Short description: Studies of bioavailability are of great interest with respect to definition of realistic soil quality criteria and remedial targets. In this review study, various methods and data are evaluated as no standard methods are as yet defined. 
Long description: Bioavailability of soil contaminants depends on the ability of the contaminants to dissolve in the fluids in human stomach and small intestine and be absorbed by the intestinal membranes. The solubility of the contaminants in the gastrointestinal system depends on soil type, source and age Different in-vitro methods give varied results, but several methods are recommended in this study. Reduced soil bioaccessibilty is very likely for cadmium, lead and chromium(III) and likely for arsenic and chromium (VI) and possibly for copper, nickel, zinc and PAH. Studies of bioaccessibility are most suitable for site specific remediation, but as yet are not suitable for general regulation of soil quality criteria and clean-up levels.
