A firearm shot is a complicated physico-chemical process in where the by-product of the shot is a shotfire product that contains both metallic and non-metallic micro and nanoparticles. The main aim of the experiment was to verify the efficiency of respirators against gunshot residues from pistol shooting on an indoor shooting range and testing the phytotoxicity of sediment particles taken from the shooting range floor. The experiments were focused on measuring their concentration of an observer (range 20-1000 nm) after gunshots residues (GSR) from pistol. The various types of respirators detected particles penetration. The efficiency was calculated from the measured values especially their FIT factor and S (%) - efficiency of protective equipment. The most efficient respirator was considered REFIL 651 (FIT factor = 93, S = 98.9. The samples from the shot fills were further tested on their phytotoxicity - a component of environmental toxicity. The test of phytotoxicity was conducted from specific places at a distance of 1 m and 3m from the boxes. The root growth inhibition IC (%) for 1 m was 65.84, for 2 m 75.08. The toxic effect of sediment particles might be considered high. The measurement proved the growth of nano- and microparticles by 3 digits in comparison to the standard in a normal atmosphere. The results should inspire the shooting range operators to extend the use of the personal protective equipment to respirators, along with hearing protectors and goggles and lastly to threat the deposit as a dangerous waste.
