/ N frU -0 5 2 .5 ACUTE TOXICITY TO FISH TEST SUBSTANCE_______________________________________________ Identity: Perfluorooctanoic acid, ammonium salt; may also be referred to as PFOA ammonium salt, Ammonium perfluorooctanoate, PFO, FC116, FC-126, FC-169, FC-143 or as the major component of FC1015. (Octanoic acid, pentadecafluoro-, ammonium salt, CAS # 3825-26-1) Remarks: The test sample is FC-1015. It's purity was not sufficiently characterized, though current information indicates is a 30% straight carbon chain version of FC-143 in 80% water. The 3M product lot number was "HOGE 205". The following summary applies to the test sample as a mixture of the test substance in water solution with incompletely characterized concentrations of impurities. Data may not accurately relate toxicity of the test sample with that of the test substance. Data was used to compare toxicity of the branched/straight chain ammonium perfluorooctanoate homologue mixture in FC-143 vs. what is supposed to be the 100% straight carbon chain ammonium perfluorooctanoate in FC-1015.

Test conditions: Dilution water: Deionized water adjusted to a hardness of 40 - 48 mg/L (as C a C 0 3) and passed through a particulate filter, ultraviolet sterilizer, and activated carbon. Dilution water chemistry: Hardness: 44 mg/L as C a C 0 3 Alkalinity: 29-30 mg/L as C a C 0 3 __, ^ 004049 TOC: <1 mg/L Lighting: Cool-white fluorescent lights at 30 foot-candles. A daily photoperiod of 16 hours light and 8 hours dark with a 15 minute transition period was maintained throughout the testing period. Stock and test solution preparation: Test solutions were created by direct individual weight additions. Concentrations dosing rate: Once Stability of the test chemical solutions: Not noted Exposure vessels: 20 L glass aquaria containing 15 liters test solution at an approximate depth of 18 cm. Number of replicates: two Number of fish per replicate: 20 Number of concentrations: five plus a blank control Water chemistry during the study: Conductivity range: (0-96 hours) 1 8 0 - 1 9 0 pmhos/cm (control exposure) 300 - 320 pmhos/cm (2100 mg/L exposure)* pH range (0-96 hours): 7.3 - 7.9 (control exposure) 7.2 - 7.7 (2100 mg/L exposure)* Temperature range (0-96 hours): 22.0 - 22.4 C (control exposure) 21.8 - 22.5 C (2100 mg/L exposure)* Dissolved oxygen range (0-96 hours): 5.8 - 9.2 mg/L (control exposure) 5.7 - 9.2 mg/L (2100 mg/L exposure)* * 2100 mg/L (second highest concentration) exposure values used because the highest concentration used resulted in total mortality at 72 hours. RESULTS________________________________________________________ Nominal concentrations: Bk control, 530, 830, 1330, 2100, and 3330 mg/L Element values: 96-hour LC50 = 2470 (2100 - 3330) mg/L 96-hour NOEC = 830 mg/L Element values based on nominal concentrations Remarks: Testing was conducted on the mixture of the test substance as described in the test substance remarks field.

SUXKARX The acuta toxicity of FC-1015 to tba fathead minnow. Pimaphalaa promelas, 1 described in this final report. The test was conducted for 3M Company for 96 hours from April 11 to IS, 1996, at T.R. Wilbury Laboratories, Ino. in Harblahead, Massachusetts. it was conducted by Jacqueline Nevlus, Jeanne Magazu, Xeven Stevens, Peter Kowalski, Robert Boeri, and Timothy Hard according to the procedures of the u.S. environmental Protection Agency (1993). PC-1015 was supplied by the sponsor. The test was performed under static conditions with five concentrations of test substance and a dilution water control at a temperature of 21.7 to 22.5*c. The dilution water was filtered deionized water collected at Marblehead, Massachusetts and adjusted to a hardness of 44 mg/L as CaCO^. Nominal concentrations of FC-1015 were 0 (control), S30, 830, 1,330, 2,100, and 3,330 mg/L. Fathead minnows used in the test were procured from a commercial supplier and acclimated to test conditions at T.R. Wilbury Laboratories. After 96 hours of exposure the control fieh had an average wet weight (blotted dry) of 0.36 g and an average total length of 35 mm. All fish were in good condition at the beginning of the study. Exposure of fathead minnows to FC-1015 resulted in a 96 hour median lethal concentration (LC50) of 2,470 mg/L, with a 95* confidence interval of 2,100 to 3,330 mg/L. The 96 hour no observed effect concentration (NOEC) is 830 mg/L.

METHODS AMD MATERIALS TEST SUBSTANCES The sample of FC-1015 (T.R. wilbury Laboratories Sample Humber 604) was delivered to T.R. wilbury Laboratories on April 4, 1996. The sample was delivered in a metal can within a cardboard box at ambient temperature. The test substance was contained in 1 250-ml plastic bottle. The label attached to the bottle contained the following informations "FC1015, (LR P1624), see MSDS, Susan A. Beach, 2-3E-09, (612) 778-7452, 4/2/96" . FC-1015 (a clear liquid) was supplied by 3M Company, St Paul, Minnesota. Prior to use the test substance was stored in the dark at room temperature. The test substance was assumed to have a purity of 100% 'active ingredient and to be stable under storage and testing conditions. Unused test substance is returned to the sponsor. DILUTION MATER I Water used for acclimation of test organisms and for all toxicity 3,4. .tasting was deionized water collected at T.R. Wilbury Laboratories in Marblehead, Massachusetts. Water was adjusted to a hardness of 40-48 mg/L :as CaCO, and stored in 500-gallon polyethylene tanks where it was aerated iand continuously passed through a particle filter, ultraviolet sterilizer, iand activated carbon, water used for the test had a hardness of 44 mg/L, I'iwd acidity of 24 mg/L and an alkalinity of 29-30 mg/L as CaCO,, and it contained'<10 mg/L particulate matter and <1 mg/L:total-organic; carbon.

Tha apaciaa of tha fiah waa verified ualng an appropriate taxonomic key. Prior to taating tha fiah vara maintained under flow through eonditione in a 270 liter fiberglaaa tank. During acclimation fiah vara not treated for dieeaae, and they rare free of apparent sickness, injuriaa, and abnornalitiea at the beginning of the teat. Mortality during the final 48 houra of acclimation vaa leaa than 3t. During the 14 day period before the start of the test the acclimation temperature range was 22.0 to 22.9*c and the dissolved oxygen concentration was always at least 7.6 mg/L. During acclimation fish were fad a dry commercial food (Tetra Min* staple rood. Lot t TM06) daily except during the 48 houra immediately preceding the teat, riah were not fed during the test. At the conclusion of the test the control fish had an average total length of 35 mm and an average wet weight of 0.36 g (loading during the toxicity teat was 0.24 g/L). TOXICITY TESTING I The toxicity test waa performed according to the procedures of the u . s . Environmental Protection Agency (1993). A summary of the test system ia presented in Table 2. A screening test was not conducted because nominal concentrations for the definitive teat were provided by the sponsor. The definitive teat was performed from April 11 to 15, 1996 with five concentrations of teat substance and a dilution water control. Nominal concentrations of p c-101 5 were 5 3 0 , 830, 1 ,3 3 0 , 2 ,1 0 0 , and 3 ,3 3 0 mg/L. Appropriate amounts of test substance were added directly to dilution water in test vessels without the use of a solvent., i . i ........ ,.->.5, ml. Twenty fathead minnows were indiscriminately and equally distributed among two replicates of each treatment. The teat was performed in 20 liter glass aquaria that contained 15 liters of test solution (water depth waa approximately 18 cm). Test vessels were randomly arranged in a water bath during' the ,96 ;hour :test (a:-random numbers table was used to select the location'of.;-each vessel) and they were loosely covered. `'.The test was conducted at 22 t 2*C. A 16 hour light and 8 hour dark photoperiod 'with' a '15'- minute', transition period was automatically 1maintained withicool-white^fluorescent lights that provided a light intensity of, 30 footcandles. `r :<1 1 > 1 tFIeTiqrIv*.
