Abstract

The physiologically-based extraction test (PBET) is being applied to soil from contaminated land sites to assess the environmental risk to humans. Various procedures have evolved based on the use of simulated gastric and intestinal juices. This chapter evaluates one approach to assess the environmental risk to humans from soil contaminated with metals. Soil samples have been obtained from contaminated sites in N.E. England with a historic legacy of pollution from heavy metals. Initial work will assess the total metal content of soils using microwave acid digestion followed by inductively coupled plasma mass spectrometry. A PBET test is evaluated and undertaken on the soils. The results highlight the additional, or supplementary information, provided by PBET and the role bioaccessibility data might play in a site specific risk assessment.
