Overview
Environmental contamination may result in important health effects. In order to assess these potential effects, it is necessary to have an estimate of exposure to the contaminant. An important route of exposure to contaminants, particularly among children, is through ingestion of contaminated soil. Exposure is typically estimated by multiplying the the concentration of the contaminant in soil by the amount of soil ingested. As a result, an estimate of the amount of soil ingested is needed. This research aims to estimate the amount of soil ingested by children.
It is likely that most children ingest soil, but that the amount of soil ingested by a child differs from one day to the next, and differs between children. Ideally, risk assessors would like to know what the distribution of soil ingestion is for children. For a given child, the distribution of soil ingestion over days is also of interest. This research aims to estimate the distribution of soil ingestion over children, and the distribution of soil ingestion over days for a given child.
Estimates of children's soil ingestion distribution are constructed from mass-balance research studies conducted on children. At this website, we describe such studies, and provide basic data. Methods for combining study results, and for individual studies are given. Finally, estimates of the distribution of soil ingestion over children, and the distribution of soil ingestion over days for a given child are constructed.
