Abstract Background The NORMAN Association ( https://www.norman-network.com/ ) initiated the Suspect List Exchange (NORMAN-SLE; https://www.norman-network.com/nds/SLE/ in 2015, following collaborative trial on non-target screening of environmental water samples by mass spectrometry. Since then, this exchange information chemicals that are expected to occur environment, along with accompanying expert knowledge and references, has become a valuable base for “suspect screening” lists....
There is growing worry that drinking water can be affected by contaminants of emerging concern (CECs), potentially threatening human health. In this study, a wide range CECs (n = 177), including pharmaceuticals, pesticides, perfluoroalkyl substances (PFASs) and other compounds, were analysed in raw collected from treatment plants (DWTPs) Europe Asia 13). The impact activities was reflected large numbers compounds detected 115) high variation concentrations the (range 15-7995 ng L−1 for...
Photodegradation of plastic consumer products is known to accelerate weathering and facilitate the release chemicals particles into aquatic environment. However, these processes are complex. In our presented pilot study, eight were leached in distilled water under strong ultraviolet (UV) light simulating months Central European climate compared their respective dark controls (DCs). The leachates formed exploratorily characterized using a range chemical analytical tools describe degradation...
Pesticides are widespread anthropogenic chemicals and well-known environmental contaminants of concern. Much less is known about transformation products (TPs) pesticides their presence in the environment. We developed a novel suspect screening approach for not well-explored (n = 16) pesticide TPs 242) by integrating knowledge from national monitoring with high-resolution mass spectrometry data. Weekly time-integrated samples were collected two Swedish agricultural streams using...
Only a few dozens of the several thousand existing per- and polyfluoroalkyl substances (PFAS) are monitored using conventional target analysis. This study employed suspect screening to examine patterns emerging novel PFAS in German Chinese river water affected by industrial point sources. In total, 86 were (tentatively) identified grouped into 18 structure categories. Homologue revealed distinct differences between fluoropolymer production sites two countries. Xiaoqing River Basin, C8...
In recent years, high-resolution mass spectrometry (HRMS)-based studies have highlighted an increasingly complex 'PFAS world' and thousands of per- polyfluoroalkyl substances (PFAS) are known today. Major new discoveries were made when previously unexplored PFAS sources or transformation pathways investigated HRMS was combined with other analytical methods. Advances in analysis data treatment pointed to blind spots, extensive suspect screening lists evaluation approaches become available....
The hyphenation of ion mobility separation (IMS) with high-resolution mass spectrometry (HRMS) presents a milestone in the screening organic micropollutants (OMPs) complex environmental matrices. Its use has become progressively more widespread analysis and led to development novel analytical strategies. This work provides comprehensive overview advantages using IMS-HRMS instrumentation, special focus on studies. IMS an additional parameter for OMP identification, reduction spectral...
Wastewater treatment plants (WWTPs) are known point sources of contaminants emerging concern (CECs) to the aquatic environment, but current knowledge is mostly limited well-known chemical structures. In this study, we sought identify unknown CECs polluting environment through a novel suspect screening approach for organohalogens, i.e. organic halogenated molecules often toxic and resistant transformation characterised as persistent pollutants (POPs). Surface water samples were collected with...
Abstract Non-target analysis (NTA) employing high-resolution mass spectrometry is a commonly applied approach for the detection of novel chemicals emerging concern in complex environmental samples. NTA typically results large and information-rich datasets that require computer aided (ideally automated) strategies their processing interpretation. Such do however raise challenge reproducibility between within different workflows. An effective strategy to mitigate such problems implementation...
Identification of bioaccumulating contaminants emerging concern (CECs) via suspect and non-target screening remains a challenging task. In this study, ion mobility separation with high-resolution mass spectrometry (IM-HRMS) was used to investigate the effects drift time (DT) alignment on spectrum quality peak annotation for CECs in complex sample matrices using data independent acquisition (DIA). Data treatment approaches (Binary Sample Comparison) prioritisation strategies (Halogen Match,...
Environmental monitoring studies based on target analysis capture only a small fraction of contaminants emerging concern (CECs) and miss pollutants potentially harmful to wildlife. specimen banks, with their archived samples, provide opportunities identify new CECs by temporal trend non-target screening. In this study, white-tailed sea eagle (Haliaeetus albicilla) muscle tissue was analysed non-targeted high-resolution mass spectrometry. Univariate statistical tests (Mann-Kendall Spearman...

Abstract. Der bislang größte Schädel von Bos primigenius wurde in den Ablagerungen des Oberrheins Groß-Rohrheim bei Darmstadt gefunden. Stratigraphisch wird er mit allergrößter Wahrscheinlichkeit dem letzten Interglazial zugeordnet. Die Maße übersteigen alle Messwerte, die pleistozänen und holozänen Auerochsen Mitteleuropas bekannt sind. Vergleichbare gibt es am ehesten aus Pleistozän Italien. Das mag ein Hinweis auf besonders günstige ökologische Bedingungen sein, zumal der Auerochse...
