Soil Ingestion in Children-Meta Analysis Website

This site contains:

• data sets from selected basic mass-balance soil ingestion studies conducted in children
• methods for combining such data in a meta analysis to estimate the distribution of soil ingestion over children, and the distribution of soil ingestion over days for a child
• the results of the meta analysis.

Soil ingestion estimates are an important component of an exposure assessment study when soil is contaminted. The results of the meta analysis provides the information that can be used to estimate distributions that can serve as a foundation for soil ingestion in a Monte-Carlo exposure assessment in children. This research site provides details for the underlying studies, data, and models used to estimate the soil ingestion distributions.

Soil ingestion studies documented in this site include the Amherst study (Calabrese et al. 1989, the Washington State study (Davis et al., 1990), the Anaconda study (Calabrese et al., 1997; Stanek et al. 1999), and the Soil Pica study in Western Massachusetts (Calabrese et al. 1997).

The results of the meta analysis, sensitivity analyses, and a review and discussion limitations of the data is included.
