Abstract/Summary This paper provides an overview of the rationale of using bioaccessibility to predict arsenic bioavailability for risk assessment of rehabilitated mined land and its application to develop site-specific guidelines. The physiologically based extract test (PBET) in-vitro bioaccessibility model was used to assess of arsenic bioaccessibility and validated for its potential to predict bioavailability of mine wastes derived from rat in-vivo experiments. The alternative in-vitro approach, can replace animal in-vivo experiments, which simulate human uptake of arsenic. Comparison with bioaccessibility to predict bioavailability of arsenic then enables the development of a risk-based guideline approach for mine wastes.
