(Centre) extracted mallard liver samples and mallard serum samples for the determination of perfluorooctanesulfonate (PFOS) in mallard serum and mallard liver according to protocol 00P-023-042 (Appendix A). The limit of quantitation for mallard liver was 10 ppb and 10 ng/mL for mallard serum. The LOQ for each matrix was determined in a method verification study performed at Centre (Centre Study: 023-044). Residues of PFOS in the mallard liver samples ranged from non-quantifiable levels (a peak was detected at the corresponding analyte retention time but was less than the lowest concentration of the calibration standards (0.0001 pg/mL)) to 22.8 pg/g. These results are reported on a wet weight basis. PFOS in the mallard serum samples ranged from non-quantifiable levels to 218 pg/g. The average percent recovery standard deviation for PFOS in liver samples was 95% 12%. The average percent recovery + standard deviation for PFOS in serum samples was 93% 10%. 2.0 OBJECTIVE The objective of this study was to determine levels of perfluorooctanesulfonate (PFOS) in specimens of mallard liver and mallard serum using the analytical methods described in protocol 00P-023-042. 3.0 INTRODUCTION This report details the results of the analysis for the determination of PFOS in mallard liver and mallard serum, using the analytical methods entitled, "Extraction of Potassium Perfluorooctanesulfonate or Other Fluorochemical Compounds From Liver for Analysis Using HPLC-Electrospray/Mass Spectrometry" and "Extraction of Potassium Perfluorooctanesulfonate or Other Fluorochemical Compounds From Serum for Analysis Using HPLC-Electrospray/Mass Spectrometry". The study was initiated on November 10, 2000, when the study director signed Centre protocol number 00P-023-042. The experimental start date was November 17, 2000, and the experimental termination date was March 13,2001. Centre Analytical Laboratories, Inc. Page 12 of 104 Centre Study No.: 023-042 4.0 TEST SYSTEM The control mallard liver and serum used for the matrix blanks and matrix fortifications was received on May 18, 2000 from Wildlife International Ltd., Easton, MD. The control mallard liver was assigned the Centre ID of 0003804 and the control mallard serum was assigned the Centre ID of 0003803. Sixty mallard liver samples and sixty mallard serum samples were received at Centre on August 10, 2000. The samples were stored frozen until they were logged in by Centre personnel on August 16, 2000 and stored frozen. An additional twenty mallard liver samples and forty mallard serum samples were received on February 24, 2001 and stored frozen until they were logged in by Centre personnel on March 1, 2001. Sample log-in and chain of custody information can be found in the raw data package associated with this study.

Centre Analytical Laboratories, Inc. Page 13 of 104 Centre Study No.: 023-042 6,0 DESCRIPTION OF ANALYTICAL METHOD Analytical methods entitled "Extraction of Potassium Perfluorooctanesulfonate or Other Fluorochemical Compounds From Liver for Analysis Using HPLC-Electrospray/Mass Spectrometry" and "Extraction of Potassium Perfluorooctanesulfonate or Other Fluorochemical Compounds From Serum for Analysis Using HPLC-Electrospray/Mass Spectrometry" were used for this study. 6.1 Extraction Procedure A ~ 0.50 g sample of liver and a 100 pL aliquot of the serum was used for the extraction procedure. After fortification of appropriate samples, the samples were vortexed for ~ 15 seconds. One milliliter of 0.5 M TBA was added to the liver samples and 0.5 milliliter was added to the serum samples. Two milliliters of 0.25 M sodium carbonate/sodium bicarbonate was added to the liver samples and 1 milliliter was added to the serum samples. Five milliliters of MTBE was added to both the liver and serum samples. Each sample was placed on wrist-action shaker for ~ 20 min. and then centrifuged for ~ 15 min. Four milliliters of the organic layer was taken and dried on a nitrogen evaporator and then reconstituted with 1 milliliter of methanol. Each sample was analyzed by LC/MS/MS electrospray. 6.2 Preparation of Standards and Fortification Solutions Standard solutions were prepared on September 18, 2000 as specified in Centre Analytical Laboratories' protocol 00P-023-042. An individual stock standard solution of PFOS was prepared at a concentration of 100 pg/mL by dissolving 10 mg of the standard (corrected for purity and salt content) in methanol. From this solution, a 1.0 pg/mL fortification standard solution was prepared by taking 1 mL of the stock and bringing the volume up to 100 mL with methanol. A 0.1 pg/mL fortification standard was prepared by taking 10 mL of the 1.0 pg/mL fortification standard and bringing the volume up to 100 mL with methanol. A 0.01 pg/mL standard was prepared by taking 10 mL of the 0.1 pg/mL standard and bringing to 100 mL with methanol. A set of standards containing PFOS was prepared by serial dilution of the 0.1 pg/mL and 0.01 pg/mL solutions in the following manner: Initial Cone. (pg/mL)1 Volume (mL) 0.1 5 0.1 2 0.1 1 0.01 5 0.01 2 0.01 1 1of PFOS Diluted to (mL) 100 100 100 100 100 100 Final Cone.

Documentation of standard preparation can be found in the raw data associated with this report. 6.3 Chromatography Quantification of PFOS was accomplished by LC/MS/MS electrospray. The retention time of PFOS was ~ 4.4 min. Peaks were detected in the control matrices corresponding to the analyte retention time, but the amounts detected were only significant enough to alter several fortification recoveries and the rest were less than the lowest calibration standard (0.0001 pg/mL). 6.4 Instrument Sensitivity The smallest standard amount injected during the chromatographic run had a concentration of 0.0001 pg/mL of PFOS. 6.5 Description of Instrument and Operating Conditions Instrument: PE SCIEX API 3000 Biomolecular Mass Analyzer Interface: SCIEX Turboion Spray Liquid Introduction Interface Computer: Dell UltraScan P1110 Software: HPLC: PE SciexAnalyst version 1.1 Windows NT, version 4 H ewlett Packard (HP) Series 1100 HP Quat Pump HP Vacuum Degasser HP Autosampler HP Column Oven HPLC Column:Genesis Cg (Jones Chromatography), 2.1 mm x 50 mm, 4p Column Temp.: 35 C Injection Voi.: 10 pL Mobile Phase (A): 2 mM Ammonium Acetate in ASTM type I water Mobile Phase (B): Methanol Flow Rate: 0.3 mL/min.

The peak area was measured and the standard curve was generated (using 1/x fit weighted linear regression) by Analyst software using six concentrations of standards. The concentration for mallard liver (pg/g) and mallard serum (pg/mL) was determined from the equations below. Equation 1 calculated the amount of analyte found (in ng/mL, based on peak area) using the standard curve (linear regression parameters) generated by the Analyst software program. Then Equation 2 calculated the amount of analyte found in pg/mL (the equations for serum are shown). Centre Analytical Laboratories, Inc. Page 16 of 104 Centre Study No.: 023-042 Equation 1: Analyte found (ng/mL) = (Peak area - intercept) slope Equation 2: Analyte found (pg/mL) = ((anal, found (ng/mL) x FV (mL) x DF x EV (mL)) x 1 pg (AV (mL) x sample vol. (mL)) 1000 ng Where: FV = Final Volume DF = Dilution Factor EV = Extraction Volume AV = Aliquot Volume For samples fortified with known amounts of PFOS prior to extraction, Equation 3 calculated the percent recovery. Equation 3: Recovery (%) == ((anal, found (pg/mL) - avg. anal, in Ctrl (pg/mL)) x (1000 ng/1 pg)) x 100___ amount added (ng/mL) An example of a calculation using an actual sample follows: Mallard serum sample Centre ID 0003803 Spk A (Set: 112100B), fortified at 10 ng/mL with PFOS, where: peak area 6558 intercept 515 slope 7740 dilution factor 1 ng added (fort level) 1ng avg. amt in controls 0 (N ot quantifiable) final volume 1 mL extraction volume 5 mL aliquot volume 4 mL sample weight (volume) 0.1 mL From equation 1: Analyte found (ng/mL) = f6558- 5151 7740 From equation 2: Analyte found (pg/mL) 0.8 ng/mL = (0,8 ng/mL x 1 mL x 1 x 5 mL) x 1 ug (4mLx0.1mL) 1000 ng = 0.00976 pg/mL Centre Analytical Laboratories, Inc.

Each sample was extracted using the appropriate method and then analyzed in duplicate. 8.0 RESULTS The PFOS found in the reagent blanks are listed in Table I. The PFOS in the mallard liver blanks and mallard serum blanks are given in Tables II & III. Individual recoveries for PFOS in the liver samples are detailed in Table IV. The average percent recovery standard deviation for PFOS in liver samples was 95% 12%. Individual recoveries for PFOS in the serum samples are detailed in Table V. The average percent recovery relative standard deviation for PFOS in serum samples was 93% 10%. PFOS in the mallard liver samples ranged from non-quantifiable levels (a peak was detected at the corresponding analyte retention time but was less than the lowest concentration of the calibration standards (0.0001 pg/mL)) to 22.8 pg/g. Individual results are listed in Tables VI-XIII. The results are reported on a wet weight basis. PFOS in the mallard serum samples ranged from non-quantifiable levels (a peak was detected at the corresponding analyte retention time but was less than the lowest concentration of the calibration standards (0.0001 pg/mL)) to 218 pg/g. Individual results are listed in Tables XIV-XXIII. The percent moistures for the mallard liver samples are given in Table XXIV. 9.0 CONCLUSIONS The mallard liver and serum samples were successfully extracted and analyzed according to protocol 00P-023-042.

JUSTIFICATION FOR THE SELECTION OF THE TEST SYSTEM Mallard serum samples and liver samples collected by Wildlife International, Ltd. will be used as the test systems for this study. Mallards represent wild bird populations and they are an EPA recommended species because they do well in a laboratory environment. Mallard habitats include ponds, lakes and marshes, and Centre Analytical Laboratories, Inc. Centre A nalytical Laboratories, Inc. Page 4 o f 43 Page 60 o f 104 Centre Study N o.: 023-042 Centre Protocol No. OOP-023-042 they are considered aquatic grazers. The use of these matrices for the study was to determine if PFOS was deposited in the liver and senim of mating adults that were fed PFOS. 7. SAMPLE PROCESSING, STORAGE AND IDENTIFICATION No processing will be required for the serum samples. Due to the small amount of sample available, the liver samples will not be homogenized prior to extraction; however, they will be homogenized by lying the samples on a flat surface and mashing them by hand as best as possible. Each sample will be assigned a unique sample identification number at Centre, which will be used for tracking and identification of the samples. The samples will be stored in a temperature-monitored freezer, maintained at < -10 C, except when removed for extraction and analysis as described in the method. The samples will be kept isolated from the test substance during storage. Sample receipt and storage location and conditions during the study will be documented. All samples and any resulting sample extracts will be identified with a unique label or sample number. Such identification will be either on the contain-or cross-referenced to the container. 8. ANALYTICAL METHOD ' The serum samples will be analyzed according to the analytical method titled "Extraction Of Potassium Perfluorooctanesuifonate Or Other Fluorochemical Compounds From Serum For Analysis Using HPLC-Electrospray/Mass Spectrometry" (3M method number ETS-8-4.1) and the control liver samples will be analyzed according to the method titled "Extraction Of Potassium Perfluorooctanesuifonate Or Other Fluorochemical Compounds From Liver For Analysis Using HPLC-Electrospray/Mass Spectrometry" (3M method number ETS-8-6.0). The following modifications w ill be applied to each method: 1. There will be no surrogate standard used in the extraction procedure. The stock, fortification, and calibration standards will be prepared as follows: Stock Solution Prepare a stock solution of PFOS at 100 pg/mL by weighing out 10.0 mg of analytical standard (corrected for percent salt and percent purity). Adjust final volume to 100 mL with methanol in a 100-mL volumetric flask. Store this stock solution (in 125-mL LDPE bottles) in a refrigerator at 2C to 6C for a maximum period of 6 months from the date of preparation. Fortification Solutions a. 1.0 ug/mL Fortification Solution - Pipette 1.0 mL of the 100 pg/mL stock solution into a 100 mL volumetric flask. Bring up to volume with methanol.

The liver samples will not be processed to make the homogenate described in the method Section 12.2 to 12.12. Due to limited sample available, samples will be mashed on a flat surface by hand prior to extraction. 3. The sample weight for liverwill be 0.50 g ( 0.05) and the sample volume for serum will be 100 pL. The amount of 0.5 M TBA added to the serum sample will be 0.5 mL and the amount of 0.25 M sodium carbonate/sodium bicarbonate buffer added will be 1.0 mL. Samples will be placed on a wristaction shaker for - 20 min. at level 10 and then centrifuged for - 15 min @ -3000 rpm. The samples will only be filtered with 0.2 pm nylon mesh filter if necessary. Samples will be reconstituted in a final volume of 1 mL of methanol for both matrices. Centre Analytical Laboratories, Inc. Centre A nalytical Laboratories, Inc.

Actual values may vary from instrument to instrument Also, these values may be changed from time to time in order to optimize for greatest sensitivity. The mass spectrometer is tuned using a 0.5|ig/mL PFOS solution, prepared via dilution of the stock solution in methanol. The solution is infused (using a "T" connector) at 10 pL/min into a 0.2 mL/min stream of mobile phase consisting of 40% methanol and 60% 2 mM ammonium acetate. The analytes are initially tuned for the parent ion and then tuned for the product ion. Once the instrument is tuned, the optimized parameters are saved as a "tune file". This tune file is then used during routine analysis. The tuning procedure may be repeated as necessary to ensure optimal sensitivity.

Inject the same volume (between 10 to 20 pL) of each calibration standard (prepared in MeOH) into the LC/MS/MS. b. Use linear, 1/x weighted standard curves for quantification. Linear standard curves are generated for each set by linear regression using the appropriate software system. Any calibration standards falling outside 30%, based on its calculated concentration, must Centre Analytical Laboratories, Inc. Centre A nalytical Laboratories, Inc. Page 8 o f 43 Page 64 o f 104, Centre Study N o.: 023-042 Cintre Protocol No. OOP-023-042 be excluded from the calibration curve. However, the total number of calibration standards that may be excluded must not exceed 30% of the total number of standards injected. c. The correlation coefficient (r) for calibration curves generated must be >0.9925 (r2>0.985). If calibration results fall outside these limits, then appropriate steps should be taken to adjust instrument operation, and the relevant set of samples must be reanalyzed. Sample Analysis Inject the same volume used for the calibration standards (between 10 to 20 pL)- of each sample, fortification, control, etc. into the LC/MS/MS. Each sample must be analyzed in duplicate. a. Standards corresponding to at least six concentrations must be included in an analytical set b. Inject an entire set of standards (six) at the beginning of the run and inject standards interspersed about every 5-10 samples. All sample injections must be bracketed by standard injections. c. Each set of samples analyzed (not to exceed 25) must include at least . one reagent control (extraction solvents only), at least one matrix control, and two matrix control samples fortified at known . concentrations and carried through the procedure to verify recovery. d. The concentration of each sample, fortification, control, etc. is determined from the standard curve based on the peak area of the analyte in all standards injected during a set The standard responses must bracket responses of the residue found in the sample set. If necessary, dilute the samples and re-analyze to give a response within the standard curve range. e. Fortification recoveries within 80 to 120% are acceptable for fortifications at the LOQ level. Recoveries between 80 to 120% are acceptable for fortifications at levels greater than the LOQ. Failure to . meet these criteria requires an investigation of cause and a full reanalysis of the affected samples. f. Samples in which no peaks are detected at the corresponding analyte retention times will be reported as ND (not detected). Samples in which peaks are detected at the corresponding analyte retention times but are less than 3:1 signaknoise will be reported as NQ (not quantifiable). Centre Analytical Laboratories, Inc. Centre A nalytical Laboratories, Inc. Page 9 of 43 Page 65 o f 104 Centre Study N o.: 023-042 Centre Protocol No. OOP-023-042 g. Background levels of analyte found in control/blank samples that correspond to values below the LOQ, but are still quantifiable, will be used to correct fortification recoveries. h. If samples are not loaded on the instrument to be analyzed the day they are extracted, samples must be stored refrigerated at approximately 2C to 6C until analysis and analyzed preferably within a week. 9. EXPERIMENTAL DESIGN Samples obtained by Wildlife International Ltd. have been shipped to Centre Analytical Laboratories, Inc. for analysis. All samples will be analyzed according to methods, "Extraction, of Potassium Perfluorooctanesulfonate or Other Fluorochemical Compounds From Serum for Analysis Using HPLC-Electrospray/Mass Spectrometry" and `Extraction of Potassium Perfluorooctanesulfonate or Other Fluorochemical Compounds From Liver for Analysis Using HPLC-Electrospray/Mass Spectrometry" with the modifications detailed in Section 8. Methods to control bias will include assay of untreated control samples, fortification of untreated control samples to obtain recovery data, and replicate analysis of fortified samples to provide an indication of reproducibility. The average recovery and relative standard deviation of the fortified samples will be calculated. Also, the average residue found and standard deviation for each matrix will be calculated. 10.
