Thallium, right between Pb and Hg on the period table. Czech is in the EU, surprised they allowed the study. It appears as though Tl is easily absorbed into Rapeseed, but how much gets into canola post extraction and processing?
*note: Thallium has some of the following toxic pathophysiological effects:
1. Disruption of potassium-dependent processes
2. Riboflavin sequestration
3. Interference with cysteine residues
4. Ribosomal inhibition
5. Myelin sheath injury
