Tba taat waa conducted for 3M Company for 48 houra from September 5 to 7, 1995, at T.R. Hilbury Laboratories, Inc. in Marblehead, Maaaachuaetta. It waa conducted by Peter Kovalki, Jeanne Magazu, Jacqueline Neviua, Keven Steven, Peter Heviua, Robert Boeri, and Timothy Hard according to the protocol developed for T.R. Hilbury study Humber 889-T8. K2803-2 waa supplied by the sponsor. The teat waa performed under static conditions with five concentrations of test substance and a dilution water control at a temperature of 19.3-20.4*C. The dilution water was filtered deionized water collected at Marblehead, Massachusetts and adjusted to a hardness of 176 mg/L as caco,. Aeration was not required to maintain dissolved oxygen concentrations above an acceptable level. Nominal concentrations of N2803-2 were 0 (control), 13, 22, 36, 60, and 100 mg/L. Daphnid used in the test were less than 24 hours old at the start of the test. They were produced at T.R. Hilbury Laboratories and acclimated under test conditions for their entire life (cultures that produced test specimens were maintained at test conditions for more than 7 days). After 48 hours of exposure the control daphnids had an average wet weight (blotted) of 0.26 mg. All daphnids were in good condition at the beginning of the etudy. Exposure of daphnids to the test substance resulted in a 24 hour median lethal concentration (LC50) >100 mg/L N2803-2, a 48 hour LC50 of 93 mg/L H2803-2 (95 confidence interval 74 to >100 mg/L), a 24 hour median effective concentration (EC50; based on immobilization) of 72 mg/L (95% confidence interval 63 to 83 mg/L), and a 48 hour EC50 of 62 mg/L H2803-2 (95* confidence interval 36 to 100 mg/L). The 48 hour no observed effect concentration (NOEC) .is 13 mg/L. f BACK TO MAIN BACK TO MAIN VII. INTRODUCTION This atudy was sponsored by 3H Company St Paul, Minnesota. Tha objactlva of tha atudy was to datarmlna tha 24 and 48 hour median lathal concantrationa (LCSOa) and median affactlva concantrationa (EC50a) of tha taat aubatanca to tha daphnid, Daphala magna, a freshwater invartabrata, undar atatlo condltlona Tha taat protocol waa baaad on U.s. EPA methods (U.S. EPA, 1993). Tha raport containa aactlona that describe tha mathoda and materials employed in tha atudy, and raaulta of tha investigation.

Hilbury Laboratoriea Sample Number 520) waa delivered to T.R. Hilbury Laboratoriea on Auguat 14, 1995 in a cardboard box at ambient temperature. It waa contained in an approximately 50 ml glaaa jar. The label attached to the bottle included the following information) "N2803-2". N2803-2 (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 will be returned to the sponsor. DILUTION HATER) Hater used for acclimation of test organisms and for all toxicity testing was deionized water collected at T.R. Hilbury Laboratories in Marblehead, Massachusetts. Hater was adjusted to a hardness of 160 180 mg/L as CaCO, and stored in 500-gallon polyethylene tanks where it was aerated and continuously passed through a particle filter, ultraviolet sterilizer, and activated carbon. Results of chemical analysis of a representative sample of water are presented in Table 1. TEST ORGANISM) Juvenile daphnids, Daphala magna, employed as test organisms were less than 24 hours old at the start of the test. They were from a single aource and were identified using an appropriate taxonomic key. Test specimens were produced by adult daphnids that were maintained under test conditions at the T.R. Hilbury facility for more than 7 days. f j j j j } i i 1 j T.R.

Tha cultura vaa auppliad with a yaaat/trout chow mix (Lott DC02) and tha fraahwatar alga, Salenaatrun caprlcornutua, daily during acclimation. Daphnida wara not fad during tha teat. Control daphnida, blottad and weighed at tha concluaion of the toxicity taat, averaged 0.26 mg and tha loading rate during the definitive toxicity test waa approximately 10.4 mg/L. TOXICITY TESTING s A static screening teat was conducted from August 23 to 25, 1995 with five concentrations of test substance and a dilution water control. Nominal concentrations of N2803-2 were 0.10, 1.0, 10, 100, and 1,000 mg/L. After 48 hours of exposure there was 100% survival in the control and at 0.10, 1.0, 10, and 0% survival at 100 and 1,000 mg/L. The definitive toxicity test waa performed from September 5 to 7, 1995, according to T.R. Wilbury Protocol 889-TH (Acute Toxicity of N2803-2 To The Daphnid, Daphnla magna). Tho protocol, which waa signed by the study director on August 16, 1995, is based on procedures of the U.s. Environmental protection Agency (1993). A summitry of the test system is presented in Table 2. The test was conducted at a target temperature of 20 1*C with five concentrations of test substance and a dilution water control. Nominal concentrations of the test substance were: 0 mg/L (control), 13, 22, 36, 60, and 100 mg/L. A 200 mg/L stock solution was formulated by combining 0.200 g test substance and dilution water in a Class A volumetric flask and adjusting the final stock solution volume to 1,000 ml. Appropriate amounts of this stock solution were added to dilution water in teat vessels to forsnilate test media without the use of a solvent. Twenty daphnida were indiscriminately and equally distributed among two replicates of each treatment. The test was performed in 300 ml glass beakers that contained 250 ml of test solution (water depth was approximately 9 cm). Test vessels rare randomly arranged during the 48 hour test (a random numbers table was used to select the location of each vessel) and they were loosely covered.

RESULTS Insoluble material was not noted during the teat. Biological and water quality data generated by the acute toxicity test are presented in Table 3 and Appendix A, respectively. The measured concentrations of dissolved oxygen ranged from 8 . 6 to 9.0 ng/L, the temperature ranged from 19.3 to 20.4*C, conductivity ranged from 670 to 720 pmhos/cm, and pa ranged from 8.3 to 8 .6 . one hundred percent survival occurred in the control exposure and these daphnids did not exhibit any sublethal effects. The 24 and 48 hour LC50s and EC50s for daphnids exposed to N2803-2 are presented in Table 4. The 48 hour LC50 for daphnids exposed to N28032 is 93 mg/x> (95% confidence interval 74 to >100 mg/L) and the 48 hour EC50 is 62 mg/X. (95% confidence interval 36 to 100 mg/L). The slope of the 48 hour dose response curve (based on mortality and immobilization) is 6.1. The 48 hour no observed effect concentration (NOEC) is 13 mg/L. T.X.
