Exceptions to GLP compliance: There were two study directors in this study. This study was designed as two separate studies. The in-life phase was considered to end at the generation and shipment of specimens. The analytical study was considered to start at the receipt of these specimens for analysis. This resulted in having two separate study directors, one for each phase of the same study. However, since the technical performance of each phase was entirely separate, no effect is expected from this exception. There is a lack of an electronic data audit trail. There is no reference standard stability. The surrogate THPFOS was not characterized.

The analytical phase of this study was initiated on 10 June 1999 (date of protocol signing). Test System Five groups of female pregnant rabbits (a total of 110 rabbits) were used as the test system for the main part of the study. Additional female pregnant rabbits (a total of 19 rabbits) were assigned to one of the same five dosage groups for the satellite study. It is only the satellite study that provided toxicokinetic samples that were tested and reported here. The test article, PFOS, was administered orally via a stomach tube once daily to female rabbits on days 7 through 20 of presumed gestation (DG7 through DG20). The carrier for the test article was 0.5% Tween 80 in Reverse Osmosis Membrane Processed Deionized Water. Doses of 0 (carrier only), 0.1, 1.0, 2.5 and 3.75 mg/kg/day were administered at a dosage volume of 5 mL/kg, adjusted daily on the basis of weight. The test system species and strain selected was the New Zealand White Rabbits [Hra:NZW)SPF)J received from Covance Research Products, Inc., permanently identified using a Monel self-piercing ear tag. F0 female rabbits were approximately 5 months of age and weighed approximately 2.84-4.21 kg when received. There were 133 female rabbits initially acclimated. The quantity actually used for the study is given in Table 1. The rabbits in the main portion of the study were sacrificed and a gross necropsy of maternal rabbit tissues and fetuses was performed. See the Argus Final Report #418-012 for results. Toxicokinetic samples for laboratory analysis at 3M Environmental Laboratory were only obtained from the satellite study portion. Table 1.

In addition, 18 fetuses and 18 placentas were collected on DG21 from sacrificed rabbits. One doe was not pregnant at the time of sacrifice; therefore, no fetuses or placenta were collected from this rabbit. The number and type of specimens collected for analyses in the analytical phase of this study are presented below. Specimens Collected from Satellite Study Groups 1 through 5 (through 9/10/98): Maternal Serum Specimens-- 19 specimens Maternal Liver Specimens-- 19 specimens Fetuses-- 18 specimens Placentas-- 18 specimens Blood specimens were collected and centrifuged. Serum was then harvested and frozen at -60C to -78C until shipped to the 3M Environmental Laboratory. Liver specimens collected from each animal were frozen and then stored at -60C to -78C until shipped to the 3M Environmental Laboratory. Fetuses and placentas were pooled per litter and stored frozen at -60C to -78C until shipped to the 3M Environmental Laboratory. Liver, sera, fetuses and placenta specimens were shipped to the 3M Environmental Laboratory frozen and on dry ice. (Note: Although fetal and placenta tissues were collected at the same time as liver and serum, results from these analyses will not be included in this report. A separate report may be issued for fetal tissue data.) Sera and liver samples were extracted beginning on 16 October 2000 using an ion pairing reagent and methyl-terf-butyl ether (MtBE). Liver samples were homogenized prior to the extraction procedure. Sample extracts were analyzed using high-pressure liquid chromatographyelectrospray/tandem mass spectrometry (HPLC-ES/MS/MS) in the multiple response mode. PFOS levels were quantitated by external calibration. Analytical details are included in this report. Specimen Receipt and Maintenance The 3M Environmental Laboratory received serum, liver, fetuses and placenta specimens collected at DG21 of the in-life phase of this study FACT TOX-099 on 15 September 1998 from Argus Research Laboratories. All specimens were received frozen on dry ice and were immediately transferred to storage at -20C 10C. Control matrices used in liver and sera analyses performed during TOX-099 were obtained from commercial sources and are presented in Appendix A (see Table 4). Samples analyzed at the 3M Environmental Laboratory will be maintained for a maximum period of 10 years and will be stored at the laboratory at -20C 10C. 3M Environmental Laboratory Page 9 3M Medical Department Study: T-6295.10 BACK TO MAIN Analytical Report: FACT TOX-099 LRN-U2400 Chemical Characterization of Reference Standard Potassium Perfluorooctanesulfonate (KPFOS) CAS Number: 2795-39-3 Chemical Formula: C8F17S 03'K+ Molecular Weight: 537.9 Chemical characterization information on the reference standard, potassium perfluorooctanesulfonate, CAS #2795-39-3, is presented in Table 2 below.

Detailed descriptions of the methods used in this study are located in Appendix C. As the present study progressed, more advanced methods evolved and earlier methods listed in the protocol were not used. Amendments to the protocol were written to cover method changes. These changes only improved the effectiveness of the method. Protocol, protocol amendments and deviations are included in Appendix B. 3M Environmental Laboratory Preparatory Methods ETS-8-4, "Extraction of Potassium Perfluorooctanesulfonate or other Fluorochemical Compounds from Serum for Analysis using HPLC-Electrospray/Mass Spectrometry" 3M Environmental Laboratory Page 10 BACK TO MAIN 3M Medical Department Study: T-6295.10 Analytical Report: FACTTOX-099 LRN-U2400 Serum samples were extracted using an ion-pairing extraction procedure. An ion-pairing reagent was added to the sample and the analyte ion pair was partitioned into MtBE. The MtBE extract was transferred to a centrifuge tube and put onto a nitrogen evaporator until dry. Each extract was reconstituted in 1.0 mL of methanol, then filtered with a 0.2 pm nylon filter attached to a 3 mL plastic syringe into glass autovials. ETS-8-6, "Extraction of Potassium Perfluorooctanesulfonate or Other Fluorochemical Compounds from Liver for Analysis Using HPLC-Electrospray/Mass Spectrometry" Liver samples were homogenized in water. An aliquot of each homogenate was spiked with THPFOS and extracted using an ion-pairing extraction procedure. An ion-pairing reagent was added to the sample and the analyte ion pair was partitioned into MtBE. The extract was transferred to a centrifuge tube and put onto a nitrogen evaporator until dry. Each extract was reconstituted in 1.0 mL of methanol and passed through a 0.2 pm nylon filter, using a 3 mL disposable plastic syringe, into glass autosampler vials. Analytical Methods ETS-8-5, "Analysis of Potassium Perfluorooctanesulfonate or Other Fluorochemicals in Serum Extracts Using HPLC-Electrospray/Mass Spectrometry" ETS-8-7, "Analysis of Potassium Perfluorooctanesulfonate or other Fluorochemicals in Liver Extracts Using HPLC-Electrospray/Mass Spectrometry" The analyses were performed by monitoring one or more product ions selected from a single primary ion characteristic of a particular fluorochemical using HPLC/ES/MS/MS. For example, molecular ion 499, selected as the primary ion for PFOS (C8F17S 0 3-) analysis, was fragmented to produce ion 99 (FS03-). The characteristic ion 99 was monitored for quantitative analysis. 3M Environmental Laboratory Page 11 BACK TO MAIN 3M Medical Department Study: T-6295.10 Analytical Report: FACT TOX-099 LRN-U2400 Analytical Equipment The analytical equipment settings used in the present analytical phase of this study varied slightly during data collection.

Amendments to the protocol were written to address method changes. Deviations from the original protocol and methods are included in Appendix B. Data Quality Objectives and Data Integrity The following data quality objectives (DQOs) were indicated in the protocol for this study: Linearity: The coefficient of determination (r2) equal to or greater than 0.98 Lim its o f Quantitation (LOQ): The LOQ is equal to the lowest acceptable standard in the calibration curve and is at least two times the analyte peak area detected in the extraction blanks. Acceptable Precision: Precision is better than 30% for the method Acceptable Spike Recoveries: 70-130% Confirm atory Methods: None. Demonstration of Specificity: Specificity to be demonstrated by chromatographic retention time and mass spectral daughter ion characterization. Data Summary, Analyses, and Results Data quality objectives for the analytical phase of this study outlined in the 3M Environmental Laboratory protocol for FACT TOX-099 (see Appendix B) were met with the exceptions noted in this report. Summary of Quality Control Analyses Results Linearity: The coefficient of determination (r2) of the standard curve was >0.98. Calibration Standards: Quantitation of PFOS was based on linear regression analysis (1/x weighted) of a single curve injected before or two extracted matrix curves bracketing, each group of samples. High or low points on the curve may have been deactivated to provide a better linear fit over the curve range most appropriate to the data. Low curve points with peak areas less than two times that of the extraction blanks were deactivated to disqualify a data range that may have been significantly affected by background levels of the analyte. Occasionally, a single mid-range curve point that was an obvious outlier may have been deactivated. Quantitation of PFOS* was based on the response of one specific product ion using the multiple response-monitoring mode of the instrument (see Appendix C, Analytical Methods). ` Isomers of P F O S were not chromatographically resolved. Quantitation was based on the sum of linear and all branched isomers. 3M Environmental Laboratory Page 13 3M Medical Department Study: T-6295.10 BACK TO MAIN Analytical Report: FACT TOX-099 LRN-U2400 Limits o f Quantitation (LOQ): The LOQ was equal to 0.00426 pg/mL and 0.0214 pg/mL in sera and 0.00529 (jg/g and 0.0529 |jg/g in liver. See Table 6 for LOQs on specific analytical dates. Blanks: All blanks were below the lower limit of quantitation for the compounds of interest. Precision: Precision was determined by triplicate analysis of one extracted liver sample injected three times and two sera samples that were reproducible to within 5%. Matrix Spikes: Matrix spikes and matrix spike duplicates were extracted with each set of samples and analyzed during analytical runs at the 3M Environmental Laboratory. Samples were spiked prior to extraction. Rabbit serum and liver samples for MS studies were obtained from commercial sources. After homogenation (liver) and prior to extraction, tissue samples were spiked with PFOS at approximately 250 ng/mL or 250 ng/g. All sera matrix spikes were within 10% of the theoretical concentration. Matrix spikes prepared in liver were compliant within 20% with one exception; one liver matrix spike was recovered at 156%. The average matrix spike recovery for the Group 1 samples was 138%. Surrogates: The surrogate (THPFOS) was added to all samples and standards prior to extraction. THPFOS was not used for quantitation, but was used to monitor for gross instrument failure. The surrogate response of each analytical run was monitored to determine that it did not vary more than 50% from the mean within each analytical run. No problems were observed with these data. Statem ent of Data Quality It is not possible to verify true recovery of endogenous analyte from tissues without radio-labeled reference material. The only measurement of accuracy available at this time, matrix spike studies, indicate that the data are quantitative to approximately 30%; values for liver analysis may be biased high. Summary of Sample Results (3M Environmental Laboratory) Samples from Control Animals: PFOS w as detected in the sera and liver o f all anim als. Samples from Dosed Animals: In general, PFOS levels found in the sera and liver of the test animals increased with dose group. PFOS levels increased as dosage increased. Detailed sample data tables are presented in Appendices D and E. Statistical Methods and Calculations Statistical methods were limited to the calculation of means and standard deviations. See Appendix F for example calculations used to generate the liver and serum sample data in FACT TOX-099. 3M Environmental Laboratory Page 14 3M Medical Department Study: T-6295.10 BACK TO MAIN Analytical Report: FACT TOX-099 LRN-U2400 Statement of Conclusion (3M Environmental Laboratory) Under the conditions of the present studies, the fluorochemical PFOS was observed in the liver and serum of all rabbits dosed with the test article during the in-life phase of the study.
