I was quite surprised they didn't find any silicon because the stopper has silicon oil, and the glass is an aluminum-silicate compound (Valor glass from Corning which can stand -80C)

Why report in ug/L instead of ppm or ppb as toxicologists do, or better yet, nmol/L? That way we can compare to standard acceptable limits.

Finally, this sampling issue has me quite perplexed. Li for example. It was used in the manufacturing of the PEG lipid and levels were below acceptable limits but because it was part of the starting materials, I would expect it to be in all batches of PEG lipid. Yet they found large amounts in one Pfizer vial and none in another one.

I agree with your assessment. Not totally junk science but there are lots of unanswered questions.

Ja, auf die Elemente kommt es selten an. In welchen Verbindungen sie vorliegen, ist wichtig.

Zum Beispiel:

NaOH - Natronlauge ist ziemlich giftig

NaCl - Kochsalz ist lebenswichtig
