Soil quality. Requirements and guidance for the selection and application of methods for the assessment of bioavailability of contaminants in soil and soil materials
This International Standard provides guidance for the selection and application of methods to assess
bioavailability for the characterisation of contaminated soil and soil materials. This International Standard does
not give a selection of the best applicable methods, but specifies boundary conditions and principles of
methods to be used and gives the minimal requirements for the development of methods. The results
obtained from such methods can be used as an estimate of bioavailability in a risk-assessment approach.
In this International Standard, when the term “soil” is only quoted for simplification, the broader term “soil and
soil material” shall be considered.
The contaminants considered in this International Standard are metals, including metalloids, and organic
contaminants, including organometal compounds. This International Standard is also applicable to metals
originating from natural geological and pedological processes (natural pedo-geochemical content).
This International Standard can also be applied to sediments.
NOTE An assessment procedure based on the bioavailable fraction of the total amount of contaminants in the soil or
soil material can contribute to the development of regulatory requirements of risk-based assessment procedures for soils.
According to the protection goals envisaged, applications of existing methods are recommended and their
limitations discussed, with the intention of promoting the development and introduction of workable standard
methods to be used in soil and site assessment. These methods are required to allow for the quantification of
factors influencing bioavailability.
