Abstract
This equilibrium partitioning sediment benchmark (ESB) document describes procedures to derive concentrations for 32 nonionic organic chemicals in sediment which are protective of the presence of freshwater and marine benthic organisms. The equilibrium partitioning (EqP) approach was chosen because it accounts for the varying biological availability of chemicals in different sediments and allows for the incorporation of the appropriate biological effects concentration. This provides for the derivation of benchmarks that are causally linked to the specific chemical, applicable across sediments, and appropriately protective of benthic organisms. EqP can be used to calculate ESBs for any toxicity endpoint for which there are water-only toxicity data; it is not limited to any single effect endpoint. For the purposes of this document, ESBs for 32 nonionic organic chemicals, including several low molecular weight aliphatic and aromatic compounds, pesticides, and phthalates, were derived using Final Chronic Values (FCV) from Water Quality Criteria (WQC) or Secondary Chronic Values (SCV) derived from existing toxicological data using the Great Lakes Water Quality Initiative (GLI) or narcosis theory approaches. These values are intended to be the concentration of each chemical in water that is protective of the presence of aquatic life. For nonionic organic chemicals demonstrating a narcotic mode of action, ESBs derived using the GLI approach specifically for freshwater organisms were assumed to also be protective of marine organisms. This assumption is based on the similar sensitivity of freshwater and marine organisms to narcotic chemicals like some of the nonionic organics in this document. For this reason, SCVs derived using narcosis theory are protective of both freshwater and marine organisms. For chemicals with more specific modes of action, freshwater and marine organisms were not assumed to be similar in sensitivity, and separate freshwater and marine ESBs were derived as the available data allowed. Because of the lack of a comprehensive toxicity data set and other reasons discussed in this document in detail, values derived here are considered Tier 2 ESBs (ESBTier2). The presentation of these ESBs is such that updated values could be calculated as new toxicity data become available.
