title: Distribution of antimony in contaminated grassland: 1--Vegetation and soils.
abstract: Antimony concentrations in surface soils were found to decrease with increasing distance from an antimony smelter. This pattern was also found in moss bags exposed in the same area. At three sites close to the smelter, antimony concentrations in soil and vegetation were much higher than at a rural control site and published background levels. Maximum soil and plant concentrations on a dry weight basis of 1489 mg kg(-1) and 336 mg kg(-1), respectively, were found, compared to background levels of <1 mg kg(-1). Field exposure of grass in pots of uncontaminated soil and a laboratory experiment using soils from near the smelter suggested that the antimony in vegetation was largely due to continued aerial deposition and not to uptake from soil.
