In vitro digestion and DGT techniques for estimating cadmium and lead bioavailability in contaminated soils: Influence of gastric juice pH

► Sensitivity analysis on an in vitro gastrointestinal digestion test. ► Influence of gastric juice pH on metal bioaccessibility, bioavailability, and health risk assessment. ► In vitro digestion and DGT techniques for estimating Cd and Pb bioavailability in contaminated soils. ► Inclusion of bioavailability analysis during health risk assessment opens a wide field of practical research.
