ACUTE TOXICITY TO AQUATIC INVERTEBRATES -- Ceriodaphnia dubia TEST SUBSTANCE Identity: N-Ethylperfluorooctanesulfonamide; may also be referred to as U1464, EtFOSA, EtPOSA, F-6309, or FX-12. (1Octanesulfonamide, 1,1,2.2,3,3.4,4,5,5.6,6,7,7.8.,8,8heptadecafuoro-N-ethyl-, CAS # 4151-50-2) Remarks: Material is a white solid. Sample purity and lot number were not recorded. METHOD Method: Adapted from OECD 202 -- Water accommodated fractions Type: Static acute GLP: No Year completed: 1998 Species: Ceriodaphnia dubia Analytical monitoring: Nominal concentrations only. Temperature, pH and dissolved oxygen recorded Statistical methods: : ELso (lethal loading) values were calculated using the probit method. The NOEL was calculated by Fisher's Exact Test, TOXSTAT Software Package, Version 3.5, Laramie, Wyoming. Test daphnid source:. AScl in-house culture, Duluth, MN Test daphnid age at study initiation: < 24-hour old neonates Test conditions: Dilution water: Carbon-treated dechlorinated City of Duluth, MN tap water aerated for 24-hours prior to use in the test. Dilution water chemistry during the study: Hardness 40-42 mg/L as CaCOs Do: 859.3 mglL Alkalinity: 42 mg/L as CaCO3 pH: 7.88.0 Conductivity 118-125 ymhos/cm Test Temp. Range: 21.2:21.3 Stock and test solution preparation: Test solutions prepared by mass addition of test substance to 1.5L aliquots of dilution water (one per concentration). The solutions were vigorously stirred (vortex 1/3 to % solution depth) for 20 hours. The aqueous phase was siphoned from the vessel at mid-depth. 006063 Exposure vessels: 30 mL borosilicate glass beakers Exposure volume: 20 mL Number of replicates: four Number of daphnids per replicate: five Number of concentrations: Five plus a negative control Element basis: mortality B-- ETS ------ Nominal loading concentrations: Bk control, 78, 130, 216, 360 and 600 moll Element value: 24-hour ELso: 380 (330-438) mg/L 48-hour ELso: 328 (278-391) mg/L 48-hour ELyg: 184 (130-224) mg/L 48-hour NOEL: 216 mg/L.

This study lacks analytical data for determination of the test substance concentration in the test solutions and determination of the sample purity. Testing was also done well above the solubility limit of the test substance with the use of water accommodated . fractions.
