Extensive research indicates that propellant residues accumulate at firing positions and represent a concern for the environment and human health. To better understand the impacts of live firing at firing positions, a series of characterizations was conducted to measure the deposition of propellant residues from many sources. The present study was conducted three times with Leopard tanks firing 105-mm tank gun ammunition. The first trial was carried out at CFB Gagetown where no propellant residues were identified. For validation purposes, two additional trials were conducted at CFB Valcartier. DRDC Valcartier assessed the particles emitted, the gaseous emissions, and the particles size distribution during these live-fire events. Gases were collected in front of and inside the tank and the results from the gaseous emissions study will be described in another report. This paper describes the results obtained on the deposition of propellant residues during tank live firings. In November 2008, the setup consisted of half circles of particle traps disposed at 1, 5, 10, 15, 20, 30 and 40 m in front of the tank. Ethanol was poured inside the traps to contain the particles emitted during firing. Following the first set of firings, many traps were destroyed, some caught fire, and the experiment had to be stopped. During this event, since the gaseous collection system was adequate, it was decided to continue the firing to measure the gaseous emissions. The particle collection experimen
