Fantastic environment, dynamic projects, high-tech facilities, cutting-edge research. What are you waiting for? ⏬️⏬️⏬️

[May Britt Rian @MayBrittRian]

How will your choice of #HRMS acquisition strategy affect molecular coverage, structural annotation and MS2-based toxicity predictions with #MS2Tox in your #Nontarget analysis? Check out our recent publication in @EnvSciTech 🥳

#OpenAccess: https://t.co/Z1nvtokcdt

[Hongyu Xie @HongyuXie9]

We are very #HA-P (happy) to see that our #HA-P method is now published on @EnvSciTech for sensitive and quantitative #Chemical #Exposomics by #GC- #HRMS. https://t.co/NFfEpnP8uO

[Kalliroi Sdougkou @sdougkou]

Our longitudinal #exposomics study is now available in @EnvSciTech. We show valuable cohort-scale data on the longitudinal stability of #exposome in blood, discuss unique coexposures and define longitudinal exposure types, useful for study design. https://t.co/AhEzW0Tw84

This PhD will be part of the FELIX project (https://t.co/VfT5cb8iYp) & the ReproManDo project (https://t.co/JJTWvJ0z1Q)

Interested in figuring out the link between the chemical #Exposome and #Endocrine disruption in pet animals using #LC & #GC #HRMS? A #PhDposition is open @AcesSthlmUni @Stockholm_Uni
You can apply until the 15th of August!

I'm glad to share that I will be leading the coming @NORMAN_network Trial on "Non-target screening of airborne organic substances in PDMS-foam passive samplers". Registration is currently open (https://t.co/v9jEFfvBAD) and the deadline is July 1st 2024. Don't miss it!

[Hongyu Xie @HongyuXie9]

Please check our latest @ChemRxiv study: sensitivity for plasma chemical #exposomics was enhanced by lipid removal and large volume injection #GC-#HRMS, resulting high target detection, nontarget annotation and molecular confirmation rates.

[Kalliroi Sdougkou @sdougkou]

Check our @biorxivpreprint for the first cohort-level longitudinal #exposomics application in blood. We show that #exposome longitudinal stability is lower than other biomolecular profiles and discuss novel co-exposures relevant to #PrecisionMedicine.

[Adrià Sunyer Caldú @ASunyerCaldu]

We are looking for a laboratory assistant in our group to provide analytical chemistry support for the trace analysis of organic chemicals in indoor and outdoor air samples within @INQUIRE_EU project at @AcesSthlmUni. Closing date: 13th March https://t.co/4bLC7EUc7J @AcademicTox

[Adrià Sunyer Caldú @ASunyerCaldu]

Few days left to submit your abstract! Deadline on 29 November 2023. We hope to see many of you in the beautiful Seville and discuss about #exposome! @SETAC_world

[Craig Wheelock @CraigWheelock]

Come join us in Stockholm! We are searching for our next colleague to perform #postdoctoral studies on #lipid mediator #massspectrometry. Develop LC-MS/MS & SFC-MS/MS methods to probe the role of lipids in #asthma. Long-term career development options! https://t.co/LRXrUGeXDy

[Jon Martin @AcademicTox]

Here is more about the Assistant Professor position available here at ACES. Please alert any of your colleagues in #toxicology with interest in #computational and #machinelearning methods. Let me know if any questions...

[Jon Martin @AcademicTox]

Early career toxicologists take note. We are recruiting an assistant prof in data-driven life science ($1.6 M USD startup). We are looking for computational and AI approaches to study (eco)toxicology, ranging from molecular and cellular response to health. https://t.co/FNmg8P6p8i

[Hans Peter Arp @hanspeterarp]

The purpose of the new chemical hazard classes #PMT and #vPvM are to prevent persistent substances like #PFAS from entering and accummulating in #water resources

A recent paper criticized the #PMT criteria based on misconceptions.

We clarified:

I struggle to find better evidence of the importance of full transparency and third-party review in chemical assessment. Axel Mie & @christina_ruden reveal recurring non-disclosure of studies by the pesticide industry resulting in a public hearing on July 18 at the @EUparliament.

[Bénilde Bonnefille @Benilde_B]

To our knowledge the #herbicide #fenuron has never been reported in human biofluids but was detected in 56% of 34 swedish plasma samples, while never approved in #Sweden. It was detected along with other chemicals, e.g. personal care products, and endogenous steroids hormones 3/3

[Bénilde Bonnefille @Benilde_B]

New work by @sdougkou and our group!
Removing #plasma #phospholipids allowed to increase the intensities of non-phosholipid features up to 58 times and the detection of up to 109% (!) more non-phosholipid features 1/3
@AcademicTox @PapazianStefano @HongyuXie9 & Ingvar A. Bergdahl

[Kalliroi Sdougkou @sdougkou]

How to increase sensitivity for chemical #exposomics in the complex plasma matrix? Read on our new method in @EnvSciTech. Application in samples from #Sweden and more coming soon!

Phospholipid Removal for Enhanced Chemical Exposomics in Human Plasma
https://t.co/0jbIIYweu5

[Bénilde Bonnefille @Benilde_B]

The phospholipid removal allowed a better detection and quantification of some #PFAS (PFDA and PFUnDA) compared to data already published on these samples. PFAS precursors were also detected and semi-quantified, as well as branched isomers 2/3
