Study Reference Species Tested Ref. 46 Killifish (Oryzias latipes) Goldfish (Carassius auratus) 96-Hour LC 50 Killifish: 3.6 mg/L Goldfish: 5.1 mg/L Table 4-1. Summary of available acute fish toxicity studies for Proprietary A a Study Type Concentrations Tested Selected Study Design Parameters b No. of Fish/ Conc Static NR 7 to 9 Unclear if conducted Analytical Monitoring Water Chemistry Solvent pH: NR Temp: 25°C. DO: NR Hardness: NR Electrical conductivity: NR a Studies that were either published in a foreign language or that were not readily and that were not critical to the hazard assessment were not retrieved. bNR: Not reported 4-33 Comments on the Data NR Fish were acclimated at least for 10 days at 25 °C. The test concentrations used were not reported. A control group was not tested. Killifish, but not goldfish, are a designated test species, as per OPPTS 850.1075 (Fish Acute Toxicity Test, Freshwater and Marine). Deformation of the spine was observed in 7/10 killifish exposed to 3.5 mg/L Proprietary A for 24 hours.
Acute Toxicity to Freshwater Invertebrates (OPPTS Harmonized Guideline 850.1010; OECD 202) Conclusion: The acute toxicity data for freshwater invertebrates were judged inadequate to meet the endpoint. However, if the results of the study cited by Ref. 29 (see below) are confirmed independently, the endpoint might be satisfied given the high degree of agreement of the two available studies in freshwater invertebrates. Basis for Conclusion: The available data are summarized in Table 4-2. A flow-through study revealed a 48-hour LC 50 of Proprietary A with Daphnia magna of 3.8 mg/L (95% CI: 3.5-4.2 mg/L) and a NOEC of 1.6 mg/L (Unpublished study conducted in 1999, summarized in Ref. 4, 5). Although some of the conditions of the study design (such as number of organisms, and water temperature and chemistry) appear to meet OPPTS Harmonized Guideline 850.1010, other aspects of the study, including compound purity and condition and fertility of the organisms in culture, were not reported in the summary. The amount of solvent used in the control group and the Proprietary A treatments might have exceeded the recommended maximum solvent concentration, as per the OPPTS Guideline (100 mg/L), but this does not appear to have affected the study results. A 48hour LC 50 of 4.6 mg/L and a NOEC of 1.8 mg/L were reported for daphnia in a study by Ref. 43, as cited in Ref. 29. Although the results of the study by Ref. 43 are in agreement with those of Ref. 4, 5, the study by Ref. 43, or a study summary, was not available to allow for an independent evaluation of these data. Confirmation of the results of the study by Ref. 43 might allow the acute freshwater invertebrate toxicity endpoint to be satisfied. Acute Toxicity to Marine/Estuarine Invertebrates (OPPTS Harmonized Guideline 850.1035) Conclusion: No available acute marine/estuarine invertebrate toxicity data. Basis for Conclusion: No acute toxicity studies in marine/estuarine invertebrate species were located. 4-34
