DIN EN ISO 17402:2011-09

In this International Standard, requirements and guidance are given to select methods to assess bioavailability for different target species with regard to several classes of contaminants. Methods to assess bioavailability are not described in this guidance. Reference is made to existing International Standards and additional principles of measurement, which may need to be worked out in these International Standards. As only a few standards exist, reference is also made to measuring principles. Guidance is also provided for methods where promising first results for further standardization of a method are reported. The contaminants considered in this International Standard are metals, including metalloids, and organic contaminants, including organometal compounds and metals originating from natural geological and pedological processes (natural pedo-geochemical content).
