AbstractThe observation that Zr provided an estimate of soil ingestion 80% lower than estimates provided by seven other elements for 1 week in a soil‐pica child in light of the apparent high detection capability for the element resulted in a reexamination of the validity of a current modeling approach advocated for use in estimating soil ingestion detection limits. This examination reveals that for high levels of soil ingestion, possible biases in soil ingestion methodology may be inadequately accounted for in the soil detection limit model. The extent of this limitation is explored and placed in the context of reported limitations in trace element measurement methodology.
