Can cadaverous pollution from environmental lead misguide to false positive results in the histochemical determination of Gunshot Residues? In-depth study using ultra-sensitive ICP-MS analysis on cadaveric skin samples

On these basis, we can state that environmental Pb does not contaminate cadavers exposed to open air nor those buried in soil, as confirmed using to ICP-MS technique. Sodium Rhodizonate and 5% HCl Sodium Rhodizonate confirmation test have therefore a high sensitivity, highlighting GSRs, for the diagnosis of death caused by firearm wounds.
