This paper reports the determination of the firing distance and a method for the evaluation of the firing angle in a fatal incident caused by two gunshots. Neutron Activation Analysis (NAA) was used to determine the Sb pattern around the bullet entrance holes on a garment of the victim, and around bullet holes produced by different shots on test targets(More)
The possibility to have reference values in clinical chemistry is really important and hair is an ideal tissue for tracing human health conditions. This study performed on 131 hair samples of high school students gives a better knowledge of element levels (i.d., As, Cd, Cr, Cu, Fe, Hg, Mn, S, Sb, Se, Sn and Zn) in subjects not exposed to specific(More)
Human activities introduce compounds increasing levels of many dangerous species for environment and population. In this way, trace elements in airborne particulate have a preeminent position due to toxic element presence affecting the biological systems. The main problem is the analytical determination of such species at ultratrace levels: a very specific(More)
Bullet identification by chemical analysis often provides a powerful clue in forensic science. A case is reported in which a hunting accident was resolved by using instrumental neutron activation analysis (INAA) for direct comparison of the trace element content in lead shot. Different preparation batches of lead shot appear to have a high within-group(More)
BACKGROUND Anthropogenic activities introduce materials increasing levels of many dangerous substances for the environmental quality and being hazardous to human health. Major attention has been given to those elements able to alter the environment and endanger human health.The airborne particulate matter pollutant is considered one of the most difficult(More)
Many studies have focused their attention on the determination of elements of toxicological and environmental interest in atmospheric particulate matter using analytical techniques requiring chemical treatments. The instrumental nuclear activation analysis technique allows achieving high sensitivity, good precision, and excellent limit of detection without(More)
Multielemental detection using Instrumental Neutron Activation Analysis (INAA) and Proton-Induced X-Ray Emission (PIXE) of drinkable water of Florence (Italy) is described. The concentrations of 52 elements were measured. No chemical treatment was performed on the samples, before or after irradiation. On the basis of an appropriate combination of the two(More)
This case study describes the characterization of a suspect rod of nuclear fuel seized in Italy: on request of the coroner, the characterization concerned the kind and the conditions of the rod, the amount and the specific characteristics of the species present in it, with particular attention to their possible use chemical and/or nuclear plants. The(More)
