摘要
The bioavailability of cadmium, lead, and chromium leaching from soil was determined by an in vitro experiment utilizing artificial stomach and small intestine solutions. The dissolved concentrations of these metals in the model stomach + small intestine condition was lower than those found in the model stomach as a result of the re-adsorption to the soil by titration from pH 2.0 to 7.0.
