The book also illustrates how bioavailability adjustments can be incorporated into risk assessments to generate risk-based cleanup values that are more site specific than those based on the default assumption of complete bioavailability. Although the book focuses on oral bioavailability of metals to human receptors, many of the basic principles described herein also can be applied to assessing bioavailability of organic compounds and for assessing bioavailability to ecological receptors."--BOOK JACKET.

Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

The Phase II objective was to provide information on the role of bioavailability in evaluating human exposures to chemicals in soil and how this scientific information can be used to enhance risk assessment and remediation decisions at soil-sites. The BPP Working Group formed a Metals Task Force and an Organics Task Force to help focus on timely developments in basic and applied science and regulatory policies for each chemical group. Emphasis was placed on providing a greater context for understanding and using bioavailability in assessing human health risks and potential remedies, as well as identifying information needs for future decision-making. Each Task Force developed similar areas for investigation and study, which are as follows: Relative Bioavailability and Risk Determination; Methods for Assessing Bioavailability from Soils; Assessment of Current Scientific Knowledge; Future Research Needs; Regulatory Policies; Case Studies; Conclusions and Future Dire.

Total Petroleum Hydrocarbon (TPH) contamination of soil is a problem at Air Force bases nationwide, causing it to be a major environmental clean-up concern. Human exposure to TPH in the soil can occur through several pathways, including ingestion of soil or sediment particles. Exposure through ingestion of TPH contaminated soils can be investigated using oral soil dosing studies. This technical report focuses on the methods used in soil dosing studies, the effects of soil on the bioavailability or toxicity of contaminants, and the potential use of bioavailability information in risk assessments and the development of risk-based clean-up sites.
