“…The United States has about 3000 military and 9000 civilian shooting ranges with an estimated annual Sb deposition of 1900 tons (Wan et al, 2013a). Shooting ranges have recently come into the focus of public concern also in other countries, notably Finland (Sorvari et al, 2006;Sorvari, 2007), Norway (Stromseng et al, 2009), andCanada (Laporte-Saumure et al, 2011). Antimony concentrations in ground (Wersin et al, 2002) and stream water samples (Stromseng et al, 2009;Heier et al, 2010) in the vicinity of shooting ranges have been found to exceed background concentrations by a factor of more than 20 in some studies, indicating a potential risk of uncontrolled Sb release from such sites.…”
