Soil quality. Assessment of human exposure from ingestion of soil and soil material. Procedure for the estimation of the human bioaccessibility/bioavailability of metals in soil Ingestion-build-47182 measurement of degrees of freedom1 Scope This document deals with the assessment of human exposure from ingestion of soil and soil materials. It specifies a physiologically based test procedure for the estimation of the human bioaccessibility of metals from contaminated soil in connection with the evaluation of the exposure related to human oral uptake. The method is a sequential extraction using synthetic gastrointestinal fluids and can be used to estimate oral bioaccessibility.
