Good old EDTA again – that’s a classic oldie indeed!
A few decennia ago, it even used to be infused directly into the bloodstream. Of course, this was only done in the extreme alternative circuit.
Perhaps you won’t mind if I add some information. This information is most easily accessible throught the Wikipedia page about EDTA, but of course it can be found in scientific articles too.
I quote from the Wikipedia page:
“EDTA […] degrades to ethylenediaminetriacetic acid, which then cyclizes to the diketopiperizide, a cumulative, persistent, organic environmental pollutant. […] It has been found to be both cytotoxic and weakly genotoxic in laboratory animals. Oral exposures have been noted to cause reproductive and developmental effects.”
Just for information…
