It'psuritywas notsufficiently characterizedt,hough currentinformationindicatesisa 30% straighctarbon chain versionofFC-143-in80% water. The 3M productlotnumber was "HOGF--205". The following summary applies to the testsample as a mixture of the 'testsubstance in water solution with Incompletely characterized concentrations of Impurities. Data may not accurately relatetoxicityof the testsample with that of the testsubstance. Data was used to compare toxicityof the branchedlstraight chain ammonium petfluorooctanoate homologue mixture In FC-143 vs. what Is supposed to be the 10001ostraightcarbon chain ammonium perfluorooctanoate In FC-1015.

The objective of the study was to determine the 24, 4B, 72, and 96 hour median lethal concentrations (LC509) of the test substance to the fathead minnow, Pimophal*s promolafir a freshwater fish, under static conditions. The study was conducted following U.S. EPA (TSCA) guidelines but at the Sponsor's request it was not conducted according to Good Laboratory Pzar-tice (GLP) rules.

METHODS AlrD XJLTR-RIALS TEST SUBSTANCET The sample of FC-1015 (T.R. wilbliryLaboratories Sample Number 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 information; -rc1015, (LR P1624), see MSOS, 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 WA=RI Water'used for acclimation of test organisms and for all toxicity 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 and continuously passed through a particle filter, ultraviolet sterilizer, .,activatedcarbon.

The species of the fish was verified using an appropriate taxonomic key. Prior to testing the fish were maintained under flow through conditions in a 270 liter fiberglass tank. During acclimation fish were not treated for disease, and they were fro* of apparent sickness, injuries, and abnormalities at tha beginning of the test. mor-tality during the final 48 hours of acclimation was less than 3%. During the 14 day period before the start of the test the acclimationtemperaturerange was 22.0 to 22.9*C and the dissolvedoxygen concentration was always at least 7.6 mg/L. During acclimationfish were fed a dry commercial food (Tetra Kin* Staple Food, Lot # 'rM06)daily except during the 48 hours immediately preceding the test. Fish were not fed during the test. At the conclusion of the teat the control fish had an average total length of 35 = and an average vot weight of 0.36 9 (loading during the toxicity test was 0.24 g/L). TOXICIT'Y TESTING: The toxicity test wan performed according to the procedures of the U.S. Env4.ro=ental Protection Agency (1993). A summary of the test system is presented in Table 2. A screening test was not conducted because nc=Linal concentrations for the definitive test were provided by the sponsor. The definiti-.,teebt was performed from April 11 to 15, 1996 with five concentrations of test substance and a dilution water control. Nominal concentrations of FC-1015 were 530, 830, 1,330, 2,100, and 3,330 mg/L. Appropriate amounts of test substance were added directly to dilution water in test vessels without the use of a solvent. Twenty fatboad minnows were indiscriminately among two replicates of each treatment. The 20 liter glass aquaria that contained 15 liters and equally distributed test was performed in of test solution (water depth water was approximately 18 cm) . Test vessels were randomly arranged in a bath during the-,96 hour,"iest (a random numbers table was used to select the location'of, each 'vessel) and they were loosely covered. --@The to at was conduct. at, 22.t 2 C.@,JL I 6 hour light and 8 ho ur dar)@@ '@@'@photoperiod .-@@'maintained ' with',-;i'-15-'@ z@inuis@t@-transition'.. period with "c@ool@'-whitit'.f@lu@@oisconIE- lights, that was automatically provided a ligh -@zintensity, of @30,'fcot@@dl 'a-.

STATISTICJLL MZTEODS: Re ults' of -:the toxicity test were inter-proted by standard statistiIcal toohniques. co=puter methods (Stephan, 1983) were used to calculate the median lethal concentrations (LC50s). )Lllcalculations were performed using nominal concentrations cf test substance and the number of live fathoad minnows. The no observed effect concentration is the highest' concentra tion of test substance that did not cause any toxicant-related mortality or sublethal effects. y Btu y N 1031-@TH di 10.of 19 Vil.

The measured concentrations of dissolved oxygen ranged from 5.6 to 9.2 mg/L, the temperature ranged from 21.7 to 22.5*C, conductivity ranged from 180 to 390 pmhoo/cm, and pH ranged from 7.2 to 7.9. one hundred percent survival occurred in the control exposure and these fathead minnows did not exhibit any sublethal offects. The 2 48, 72, and 96 hour LCSOs for fathead minnows exposed to rc 1015 are presented in Table 4. The 96 hour LC50 for fathead minnows exposed to FC-1015 is 2,470 mg/L, with a 95% confidence interval of 2, 100 to 3,330 m4/L, The slope of the 96 hour dose response cur-ve is 10.
