ACUTE TOXICITY TO AQUATIC INVERTEBRATES (DAPHNIA MAGNA) TEST SUBSTANCE Identity:Mixturecontainingperfluorooctanesulfonawtheich may alsobe referredto as PFOS, FC-95, or as a component of FC-3017. (1Octanesulfoniaccid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber was not noted. The testsample isFC-3017 produced inAntwerp, Belgium. CurrentinformationindicatesFC3017 isa mixtureof0.67% PFOS, 20% diethyleneglycolbutylether,55.41% water,21% ethyleneglycol,1.33% Hydroxy foamer, 1% sodium octylsulfate, 0.5% polyoxyethylenemonooctylphenylether,0.04% sodium laurylsulfate, and 0.05% tolyltraizole. The followingsummary applies to a mixture with incompletely characterizedconcentrations of impurities.Data may not accurately retlecttoxicityof the tluorochemical component of the testsample. METHOD: Method: OECD Guideline202 Type: Acute static GLP: No Year completed: 1995 Species: Daphnia magna Supplier:In-houseculturesm,aintainedatAScl-DETD, Duluth,MN Analyticalmonitoring:Temperature,pH, conductivitayn,d dissolved oxygen. Exposure period: 48-hours Test organism age: <24 hours old Statisticamlethods: LC50 values calculatedusing a computer program. Test conditions: Dilutionwater: DechlorinatedCityof Duluth,MN tap water post carbon filteare,ratedfor24 hours priorto use. Dilutionwater chemistry: Hardness: 50 mg/L as CaC03 Alkalinity: 46 mg/L as CaC03 Conductivity: 127 - 143 pmhos/cm pH: 7.82 TOC: 1.6mg/L Lighting:Cool-whitefluorescentlights.A dailyphotoperiodof 16 hours light and 8 hours darkwas maintainedthroughoutthetestingperiod. Stock and testsolutionpreparation: The testmaterialwas added directly tothe dilutiownater on a weight/volumebasisand mixed by mechanical stirrinagtambient labtemperature. Exposurevessels:250 mL beakerswith200 mL testsolution. Number of replicates4: Number ofdaphnids per replicate5: Number ofconcentrations:one plusa blankcontrol Water chemistryduringthe study: pH range (0-48hours): 7.9- 8.2(controelxposure) 7.8- 7.9(1000 mg/L exposure) Temperature range (0-48hours): 20.1 - 20.6 'C Conductivity range (0-48hours): 127 - 139 pmhos/cm (controelxposure) 142 - 143 pmhos/cm (1000 mg/L exposure) Dissolved oxygen range (0-48hours): 8.1 - 8.8 mg/L (controlexposure) 7.7- 8.9mg/L (1000 mg/L exposure) RESULTS Nominal concentrations:Blank controland 1000 mg/L. Element values: 24-hour EC50 = >1000mg/L 48-hour EC5o = >1000 mg/L 48-hour NOEC = 1000 mg/L Element values based on nominal concentrations. Remarks: Testingwas conducted on the mixtureas described inthe Test Substance Remarks field.The values reportedapply to thatmixtureand not the fluorochemicalproportionalone. CONCLUSIONS The testsubstance 48-hour EC50 was determined to be >1 000 mg/L. The 48hour No Observed EffectConcentration(NOEC) was 1000 mg/L. Submifter: 3M Company, EnvironmentalLaboratory,P.O. Box 33331, St. Paul,Minnesota, 55133 DATA QUALITY Reliability: Klimisch ranking = 2. This study meets the criteriafor quality testing.However, sample puritywas not properlycharacterizedand the study lacksanalyticaclonfirmationofthe amount of fluorochemicalproportionin solution.
