Antimony (Sb) is a naturally occurring trace element in the earth's crust, and it is a non-essential element for life processes. The average concentration of Sb in soil is about 0.48 mg kg −1, and soil levels of Sb are much higher in antimony-processing sites and hazardous waste sites (ATSDR 1992).There is much concern regarding Sb pollution …
