Formatted Abstract/Summary Oral exposure is a significant exposure pathway for metals and metalloids present in contaminated material. Traditional risk assessment protocols assuming 100 % bioavailability may over-estimate and lead to expensive remediation for contaminated sites. A simple cost-effective and less time consuming in vitro extraction technique such as the physiologically-based extraction technique (PBET) was employed to predict the bioavailability of inorganic arsenic from tailings and contaminated creeks and river sediments collected from the Vatukoula/Tavua region of Fiji by simulating the human gastrointestinal (GI) tract.

X-ray absorption spectroscopy is a superior tool for measuring arsenic speciation to better understand its relationship with bioavailability.
