds from Feeds to Fish by Liquid Chromatography Coupled to Mass Spectrometry
(American Chemical Society, 2013)
This paper describes the development, validation, and application of a rapid screening method for the detection and identification of undesirable organic compounds in aquaculture products. A generic sample treatment was ...
Towards the review of the European Union Water Framework Directive: Recommendations for more efficient assessment and management of chemical contamination in European surface water resources
Water is a vital resource for natural ecosystems and human life, and assuring a high quality of water and protecting it from chemical contamination is a major societal goal in the European Union. The Water Framework Directive ...
Risk assessment for drugs of abuse in the Dutch watercycle
A screening campaign of drugs of abuse (DOA) and their relevant metabolites in the aqueous environment was performed in the Netherlands. The presence of DOA, together with the potential risks for the environment and the ...
Identification of mycotoxins by UHPLC–QTOF MS in airborne fungi and fungi isolated from industrial paper and antique documents from the Archive of Bogotá
Mold deterioration of historical documents in archives and libraries is a frequent and complex phenomenon that may have important economic and cultural consequences.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 ...
Eliminación de contaminantes emergentes en aguas residuales mediante oxidación avanzada con ozono y ultrasonidos
Algunos contaminantes emergentes, principalmente fármacos de diferentes clases así como drogas de abuso, pueden estar presentes en las aguas residuales urbanas, no siendo posible su eliminación mediante las técnicas ...
Novel analytical approach for brominated flame retardants based on the use of gas chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry with emphasis in highly brominated congeners
(American Chemical Society, 2015)
The analysis of brominated flame retardants (BFRs) commonly relies on the use of gas chromatography coupled to mass spectrometry (GC-MS) operating in electron ionization (El) and electron capture negative ionization (ECNI) ...
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 ...
Untargeted Metabolomics in Doping Control: Detection of New Markers of Testosterone Misuse by Ultrahigh Performance Liquid Chromatography Coupled to High-Resolution Mass Spectrometry
(American Chemical Society, 2015)
The use of untargeted metabolomics for the discovery of markers is a promising and virtually unexplored tool in the doping control field. Hybrid quadrupole time-of- flight (QTOF) and hybrid quadrupole Orbitrap (Q ...
Screening of Pesticides and Polycyclic Aromatic Hydrocarbons in Feeds and Fish Tissues by Gas Chromatography Coupled to HighResolution Mass Spectrometry Using Atmospheric Pressure Chemical Ionization
(American Chemical Society, 2014)
This paper reports a wide-scope screening for detection and identification of pesticides and polycyclic aromatic hydrocarbons (PAHs) in feeds and fish tissues. QuEChERS sample treatment was applied, using freezing as an ...
