In vitro methods for the assessment of the oral bioaccessibility of selected metals and metalloids in soils: a review

Abstract

The article describes the laboratory methods for evaluating the oral bioaccessibility of metals and metalloids from contaminated soils (in vitro tests). These methods are based on the physiological characteristics of the gastrointestinal tract of humans. A comparison of ten methods. Methods PBET and SBET described in detail.
