On a local scale, Sb can make its way into soil through the application of lead arsenate pesticides, since Sb is present as a contaminant in the Pb- and As-containing ores used to manufacture pesticides (Wagner et al., 2003). The antimony concentration is less than 1 μg L −1 and within the lower mg kg −1 range in uncontaminated water and soils, respectively (Lintschinger et al., 1998b, Lintschinger et al., 1998a, Filella et al., 2002a, Filella et al., 2002b). Filella et al., 2002a, Filella et al., 2002b reported an excellent review on Sb in the environment. It is likely that antimony can be mainly released to the environment in the form of antimony containing metal alloys, flame retardants, and catalysts such as antimony trioxide or pentoxide (Sb 2O 3 and Sb 2O 5, respectively) (Maeda, 1994). Antimony is released into the environment from a number of anthropogenic sources. Naturally occurring antimony is largely present as Sb 2S 3 (stibinite) and Sb 2O 3 (valentinite), and it has no known biological role. It is also commonly used in products such as brake linings, antiparasitic agents, polyethylene terepthalate (PET or PETE) plastics, bullets, flame proofing compounds, and as an additive in the tire vulcanization process (Lintschinger et al., 1998b, Lintschinger et al., 1998a, Krachler et al., 2001, Krachler and Emons, 2001, Shotyk et al., 2006). ![]() Antimony is a trace element occurring naturally in soils.
