Accounting for bioavailability in contaminated land site-specific health risk assessment

Publication date:  August 2016
Publication reference number:  CR 231

This report presents the findings of research into the potential adoption of a bioavailability assessment methodology for soil contaminants in New Zealand. For the purpose of this document, bioavailability is the proportion of a substance that is absorbed from soil in the digestive system into the body.

The research concludes that a United States Environmental Protection Agency method meets relevant scientific, economic and social assessment criteria, and therefore could be adopted in New Zealand.
