Daniel Petras @daniel-petras.bsky.social · 17/03/2026Our new paper on the presence of xenobiotics in marine dissolved organic matter just come out. Thanks to Jarmo Kalinski and our awesome collaborators, we were able to reanalyze more than 20 public LC-MS/MS datasets from seawater and ask how many anthropogenic compounds we can detect. rdcu.be/e8q6C 22013
Daniel Petras @daniel-petras.bsky.social · 07/02/2026I am super excited that our paper on inter-laboratory comparability of non-targeted LC–MS/MS analysis of dissolved organic matter was just published in ES&T. pubs.acs.org/doi/10.1021/... 6176
Daniel Petras @daniel-petras.bsky.social · 17/09/2025In a large community effort with 50 coauthors, we analyzed the same set of marine dissolved organic matter samples across 24 laboratories via non-targeted LC-MS/MS, to check if we get comparable data. If you want to check it out, you can find our preprint here: doi.org/10.26434/che... 071

Big congrats to Reza and Ming @mingxunwang.bsky.social et al. and thanks a lot for letting us play around with it. www.biorxiv.org/content/10.1... 064
