Lead diacetate

Lead acetate is a chemical compound made by treating lead(II) oxide with acetic acid. Due to its sweet taste, it was used as a sweetner before its toxicity was recognized. Today it can be found in low concentrations in some hair dyes. Lead is a heavy metal and stable element with the symbol Pb and the atomic number 82, existing in metallic, organic, and inorganic forms. It is mainly found in nature as the mineral galena (PbS), cerussite (PbCO3) or anglesite (PbSO4), usually in ore with zinc, silver, or copper. (L21, L405) — Toxin and Toxin Target Database (T3DB)
