A method is described for measuring the in vitro bioaccessibility (IVBA) of arsenic in soil or soil-like media, and using the measured IVBA value to estimate the relative bioavailability (RBA) in swine or monkeys using empiric regression models developed from 20 (swine) or 17 (monkey) calibration soils. The correlation coefficients for the models are high (0.85 for swine, 0.87 for monkey), and the precision of the method is high, both within and between laboratories. This method is the most thoroughly tested, calibrated, and validated IVBA approach for estimation of arsenic RBA that has been described to date.
