To conclude, some ancient cosmetics were indeed potentially dangerous, especially if used regularly over a prolonged length of time.
This was confirmed by Van der Burg’s analysis in exhumed bodies by means of the arsenic mirror method developed by Marsh some years before.
Van der Burg and his successors continued to play a central role in forensic toxicology until the 1950 when the Central Laboratory of Forensic Sciences, now the Netherlands Forensic Institute, was founded.
, due to its golden color, was used in ancient times as a pigment and dye, while realgar was a common red pigment for paints and dyes.
Realgar decomposes in air to a yellow-orange compound para-realgar; consequently, old unrestored paintings have a yellow-orange tinge over a red color.The first lecturer in toxicology was the physician A. In 1848 he published a book entitled (The Need to Regulate the Use of Venoms).
