The Effect of Soil Properties on Metal Bioavailability: Field Scale Validation to Support Regulatory Acceptance

The technical objectives of the investigation were: (1) To provide validation that the relationships between soil properties and in vitro bio accessibility methods can serve as a screening tool for estimating in vivo toxic metal bioavailability in DoD soils; (2) To provide DoD with a scientifically...

Description
Summary:The technical objectives of the investigation were: (1) To provide validation that the relationships between soil properties and in vitro bio accessibility methods can serve as a screening tool for estimating in vivo toxic metal bioavailability in DoD soils; (2) To provide DoD with a scientifically and technically sound method for estimating human and ecological risk associated with metal contaminated soils in place of or as justification for more-detailed, site-specific bioavailability (e.g., animal dosing), and (3) to promote the use of in vitro methods in human health and ecological risk assessments through the upfront involvement of end-users and regulators and the subsequent dissemination of the results of the study in peer-reviewed journals.
