P00/001) on the development of the free living soil nematode Caenorhabditis elegans were determined in a water-sediment system. The study was carried out according to Tr a u n s p u r g e r et al. (1997). Test duration was 72 hours. The study was conducted from 2002-11-22 to 2002-11-25 at Dr .U.No a c k La b o r a t o r iu m Fr A n g e w a n d t e Bio l o g ie , Sarstedt, Germany. A limit test was conducted with a limit concentration of 1000 mg/kg selected on the basis of a preliminary test. Fifty nematodes were exposed to the limit test concentration. Thirty nematodes were tested in an untreated sediment control. A solvent control (tert.-methyl-butyl-ether, MTBE) and a liquid control were also tested with 2 replicates (10 nematodes per replicate) for each control treatment. The effects of the test item 1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoro- are summarised in Table 1.

Determination of the potential impact of 1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoro- on the free living soil nematode Caenorhabditis elegans. TEST SYSTEM Reason for the selection Source Food medium Feeding Food Caenorhabditis elegans (nematoda) N2, var. Bristol, wild type lab strain According to the literature (Tr a u n s p u r g e r et al., 1997) Caenorhabditis elegans is suitable for this kind of study. Breeding was performed in the test facility at 20 2 C in the dark. Origin: Ca e n o r h a b d it is Ge n e t ic s Ce n t e r , University of Minnesota, 250 BioScience Center, 1445 Gortner Avenue, St. Paul, MN 55108 1095, USA All nematodes used in the test originated from the same delivery of the supplier and the same stock. They were not used in another test. Medium M9, according to Gr a t z e r & A hlf (2001) Feeding occurred parallel to test start in the test vessels. Liquid culture of Escherichia coli OP 50, cultured in the test facility in LB-Medium and resuspended in M9 - Medium.

The solvent was volatilized out of the quartz sand and the sand mixed with artificial sediment to produce the desired limit test concentration. A limit concentration of 1000 mg /kg artificial sediment was used for the study. 70 g quartz sand terf-methyl-butyl-ether 2.4996 g of the test item were weighed out and dissolved in 100 mL terf-methyl-butyl-ether. 4 mL of the test item stock solution has been mixed with 70 g quartz sand, necessary for an entire amount of 100 g artificial sediment. After volatilization of the solvent out of the quartz sand, the treated quartz sand was carefully mixed with the artificial sediment to insure a homogeneous distribution of the test item. The amount of quartz sand added was the same for the limit test concentration and the untreated artificial sediment control. After 24 h of equilibration under test conditions 0.5 g of the treated sediment was added to the test vessels. Three replicates with 10 nematodes per replicate using M9-Medium and artificial sediment (without test item) were tested under the same test conditions as the test item replicates. Two replicates with artificial sediment and quartz sand treated with tert.methyl-butyl-ether without test item were used as solvent control medium. The liquid control solely served as the validity control. M9-Medium (0.5 mL) without sediment was tested using 2 replicates with 10 nematodes per replicate under the same test conditions as the test item replicates. No reference item is recommended according to the literature. TEST METHOD Test duration A static test was performed. 72 h after transfer of the test organisms into the test vessels. 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-heptadecafluoroEffects on the Development of Caenorhabditis elegans in a W ater-Sedim ent System acc. to T r a u n s p u r g e r et al.

Test sediment amount 0.5 g (dry weight, with and without test item) per test well, mixed with 0.5 mL of the food. Food M9-Medium (see above) inoculated with Escherichia coli OP50 (densitiy of approx. 10 cells/mL) Number of test nematodes per replicate 10 Replicates 5 replicates per limit test concentration, 3 replicates per untreated sediment control, 2 replicates per liquid and solvent control. Age of nematodes First stage juveniles (body length ca. 270 jm ) obtained by filtering a fresh culture of nematodes through 10 jm and 5 jm mesh size nylon nets. Preparation of test vessels Prior to test start, 0.5 g sediment mixed with the test item was added into each test vessel. The untreated sediment control vessels were filled with 0.5 g sediment without test item. Introduction of the larvae Prior to test start 0.5 mL of the food medium was added to the vessels with the test item treated and the control sediment. 0.5 mL of the food medium was added to the liquid control. Ten selected first stage juveniles were randomly transferred to each test vessel by a sterilized micropipette. After addition of the nematodes, the test vessels were kept on shaking desks and incubated for 72 h. Temperature 20 1 C Light intensity Continuous dark Feeding Food was provided at test start in M9-Medium. 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-heptadecafluoroEffects on the Development of Caenorhabditis elegans in a W ater-Sedim ent System acc. to T r a u n s p u r g e r et al.

The number of living nematodes in the liquid control was observed under a microscope at test end to ensure the vitality of the test organisms throughout the exposure. The test vessels were heated (50 C, 5 min) to kill the worms and afterwards the nematodes were stained using an aqueous solution of Ro s e -Be n g a l and stored at -20 C until further extraction and measurements. Extraction of the test organisms from sediment The sediment was mixed with approx. 6 mL of diluted Lu d o x and centrifuged using a swing-out centrifuge (10 min, 700-800 g). The resulting supernatant with the nematodes was decanted in a petri-dish. Criteria of effects The extracted nematodes were observed using a microscope. Body length was measured with a microscale to an accuracy of at least 0.001 mm. Number of eggs inside the nematodes was counted and recorded.

Based on the results of this preliminary test, the definitive study was performed at the limit concentration of 1000 mg/kg. A sediment control, a solvent control and a liquid control (each without test item) were tested under the same conditions as the test item treatment. At test end (after 72 h) the worms were examined for survival (liquid control), body length and egg production. Measurements and observations were carried out as described above. 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-heptadecafluoroEffects on the Development of Caenorhabditis elegans in a W ater-Sedim ent System acc. to T r a u n s p u r g e r et al.

The following evaluations were made: - Growth: Body length in pm - Egg production: Number of eggs inside the body - Fertility: [%] gravid worms (worms with > 1 egg) The number off eggs per worm was calculated for each replicate according to formula 1: R = ne/nn R = Reproduction ne = Number of eggs at test end nn = Number of nematodes at test end (1) Fertility [%] of worms was calculated according to formula 2: F = nex 100 / nt F = Fertility in % ne = Sum of worms with > 1 egg nt = Sum of worms introduced per treatm ent (2) STATISTICAL ANALYSIS SOFTWARE ANOVA has been used for comparison of mean values of the replicates. Tests for a normality and homogeneity of variances were conducted prior to ANOVA. P-values for both normality and homogeneity of variances were 0.05. Kr u s k a l -W a l l is ANOVA on Ranks was used in case a non-normal data distribution. The a -value for ANOVA and Kr u s k a l -W a l l is ANOVA on Ranks was a =0.05.
