Because of its variability and uncertainty, the rate of soil ingestion is a critical characteristic for environmental exposure assessment. Various estimates and uncertainties are described here. We propose an operational framework for selecting values for this variable in different exposure circumstances. Uncertainty due to misuse of data can be reduced, in particular by avoiding the use of short-term estimates of soil ingestion rates for assessing chronic exposure.
