Approximately 10 million tons of spent foundry sand (SFS) are generated in the United States each year,
and their beneficial use in agricultural and horticultural applications is being considered. Other studies
have demonstrated that trace elements are low enough in sands from iron, steel, and aluminum foundries
to allow their beneficial use. Because data were not available on polychlorinated dibenzo-p-dioxins, polychlorinated
dibenzofurans, and polychlorinated biphenyls in SFSs, we analyzed representative spent
sands from 10 foundries to assess the potential for these compounds to limit their use in soil-related
applications. The total TEQ (toxicity equivalent) concentrations ranged from 0.01 to 3.13 ng TEQ kg�1,
with an average concentration of 0.58 ng TEQ kg�1. These concentrations are within the range of natural
background in soils.
