Chronic Toxicity to Freshwater and Marine Fish (OPPTS Harmonized Guideline 850.1400; OECD Guideline 210) Conclusion: No available chronic toxicity data for freshwater and marine fish. Basis for Conclusion: No chronic toxicity studies in freshwater and marine fish were located. Chronic Toxicity to Freshwater Invertebrates (OPPTS Harmonized Guideline 850.1300; OECD 211) and Chronic Toxicity to Marine/Estuarine Invertebrates (OPPTS Harmonized Guideline 850.1350) Conclusion: No available chronic toxicity data for freshwater and marine/estuarine invertebrates. Basis for Conclusion: No chronic toxicity studies in freshwater and marine/estuarine invertebrates were located. Algal Toxicity (OPPTS Harmonized Guideline 850.5400; OECD Guideline 201) Conclusion: The available algal toxicity data were judged inadequate to meet the endpoint. Basis for Conclusion: The available data are summarized in Table 3-3. The summary of a 96-hour algal toxicity study (Unpublished study conducted in 1992, summarized in Akzo-Nobel, Inc., 2001a,b) indicates that the study does not meet the OPPTS Harmonized Guideline 850.5400. The pH and temperature of the test water during the study were outside of the acceptable ranges for Selenastrum capricornutum, as per Guideline 850.5400. Moreover, the two highest concentrations tested exceed the estimated water solubility of TDCPP (42 mg/L) and the concentrations tested were apparently not verified analytically. Additional information, including test substance purity, hardness, DO, TOC, TSS, exposure vessel size and head space, and measured chemical concentrations, were not provided in the summary. Also, there is no evidence that positive controls were used in order to establish that the algae were responding in the expected manner to a known chemical. The deviations from the OPPTS Guideline indicate that the study is inadequate to satisfy the algal toxicity endpoint. Another study indicates that TDCPP at 10 mg/L had no effect on growth or biomass of the algal species Scenedesmus subspicatus exposed for 72 3-36
hours (Unpublished study conducted by SafePharm, 1994, cited in IPCS, 1998). The study, or a study summary, was not available for the study by SafePharm (1994) to allow for an independent evaluation of these data. 3-37
