4 Background Information This workshop will focus on developing hypotheses/study designs to determine the cause of sediment toxicity to Eohaustorius estuarius in San Francisco Bay. It is expected that the products of this workshop will be applicable to other locations in California and the Pacific coast, as similar conditions are present in multiple embayments. We have assembled the following information to brief you on the current knowledge regarding the life history of E. estuarius, test protocol, contaminant sensitivity, sediment quality conditions in SF Bay, and prior efforts to determine the cause of toxicity to this species. The following documents are included: Sediment toxicity protocol fact sheet Background on the E. estuarius test method and sensitivity to contaminants and environmental factors. Appendix I provides a summary of standardized test conditions. Summary of amphipod sediment toxicity in San Francisco Bay Overview of past monitoring and assessment studies in San Francisco Bay. Supporting details are included in the attached paper (Anderson7a_SFSynthesis) TIE studies in California Summary of sediment TIE studies conducted in California bays and estuaries. Supporting details are described in a TIE study report for San Francisco Bay (Phillips9_TIEStudy). Sediment and water toxicity benchmarks (Appendix II) Tables of sediment and water effects levels for E. estuarius exposed to chemicals in sediment or water. Sediment chemistry and toxicity plots (Appendix III) Scatter plots of recent monitoring data (8-1) are provided to illustrate the sediment characteristics of San Francisco Bay sediments and associated E. estuarius toxicity test responses. Additional references cited in this background information will be available at the workshop and we will be happy to provide you with them upon request. 4
5 Sediment Toxicity Protocol Fact Sheet Eohaustorius estuarius Original Protocol A 1d amphipod test protocol using E. estuarius was evaluated by DeWitt et al. (DeWitt 1989) and found to meet many of the desired criteria for a sediment toxicity test for estuarine habitats. Standardized test guidelines were developed for this species by US EPA and ASTM (Appendix I). Protocol Guidelines U.S. EPA Methods for assessing the toxicity of sediment-associated contaminants with estuarine and marine amphipods (U.S. EPA 1994) ASTM.. Standard guide for conducting 1-day static sediment toxicity tests with marine and estuarine amphipods. (ASTM ) California protocol evaluations A rigorous comparison with other toxicity test species was conducted early in the Bay Protection and Toxic Cleanup Program (Hunt, Anderson et al. 1998; Hunt, Anderson et al. 1) and as part of the early San Francisco Estuary Regional Monitoring Program. Eohaustorius estuarius was the best performing laboratory test species for solid-phase testing, in addition to the bivalve development test conducted at the sediment-water interface. The Southern California Coastal Water Research Project (SCCWRP) also compared a number of test protocols as part the California State Water Resources Control Board s development of sediment quality objectives. Eohaustorius estuarius performed well in interlaboratory comparisons conducted under this program and was recommended as one of the preferred solid-phase test species for use in California (Greenstein, Bay et al. 8). Natural history Eohaustorius estuarius is a free burrowing sandy beach species that occupies intertidal to subtidal habitats along the west coast of North America from central California to British Columbia. It is considered to be a mesohaline species and has been shown to tolerate salinities from 2-28 (DeWitt 1989). Haustoriid amphipods are infaunal deposit feeders. Grain Size Tolerance Dewitt et al. (1989) assessed survival of E. estuarius in 42 uncontaminated field sediment samples from Puget Sound, Washington and Oregon. These authors reported that E. estuarius showed little sensitivity to sediments of different grain sizes: mean survival was 92.4% in sediments with >8% silt-clay content and 96.7% for coarser sediments. Environment Canada (1998) published grain size recommendations for the 1d test with E. estuarius. Based on un-published tolerance tests using commercial formulations of mixture of sand and clay. Tay et al. (1998) found mean survival was 74% in mixtures with 57% clay and 99% fines. Based on these experiments, they established tolerance limits of <9% coarse grained sediment, and less than 7% clay. The Environment Canada (1998) 1d guideline states that test materials with > 7% clay must not be used in a 1d sediment toxicity test with E. estuarius. 5
6 UC Davis conducted similar experiments using mixtures of sand and field-collected reference mud that was comprised of silt and clay. The field reference material was sieved through a 75 µm screen then mixed with sand to give sediments with 1 9% fines. E. estuarius 1d survival was >85% in sediments with <7% fines. Survival was 57% in sediment with 9% fines (Marine Pollution Studies Laboratory-Granite Canyon unpublished data). Eohaustorius estuarius Sensitivity to Chemicals Results of spiked water and/or spiked sediment toxicity tests suggest that E. estuarius is insensitive to metals relative to other amphipod species (Appendix II). For example, E. estuarius is not sensitive to copper (LC5 = 534 µg/g) or cadmium (LC5 = >1, µg/g) at concentrations typically measured in field sediments. Eohaustorius estuarius is relatively sensitive to certain classes of organic chemicals. For example, this species demonstrates comparable sensitivity to Hyalella azteca to current use pesticides, such as pyrethroids and organophosphates (e.g., chlorpyrifos). Eohaustorius estuarius are moderately sensitive to some organochlorine pesticides such as DDT, but not others, such as chlordane, and E. estuarius is moderately sensitivity to PAHs. 6
7 Summary of Amphipod Toxicity Test Results - San Francisco Estuary (Anderson, Hunt et al. 7) Seasonal effects Results have demonstrated greater toxicity in samples collected in winter months relative to summer months. Spatial Patterns Certain sites have demonstrated more consistent toxicity than others. Sites with the most consistent toxicity are usually located nears the margins of the estuary, and are proximate to estuarine tributaries such as creeks, rivers, and storm drains. Correlation studies Amphipod mortality in San Francisco Estuary sediments has been shown to correlate strongly with metals (e.g., Cu, Zn), organics (e.g., PAHs, chlordane), and mixtures of chemicals as expressed by an ERM Quotient value (ERMq) or Sediment Quality Guideline Quotient value (SQGQ1) (Thompson, Anderson et al. 1999; Hunt, Anderson et al. 1; Anderson, Hunt et al. 7; Phillips, Anderson et al. 9). All of these studies have also shown that amphipod mortality is strongly correlated with sediment grain size, particularly percent clay. Response relationships Scatter plots showing the association of E. estuarius survival with sediment characteristics are provided in Appendix III. These plots are based on randomly sampled stations from 8-1 regional monitoring studies in San Francisco Bay and are representative of the magnitude of concentrations and responses observed in the bay. Hotspot studies Studies in the mid-199s by the Bay Protection and Toxic Cleanup Program (BPTCP) identified several hotspots and reference sites in the San Francisco Estuary (Hunt, Anderson et al. 1998; Hunt, Anderson et al. 1; Hunt, Anderson et al. 1). All of the hotpots were located at the margins of the system at sites proximate to storm drains or adjacent to industrial chemical activities. Recent surveys have indicated that some of the hotspots remain toxic and contaminated (e.g., Mission Creek), while other former hotspots are now non-toxic and uncontaminated (e.g., Castro Cove). In addition, moderately high amphipod mortality has been observed at one of the former reference sites (Paradise Cove) identified by the BPTCP. These results suggest the Estuary remains a highly dynamic system, where deposition of uncontaminated sediment has reduced contamination at former hotspots such as Castro Cove, and where unknown stressors continue to affect amphipod survival at reference sites. 7
8 Toxicity Identification Evaluation (TIE) in California Sediment TIEs of samples from several California sites have indicated toxicity to E. estuarius is frequently due to pyrethroid pesticides. These include sediments from San Diego Harbor (Anderson, Phillips et al. 1), the Ballona Creek Estuary (Lao, Tsukada et al. 1), and upper Newport Bay (Anderson, Hunt et al. 7). A TIE of sediment from the Dominguez Channel in Long Beach Harbor suggested sediment toxicity was due to a mixture of organic chemicals which included high concentrations of PAHs (Anderson, Hunt et al. 7). TIE evidence from sites in the San Francisco Estuary has been less conclusive. A TIE of Mission Creek sediment suggested toxicity to E. estuarius was due to ammonia and mixtures of organic chemicals. The organic chemical mixture from Mission Creek was dominated by concentrations of organochlorine pesticides, especially chlordane. Subsequent dose-response experiments have shown that the chlordane concentrations in this sample were below the toxicity threshold for E. estuarius ([cis chlordane] = 29.8 ng/g; LC5 > 13,4 ng/g; [trans chlordane] = 35.5 ng/g; LC5 = >31,4 ng/g). Mission Creek sediment also contained approximately.63 toxic units of chlorpyrifos, as well as several PAHs. The copper concentration was 173 ug/g, which was equivalent to approximately one-third of a toxic unit (Phillips, Anderson et al. 9). A summary of chemical toxicity benchmarks for E. estuarius is provided in Appendix II. 8
