Determination of lead in forensic samples by atomic Absorption spectrophotometer

Determination of Lead (Pb) is very important in forensic samples specially in gunshot residue for identification of the shooter in a gunshot case. A simple and fast method of determination of Lead (Pb) by Atomic Absorption Spectrophotometer has got many advantages over other methods e.g colorimetric method in terms of reliability and accuracy of results. Swabs can be taken from hands with a suitable acid such as Hydrochloric Acid (HCl) or Nitric Acid (HNO₃) and the sample solution can be aspirated into the flame of an Atomic Absorption Spectrophotometer for determination of Lead (Pb) content. The present method is simple, rapid and reproducible and providing excellent quantification up to 0.05 ppm.
