“…While we had insufficient data to determine the relative sensitivity of listed species of mussels in our dataset, we determined that unlisted mollusks are more sensitive to metallic stressors and nonpolar narcotics but less sensitive to OPs and neurotoxicants compared to other taxa. Others have proposed the use of daphnids and zooplankton as surrogates for freshwater mussels [13,67]. The data for listed mussels included in the present study support these conclusions: All four toxicity records for listed mussels exposed to metallic stressors were in the first quartile of their respective SSD, toxicity for mussels exposed to nonpolar narcotics were in the first and second quartiles, and toxicity of the listed mussel exposed to an OP was in the upper quartile.…”

A primary objective of threatened and endangered species conservation is to ensure that chemical contaminants and other stressors do not adversely affect listed species. Assessments of the ecological risks of chemical exposures to listed species often rely on the use of surrogate species, safety factors, and species sensitivity distributions (SSDs) of chemical toxicity; however, the protectiveness of these approaches can be uncertain. We comprehensively evaluated the protectiveness of SSD first and fifth percentile hazard concentrations (HC1, HC5) relative to the application of safety factors using 68 SSDs generated from 1,482 acute (lethal concentration of 50%, or LC50) toxicity records for 291 species, including 24 endangered species (20 fish, four mussels). The SSD HC5s and HCls were lower than 97 and 99.5% of all endangered species mean acute LC50s, respectively. The HC5s were significantly less than the concentrations derived from applying safety factors of 5 and 10 to rainbow trout (Oncorhynchus mykiss) toxicity data, and the HCls were generally lower than the concentrations derived from a safety factor of 100 applied to rainbow trout toxicity values. Comparison of relative sensitivity (SSD percentiles) of broad taxonomic groups showed that crustaceans were generally the most sensitive taxa and taxa sensitivity was related to chemical mechanism of action. Comparison of relative sensitivity of narrow fish taxonomic groups showed that standard test fish species were generally less sensitive than salmonids and listed fish. We recommend the use of SSDs as a distribution-based risk assessment approach that is generally protective of listed species.

“…First, the adequacy of CCCs, which were developed for protection of general aquatic life (USEPA, ; VDEQ, ), as protective levels for freshwater mussels has not been determined. Also, mussels are known to be sensitive to a variety of environmental metals, including Cd, Cu, Ni, Pb, and Zn (Havlik and Marking, ; Keller and Zam, ; Jacobson et al ., , ; Naimo, ; Keller et al ., ; Cope et al ., ; Wang et al ., ). In addition, other recent studies have found reasons for concern with metals as Clinch River water and sediment contaminants (Johnson et al ., ).…”

The Clinch River, in eastern United States, supports a diverse freshwater fauna including endangered mussels. Although mussel populations are stable in the Clinch's northeastern Tennessee segment, long-term declines have been documented upstream in Virginia. We analyzed water and sediment quality data collected by government agencies from the 1960s through 2013 in an effort to inform current management. The river was divided into sections considering data availability and major tributaries. We tested for spatial differences among river sections and for temporal trends, and compared measured values to potentially protective levels if available. Ammonia concentrations approaching and exceeding protective levels were recorded, most often during the 1970s and 1980s in upstream sections. Sediment metals occurred at levels potentially causing biological effects, mainly during the 1980s and 1990s. In the 2000s, water-column metals have been well below protective levels for general aquatic life. Dissolved solids (DS) increased in most river sections over the study period but mussel-specific protective levels are not known. Analysis of water pH, total N, and total P did not generate conservation concern. Enhanced monitoring for sediment metals, water-column metals, and ionic composition of DS; closer alignment of agency water monitoring practices in the two states; and research to determine biological effects of DS at current and anticipated levels can aid future conservation management.(KEY TERMS: rivers/streams; water quality; metals; nutrients; dissolved solids; freshwater mussels.)

“…More than 200 acute observations for glochidia and juveniles were identified from 10 sources [13][14][15][16][17][18][19][20][21] Utterbackia imbecillis was the only species for which we found 50% lethal (LC50) or effect (EC50) concentrations for both in vivo-and in vitro-produced juveniles. A total of 22, 96-h juvenile tests [13,15,18] were conducted, with 12 tests of in vitro-produced juveniles and 10 tests of in vivo-produced juveniles.…”

The state of Oklahoma has designated several areas as freshwater mussel sanctuaries in an attempt to provide freshwater mussel species a degree of protection and to facilitate their reproduction. We evaluated the protection afforded freshwater mussels by the U.S. Environmental Protection Agency (U.S. EPA) hardness‐based 1996 ambient copper water quality criteria, the 2007 U.S. EPA water quality criteria based on the biotic ligand model and the 2005 state of Oklahoma copper water quality standards. Both the criterion maximum concentration and criterion continuous concentration were evaluated. Published acute and chronic copper toxicity data that met American Society for Testing and Materials guidance for test acceptability were obtained for exposures conducted with glochidia or juvenile freshwater mussels. We tabulated toxicity data for glochidia and juveniles to calculate 20 species mean acute values for freshwater mussels. Generally, freshwater mussel species mean acute values were similar to those of the more sensitive species included in the U.S. EPA water quality derivation database. When added to the database of genus mean acute values used in deriving 1996 copper water quality criteria, 14 freshwater mussel genus mean acute values included 10 of the lowest 15 genus mean acute values, with three mussel species having the lowest values. Chronic exposure and sublethal effects freshwater mussel data available for four species and acute to chronic ratios were used to evaluate the criterion continuous concentration. On the basis of the freshwater mussel toxicity data used in this assessment, the hardness‐based 1996 U.S. EPA water quality criteria, the 2005 Oklahoma water quality standards, and the 2007 U.S. EPA water quality criteria based on the biotic ligand model might need to be revised to afford protection to freshwater mussels.
