3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10heptadecafluoro- (batch number P00/001) to three terrestrial plant species was determined in a seedling emergence test over a period of 21 days, from November 21, 2002 to February 07, 2003 (for detailed test periods see test conditions) according to OECD 208 Draft document, July 2000 at the DR.U.NOACK-LABORATORIUM FR ANGEWANDTE BIOLOGIE, Sarstedt, Germany. The test was conducted with the nominal concentrations 10.0 - 32.0 - 100 - 320 - 1000 soil dry weight (DW) (oats and soybean) 6.25 - 12.5 - 25.0 - 50.0 - 100 mg/kg soil dry weight (DW) (rape) selected on the basis of a preliminary phytotoxicity test. To reach a sorption equilibrium the application of the test medium was performed 24 h before the seeds were sown. Test systems were one monocotyledon (oats (Gramineae)) and two dicotyledons (rape (Brassicaceae) and soybean (Leguminosae)). The test containers were bottom watered with nutrient solution as needed. A solvent control without test item (quartz sand only spiked with tert.-buthyl-methyl-ether) was tested under the same conditions as the test groups. To exclude effects of the solvent tert.-buthyl-methyl-ether a second control without solvent was tested. The solvent tert.buthyl-methyl-ether caused no inhibitory effects in shoot height, biomass growth, and rate of emergence. No statistically significant differences were found between the control and the solvent control. For rape, enhanced growth was observed for the solvent control relative to the control. This promotion was not significant for this study. Therefore for calculations the replicates of the control and solvent control were summarized in a pooled control group. The toxic effects of the test item were determined on day 7, 14 and 21 by visual observations (number of emerged seedlings, phytotoxic effects and number of dead plants) and on day 21 by shoot height and shoot fresh weight determination. Shoot height, fresh weight and number of emerged seedlings were checked for statistically significant differences relative to the controls and the NOEC, the EC25- and EC50-values were calculated (Table 1-3). DR.U.NOACK-LABORATORIUM FR ANGEWANDTE BIOLOGIE Report 1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoroTerrestrial Plants Toxicity, Seedling Emergence acc. to OECD Guideline 208 (Draft July 2000) Page 9 of 51 Project-No. 020719CK Study-No. TNC84113 Table 1: Shoot Height: NOEC, EC25 and EC50 Values with Confidence Range (p) Species NOEC* [mg/kg DW] EC25 [mg/kg DW] p = 95% EC50 [mg/kg DW] [mg/kg DW] oats rape 1000 50.0 > 1000 80.2 - 65.6 - 97.9 > 1000 > 100 soybean 1000 > 1000 - > 1000 p = 95% [mg/kg DW] - - - Table 2: Fresh Weight: NOEC, EC25 and EC50 Values with Confidence Range (p) Species NOEC* [mg/kg DW] EC25 [mg/kg DW] p = 95% EC50 [mg/kg DW] [mg/kg DW] p = 95% [mg/kg DW] oats 1000 > 1000 - > 1000 - rape 25.0 51.7 44.0 - 60.8 73.7 62.6 - 86.7 soybean 320 > 1000 - > 1000 - Table 3: Number of Emerged Seedlings: NOEC, EC25 and EC50 Values with Confidence Range (p) Species NOEC* [mg/kg DW] EC25 [mg/kg DW] p = 95% EC50 [mg/kg DW] [mg/kg DW] p = 95% [mg/kg DW] oats 1000 > 1000 - > 1000 - rape 100 > 100 - > 100 - soybean 1000 > 1000 - > 1000 - - not determinable * The highest tested concentration of the test item at which no statistically significant effect is observed relative to control DR.U.NOACK-LABORATORIUM FR ANGEWANDTE BIOLOGIE Report 1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoroTerrestrial Plants Toxicity, Seedling Emergence acc. to OECD Guideline 208 (Draft July 2000) Page 10 of 51 Project-No. 020719CK Study-No. TNC84113 2 Characterisation Data of the Test Item TEST ITEM 1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10heptadecafluoro- Batch Number P00/001 CAS RN 678-39-7 Chemical characterization 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecane-1ol (EINECS) Purity C8-perfluoroalkylethanol: 99.8 % (a/a), sum perfluoroalkylethanol 99.9 % (a/a) Appearance Yellowish solid wax Water solubility 134 g/L at 12 degree C, Std 29 g/L, n=8 (DuPont, 2002) 137 g/L at 25 degree C, Std 53 g/L, n=17 (DuPont, 2002) Stability in water Density Stable at test conditions Ca. 1.7 g/cm3 Expiry date Recommended storage Storage at testing facility Retention Identification parameter at testing facility Unlimited if stored under the recommended conditions.

The concentrations of the test item are expressed in terms of the dry weight of the soil. DR.U.NOACK-LABORATORIUM FR ANGEWANDTE BIOLOGIE Report 1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoroTerrestrial Plants Toxicity, Seedling Emergence acc. to OECD Guideline 208 (Draft July 2000) Page 16 of 51 Project-No. 020719CK Study-No. TNC84113 ENVIRONMENTAL CONDITIONS Source of light Watering / Fertilisation Nutrient solution The test item was weighed out and dissolved in tert.-buthylmethyl-ether to produce a number of stock solutions. A specified amount of the appropriate test item stock solution was mixed with quartz sand. After the solvent had volatilised out of the quartz sand, the treated quartz sand was mixed with the soil. The soil was mixed carefully with a hand-mixer (KRUPS) to insure a homogeneous distribution of the test item in the soil. The amount of quartz sand added was the same for each test concentration (1 %). After 24 h the treated soil was placed in the test container and the seeds were sown (see above). nominal Oats Soybean Rape Temperature [C] 20 10 16 - 24 16 - 24 17 - 26 Relative humidity [%] > 60 68 - 100 70 - 100 74 - 100 Photoperiod [h] 16 16 16 16 Illumination [lx] > 3500 3600 1100 5300 1400 3400 1100 Special-fluorescent tube FLUORA (Art-No. 25414925) Special-fluorescent tube DAYLIGHT (Art.-No. 25414922) Origin: HOKLATHERM GMBH, Postfach 206, D-26687 Apen Bottom watering of the test containers with nutrient solution as necessary.

During the observation period the replicates were observed every 7 days for number of emerged seedlings, number of dead plants and visual phytotoxic effects. Observations included all variations, either inhibitory or stimulatory, between the treated replicates and the pooled controls. Such variations were phytotoxic symptoms (e.g. chlorosis, necrosis, wilting), formative effects and growth and development rates. At the end of the study the number of emerged seedlings, number of dead plants and phytotoxic effects were determined and shoot height and shoot fresh weight were measured. TEST DESCRIPTION Day -1: Start (day 0): Every working day: Day 7, 14, 21: Test end: A preliminary NON-GLP test was performed with 3 soil concentrations (10 - 100 - 1000 mg/kg DW), and additionally for rape a single concentration of 1 mg/kg DW was tested. Based on the results of the preliminary test, the main study was performed with five concentrations from 10 to 1000 mg/kg DW with a factor of 10 (oats and soybean) and from 6.25 to 100 mg/kg DW with a factor of 2 (rape). The test medium was heated to 50 C, weighed out, dissolved in tert.-buthyl-methyl-ether and mixed with quartz sand. After the solvent had volatilised out of the quartz sand (ca. 1 h), the treated quartz sand was mixed with the soil. The treated soil was placed in the test containers and the seeds were sown. Test containers were bottom watered and fertilised as needed. The plants were observed for number of emerged seedlings, visual phytotoxic effects and number of dead plants. Final shoot heights and fresh weight measurements were done. DR.U.NOACK-LABORATORIUM FR ANGEWANDTE BIOLOGIE Report 1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoroTerrestrial Plants Toxicity, Seedling Emergence acc. to OECD Guideline 208 (Draft July 2000) Page 18 of 51 Project-No. 020719CK Study-No. TNC84113 STATISTICS AND CALCULATIONS NOEC of biomass/ be emerged seedlings One Way Analysis of Variance (ANOVA) and DUNNETT'S Test were carried out for the determination of statistically significant differences compared to pooled control replicates. When running a One Way Analysis of Variance a Normality Test and an Equal Variance Test were done first. P-values for both Normality and Equal Variance Test are 0.05. The a-value for ANOVA and DUNNETT'S Test (acceptable probability of incorrectly concluding that there is a difference) is a=0.05. No statistically significant differences were found between the control and the solvent control. Therefore for calculations the replicates of the control and solvent control were summarized in a pooled control group. All dead plants were measured and weighed and included in calculations if possible according to the guideline. EC-values and confidence Intervaly of growth Calculations were carried out via probit analysis. Probit values were taken from WEBER (1986). Confidence intervals were calculated according to a standard procedure (BREITIG & TMPLING 1982).

For rape decrease in length was observed at the concentration 100 mg/kg DW as medium to strong effect. For details see Table 25 - 27. The EC50-value for shoot height was not calculable in the tested concentration range for the tested plant species because no test item related inhibition occurred. The EC50- values for shoot height were > 100 mg/kg DW for rape and > 1000 mg/kg DW for oats and soybean, respectively (Table 1). Significant differences in comparison to the control were determined at the concentration 100 mg/kg for rape. The EC50- values for fresh weight was determined for the plant species rape at 73.7 mg/kg DW (Table 2). The EC50- values for fresh weight were > 1000 mg/kg DW for oats and soybean (Table 2). Significant differences in comparison to the control were determined at the concentration 50 and 100 mg/kg for rape and at the concentration 1000 mg/kg for soybean. The EC50- value for seedling emergence was not calculable in the tested concentration range for the tested plant species. The EC50- values for seedling emergence were > 100 mg/kg DW for rape and > 1000 mg/kg DW for oats and soybean, respectively (Table 3). 7 Validity Criteria The control treatment validity criteria according to the test guideline were fullfilled: - a minimum of 65 % emergence - the mean seedling growth exhibited no visible phytotoxic effects - the mean survival of the plants was at least 90 % at the end of the test DR.U.NOACK-LABORATORIUM FR ANGEWANDTE BIOLOGIE Report 1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoroTerrestrial Plants Toxicity, Seedling Emergence acc. to OECD Guideline 208 (Draft July 2000) Page 30 of 51 Project-No. 020719CK Study-No. TNC84113 8 Literature (1) BREITIG & TMPLING (1982): Methoden der Wasseruntersuchungen Bd.II, VEB GUSTAV FISCHER VERLAG, Jena.
