This study evaluates heavy-metal contamination in soils affected by military activities using training areas as proxies for conflict zones. Soil samples from a shooting range and a grenade range were analyzed using XRF and FAAS after mineralization. High concentrations of Cu, Ni, and Pb were detected, with extreme Pb levels at the shooting range exceeding preventive values. The results support the use of military training sites for developing remediation strategies applicable to war-affected regions. The study provides a relevant proxy-based approach to assess contamination under restricted field conditions and highlights contamination specificity linked to military activities.

The possibilities of nanoparticles fabrication from the selected metals: copper, brass and 18Cr9Ni steel by laser ablation method were investigated. For the nanoparticles extraction process the most favorable pulse laser parameters were selected such as: laser beam power, number of laser pulses and distance of the beam focus from the metal foil. The SEM analysis confirmed the presence of nanospheres and nanowires geometry of metal particles.
