The most soluble chemical species are generally the most toxic. The toxicity of metals and metalloids depends on the chemical form and speciation. Joensuu: North Carelia Regional Environment Centre. Survey and risk management of soils at shooting ranges. The pieces of clay targets therefore tend to accumulate within a limited area.ДЄ Small amounts may occur in some shot types. The fragmented clay targets fall within the maximum distance of approximately 60В m from the shooter, the distance of missed targets is a bit longer.

The dispersion of the pellets is also to a great extent affected by the landscape, for example, whether there are obstacles along the flight path. The positioning and number of traps determine the overall spatial distribution of the pellets. In trapshooting, the distribution of shot follows the same rule of thumb, the only difference being the angle of the sector (approximately 90 degree). Therefore, pellets with the size of 2В mm in skeet shooting would fall within a sector with an angle of approximately 150 degree and radius of some 200В m from each single station. Generally, the flight distance in 100В m is approximately the same as the diameter of the pellet in millimeter. The length of the flight path of each pellet depends on its size. In the shooting event, the pellets quickly disperse after leaving the gun and spread around the impact area ( Fig.В 1). The ammunition used in all types of shotgun shooting is a cartridge that contains up to a few hundred of small pellets (shot). The intention of this setup is to simulate actual hunting situations, that is, shooting of game birds. In addition, there are sporting ranges in which the traps and stations are vary situated along a short course and the clay targets are thrown from several traps using different angles and speeds. Depending on the number and position of the traps and shooting positions (stations), difference is made between skeet and trapshooting. In shotgun shooting, the aim is to hit the clay targets (i.e., clay pigeons) launched from specific throwing devices, that is, traps. The main types of small-arms shooting activities comprise shotgun, rifle, and pistol shooting.
