Acute Toxicity to Freshwater and Marine/Estuary Invertebrates (OPPTS Harmonized Guidelines 850.1010 and 850.1035; OECD Guideline 202) Conclusion: • The available acute freshwater invertebrate toxicity data were judged adequate to meet the endpoint. • The available acute marine/estuary invertebrate toxicity data were judged inadequate to meet the endpoint. • Based on the environmental fate of TPP, additional data may be needed on sediment dwelling organisms. Currently available studies, although inadequate to meet the endpoint in this review, indicate that TPP may be toxic to sediment-dwelling organisms. Basis for Conclusion: Freshwater Organisms The available data are summarized in Table 1-2. Four studies in daphnids were located. All studies used static conditions, and none of the available studies analytically confirmed the test concentrations. The reported EC50 values were consistent with each other and ranged from 1,000 to 1,350 :g/L. Sufficient detail was available from three of the four studies located to allow for an independent evaluation of data adequacy. Reporting deficiencies were noted in those three studies that included lack of identity of concentrations tested, TPP purity, concentration of solvent in the test solutions, and water hardness. In the remaining study (Ziegenfuss et al., 1986), even basic study design parameters were not reported. Due to these reporting deficiencies and on study design deficiencies (lack of analytical confirmation of the test concentrations), none of the currently available studies are independently sufficient to be used as the basis to satisfy the acute freshwater invertebrate toxicity endpoint. Collectively, however, the data appear adequate because the four studies that were located reported a narrow range of EC50 values, thus providing confidence in the reported effect levels. Studies were also located on the toxicity of sediment-dwelling organisms. Two studies using the midge and one study using the scud were located. These studies indicate that sediment-dwelling organisms could be particularly sensitive to the toxicity of TPP. EC50 values ranged from 250 to 1,600 :g/L. All of the studies in sediment-dwelling organisms used static conditions, and none of the studies analytically confirmed the test concentrations. Based on the inconsistencies in the reported toxicity values and the lack of a study that analytically confirmed the test substance concentrations, these data were not judged to be adequate to satisfy the acute toxicity endpoint for sediment-dwelling organisms. Based on the environmental fate of TPP, additional testing on sediment-dwelling organisms may be needed. In addition, a confidential study for acute toxicity to freshwater aquatic invertebrates was submitted for which study results were consistent (daphnid 48-hour LC50 = 1.2 mg/L) with 1-34
those reported in the publicly available literature. The available data were judged adequate to meet this endpoint. Marine/Estuarine Organisms One acute toxicity study in mysid shrimp was located (Table 1-2). The study was a 96-hour static study that did not analytically confirm the test concentrations. The dissolved oxygen concentration in this study was
