Consumer Reports found that several brands of ground cinnamon contain #lead . It begs the question of: what about other ground spices? Many places around the world don't follow good food safety standards. They're not tested at the border when imported. A great project for someone with the equipment would be to test various spices from various places. Maybe other common contaminants too. It would be a great study. Let me know if you do -- happy to write about it.
And, what about spices in #Canada? Many come from the same sources.
ADDENDUM: Another thought. Maybe some of those long-term, large population studies could test for lead, etc. in some of the blood samples they collect. Could be a good indicator.

Orbitrap or QTOF? While many would expect that Orbitraps perform better because of their higher mass resolution, it turns out that it’s more complicated than that. In many cases QTOFs outperform Orbitraps because of their larger dynamic range. #masspec

Today, we updated #MassBankEU to system version 2.2.3. and deployed MassBank-data release 2023.06 (DOI: 10.5281/zenodo.8005857). We added new spectra provided by Agilent Technologies, Eawag, MSSJ, LCSB and US EPA CCTE.

We are hiring a postdoctoral scholar in non-targeted analysis to help us find previously unknown chemicals that people are exposed to. The position is at NYU in New York City.

For the last 4 years, I've been part of the consortium, working on the TopSpec Project, funded by the EU, to develop "the most sophisticated platform for top-down analysis of intact proteins".

My part is only small - but the project is awesome!
