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.

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.
