How should garden vegetable samples be collected for use in the IEUBK model?
The alternate dietary values feature of the IEUBK model is intended to enable risk assessors to predict impacts of ingestion of lead contained in locally-harvested foods (e.g., fruits, vegetables and game) on blood lead concentrations of children. This feature can be used when site-specific data are available to estimate both the concentration of lead in these food sources and the contributions that these food sources make to the diet of a typical child at the site. Lead exposure concentration: The exposure concentration term should represent the concentration to which children are exposed; that is, it should be an estimate of the concentration of lead in the food as prepared for ingestion. To ensure that the measurements of lead in home-grown vegetables reflect the expected exposure concentrations as closely as possible, measurements should be made on vegetables that have been prepared for ingestion. In addition, in deriving the concentration term and interpreting the results of IEUBK
