So, I'm thinking about homebrew and went looking for PG & VG suppliers (links below). The glycerine, although meeting EU food additives regulations, appears to contain arsenic, lead, mercury and cadmium. Tiny concentrations, but given how much we do this, is there cause for concern, and crucially, does all glycerine contain these elements or have I just picked a crap supplier?
To be fair, all these elements are present in cigarettes, and my own feeling is I probably take in more of this stuff just breathing city air, but I thought I'd flag it up. I'm getting my knickers in a twist about the whole PG vs VG thing at the mo.
