Two acute ecotoxicity studies were conducted on this PMN (P-11-0424) in (sponsor) with aquatic invertebrates and aquatic plants. The PMN is yellowish solid at room temperature with a purity of >97%, measured water solubility 4 g/L, a measured vapor pressure of 1.5E -5 mmHg at 25°C, and a measured log Kow of 3.6. The testing laboratory measured the PMN during the ecotoxicity studies using a HPLC-UV/Vis (limit of quantification (LOQ) = 0.03 mg/L and 0.075 mg/L for aquatic invertebrates and aquatic plants, respectively). The testing laboratory performed toxicity tests for the aquatic invertebrate and aquatic plant tests according to OECD guidelines 202 and 201, respectively. A certificate of analysis was provided for this PMN. The studies complied with OECD guidelines for: 1) O2, p H, temperature, water hardness values and other water quality parameters; 2) species, age, number of organisms per replicate, and biomass loading rates; and, 3) replicate and overall variability. In a 48-hour immobilization test, water fleas (Daphnia magna) (5 daphnia/replicate x 4 replicates) were exposed to nominal concentrations of 0.043, 0.094, 0.21, 0.45, and 1.0 mg/L (and a control) of the PMN under static conditions. The mean-measured concentrations were 0.013, 0.035, 0.054, 0.15, and 0.37 mg/L (and a control). Other than one immobile D. magna in the highest test concentration (statistically and biologically not significant), no effects were seen at all tested concentrations. Over the course of the study, water temperature ranged from 20-21°C; p H ranged fro m 7.

– 7.7; O2 levels concentrations ranged from 8.3-8.7 mg/L and water hardness was 250 mg CaCO3/L (in the dilution water). The measured 48-hour EC50 (immobilization) for D. magna is > 0.043 mg/L. The measured NOEC for immobilization is ≥ 0.043 mg/L. In a 72-hour limit test for algal growth rate and yield, an initial cell concentration of 0.5E+4 cells/ml (6 replicates/control and 3 replicates/test concentration) of green algae (Pseudokirchneriella subcapitata) were exposed to nominal concentrations of 0.010, 0.032, 0.10, and 1 mg/l (and a control) of the PMN under static conditions. The test concentrations resulted from dilutions from a 10 mg/L water accommodated fraction stock solution. The mean measured concentrations were: control, < LOQ, < LOQ, < LOQ, 0.06, and 0.21 mg/L. The test occurred with continuous light (640 lux) and continuous agitation. The temperature was 23°C. The pH ranged from 8.1

– 9.0. The water hardness was 24 mg CaCO3/L (in the dilution water). Cell growth was measured spectrophotometrically. The measured 72-hour algal EC50 for growth rate and yield are > 0.21 mg/L. The measured 72-hour algal NOEC for growth rate and yield are ≥ 0.21 mg/L. The two acute ecotoxicity studies are considered valid. Adverse effects were not observed in the

### daphnid and algal aquatic toxicity tests. There are no effects at saturation for aquatic invertebrates and aquatic plants for P-11-0424. Since only ecotoxicity tests for aquatic invertebrates and aquatic plants were submitted for P-11-0424, the chronic and acute concern concentrations for P-11-0424 will be based on the ECOSAR (v. 1.00a) p redictions for fish. As a result, the chronic and acute concern concentrations are 26 p pb an d 660 p pb, respectively. Ecotox Study Reviewer: J. Gallagher 15 June 2011
