CAN CADAVEROUS POLLUTION FROM ENVIRONMENTAL LEAD MISGUIDE TO FALSE POSITIVE RESULTS IN THE HISTOCHEMICAL DETERMINATION OF GUNSHOT RESIDUES? STUDY ON CADAVERIC SKIN SAMPLES

The histochemical Sodium Rhodizonate Test (Na-R) and 5% HCl Sodium Rhodizonate Test (Na-R-HCl), are techniques used in Italy and considered very useful in the study of gunshot wounds, in the determination of the shot distance [1,2] and in the differential diagnosis between the entry and exit hole [3]. These techniques are considered fundamental since energy-dispersive X-ray spectroscopy (SEM/EDX) has high costs and is not available in all laboratories. The features of gunshot wounds are macroscopically appreciable when the body is well preserved, but if the bad cadaveric conditions do not allow to understand the nature of the lesions [4], it is necessary to address such bodies (if a gunshot wound is suspected) to the histological detection of gunshot residues in a region protected from environmental pollution, such as the way of the projectile inside the body.
