Appendix to Bioaccumulation Testing and Interpretation for the Purpose of Sediment Quality Assessment: Status and Needs - Chemical-Specific Summary Tables

The document is an appendix to Bioaccumulation Testing and Interpretation for the Purpose of Sediment Quality Assessment: Status and Needs. It summarizes information on chemical characteristics, including water solubilities, half-lives, and partition coefficients (log Kow and Log Koc); human health concerns; wildlife and aquatic organism partitioning factors; and food chain multipliers. A brief profile of the chemical's toxicity, mode of action, and potential for bioaccumulation is also included. Daily intake levels of concern for the protection of human health were compiled, including estimated values for carcinogenic endpoints (slope factors) and noncarcinogenic endpoints (reference doses) for the oral ingestion exposure pathway, and EPA's carcinogenic classifications are provided. Factors affecting partitioning of the chemical in relation to wildlife and aquatic organisms, food chain multipliers (biomagnification factors), toxic effects and mode of action, and other information were compiled from various sources. Data in the chemical summary tables will be useful in addressing the following issues pertaining to bioaccumulation: What species are potentially available for testing?; How should we account for differential partitioning of bioaccumulative contaminants among tissues?; How can bioaccumulation methods be used to assess population-level effects?; How can tissue-specific residue levels be coupled with chronic toxicity response data to develop dose-response relationships for bioaccumulative contaminants?
