sources have 100% bioavailability when they are initially added to soil; for example, vitreous slags, tyre debris, massive metal, encapsulated materials, etc.

When total concentrations of contaminants are determined in a soil containing these materials, these contaminants will be solubilised, assumed to be bioavailable, and therefore some sites may exceed the EILs, yet the actual risk is negligible. Further chemical investigation of the bioavailability of the contaminants should be undertaken prior to direct toxicity assessment.

For a detailed review of methods to assess metal bioavailability in soils, see McLaughlin et al. (2000b). For detailed reviews of methods to assess bioavailability of organic contaminants in soils see Stokes et al. (2005) and Dean and Scott (2004).

Information on leachability tests applicable to contaminated sites can be found in Schedule B3.
