The integrated effect of various small arm weapons and ammunition types on the airborne lead levels

There is limited information regarding the integrated effect of various small arm weapons and ammunition types on the airborne lead levels. The aim of the present study was to evaluate whether the internal mechanical mechanism of gas-operated ammunition loading systems of weapons has an effect on airborne lead levels and to provide quantitative data on potential inhalation exposure of airborne lead. Remote-controlled firing under laboratory conditions was conducted in a closed shooting range with the Micro-Tavor (MT) and M16 automatic weapons with M193, Frangible, Brass, and Blank ammunition. The results of the study revealed higher airborne lead levels using M16 type weapon compared to the MT with all the ammunition types. The mean airborne lead levels were significantly ( p
