The approach, based on procedures described in U.S. EPA (2003), involves the use of equilibrium partitioning techniques to determine exposure/bioavailability and narcosis theory to estimate sublethal toxicity of PAHs. Examples of how to use this approach with analytical data resulting from the analysis of contaminated sediments are provided. Additionally, this approach offers risk assessors a useful tool for assessing the risk of PAHs to benthic invertebrates at hazardous waste sites, particularly when used with other contaminated sediment assessment methods.
