How a Complete Pesticide Screening Changes the Assessment of Surface Water Quality
Christoph Moschet,Irene Wittmer,Jelena Simovic,Marion Junghans,Alessandro Piazzoli,Alessandro Piazzoli,Heinz Singer,Christian Stamm,Christian Leu,Juliane Hollender,Juliane Hollender +10 more
TL;DR: An extensive analytical screening was carried out using liquid chromatography-high-resolution mass spectrometry, covering 86% of all polar organic pesticides sold in Switzerland and applied to agricultural or urban land, plus 134 transformation products; each of which could be quantified in the low ng/L range.
Journal ArticleDOI
Alleviating the Reference Standard Dilemma Using a Systematic Exact Mass Suspect Screening Approach with Liquid Chromatography-High Resolution Mass Spectrometry
Christoph Moschet,Christoph Moschet,Alessandro Piazzoli,Alessandro Piazzoli,Heinz Singer,Juliane Hollender,Juliane Hollender +6 more
TL;DR: The efficiency of a suspect screening strategy using liquid chromatography-high resolution mass spectrometry without the prior purchase of reference standards was systematically optimized and evaluated for assessing the exposure of rarely investigated pesticides and their transformation products (TPs) in 76 surface water samples.
Journal ArticleDOI
Evaluation of in-situ calibration of Chemcatcher passive samplers for 322 micropollutants in agricultural and urban affected rivers.
Christoph Moschet,Etiënne L.M. Vermeirssen,Heinz Singer,Christian Stamm,Juliane Hollender,Juliane Hollender +5 more
TL;DR: It is concluded that only substances with relatively constant river concentrations can be quantified accurately in the field by passive sampling if substance-specific Rs are determined.
Journal ArticleDOI
LC- and GC-QTOF-MS as Complementary Tools for a Comprehensive Micropollutant Analysis in Aquatic Systems
TL;DR: The results highlight the importance of analyzing water samples using multiple separation techniques and in multiple ionization modes to obtain a comprehensive chemical contaminant profile.
Journal ArticleDOI
Household Dust as a Repository of Chemical Accumulation: New Insights from a Comprehensive High-Resolution Mass Spectrometric Study.
TL;DR: This study comprehensively characterizes chemicals in dust by applying a combination of target, suspect, and nontarget screening approaches using both LC and GC with quadrupole time-of-flight (Q/TOF) MS.
