ISO 8259:2024

This document specifies a method for testing the bioaccessibility of substances from contaminated soil and soil-like materials. The method is not applicable for volatile contaminants. Furthermore, the method is only applicable if suitable analytical methods for extraction and detection of substances and/or elements from complex digestion assays are available. NOTE          During the in vivo validation with minipigs, the PAHs naphthalene, acenaphthylene, acenaphthene and fluorene were not evaluated due to their volatility. However, the results of the overall recovery indicate if volatilisation has occurred during the test.
