The test was conducted for 3x c a p a n y for 48 hours frcm September 5 to 7, 1995# at T.R. Wilhury Laboratories, Ina. in marblehead, Uh88clChUSOttm. It was conducted by Peter xowalski, ~0.~0 Hagasu, Jacqueline Nevius, Keven Stevens, Peter NwfU8, Rob.rt h r i , and Timothy ward according to the protocol developed for T.R. Wilbury study Wmb.r 889-T8. U2803-2 was sapplied by the sponsor. Tho test WAS performed under static conditions with five concentrations of test substance and h dilution water control at a temperature of 19.3-20.4.C. The dilution water Was filtered deionized water collected at Uhrblehead, Xasrachusetts and adjusted to a hardness of 176 mg/L as CACO,. Aeration was not required to maintain dimsolved oxygen concentrations above an acceptable level. Nominal concentrations of N2603-2 were 0 (control), 13, 22, 36, 60, and 100 mg/L. DhphnidS used in the test were lesa than 24 hours 011 at the start of the test. They were produced at T.R. Wilbury Laboratories and acclimated under test conditions for their entire life (cultures that produced test specimens were mhintained 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 daphnidr were in good condition at the beginning of the study. - Exposure of daphnids to the test substance resulted in a 24 hour median lethal concentration (Lc50) >lo0 mg/L N2803-2, a 48 hour LCSO of 93 mg/L N2803-2 (951 confidence interval 74 to >IO0 mg/L), a 24 hour median effective concentration ( ~ C 5 0 ; based on immobilization) of 72 mg/L (958 confidence interval = 63 to 83 mp/L), and a 4H hour EC50 of 62 mg/L N2803-2 (958 confidence interval = 36 to 100 mg-/Ll.. observed effect concentration (NOEC) is 13 mg/L.

It was containod i n an approximately 50 ml glass jar. The label attached to the bottle included i j the following information: "2803-2". N2803-2 (a clear liquid) was supplied by 3H Company, St Paul, Minnesota. Prior to use the test substance was stored in the dark at rocm I temperature. The test substance was assuaed 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. DILDTIOU WATER: Water used for acclimation of test organism and for all toxicity testing was deionized water collected at T.R. wilbury Laboratoriea i n Harblehead, msaachusetts. Water was adjusted to a hardness of 160180 mg/L as CaCO, and atored in 500-gallon polyethylene tanka where it was aerated and continuou8ly 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.

TOXICITY TESTIIIQ: A static mcreening teat wa8 conducted from August 23 to 25, 1995 with five concentrations of teat subatmcm and a dilution water control. Nominal concentrations of N2803-2 were 0.10, 1.0, 10, 100, and 1,000 mg/L. After 48 hour8 of exposure there Was 100% survival in the control and at 0.10, 1.0, 10, and 0% SUNiVal at 100 and 1,000 mg/L. The definitive toxicity test Yam performed fram September 5 to 7, 1995, according to T.R. Wilbury Protocol 8fl9-TE (Acute Toxicity of N2803-2 T o The Daphnid, Daphnia magna). Tho protocol, which was signed by the mtudy director on August 16, 1995, is bused on procedures of the U.S. Environmental Protection Agency (1993). A 8ummary of the test system is presented in Table 2. The test was conducted at a target temperature of 20 i 1.C with five concentrations of test substance and a dilutfcn water contrcl. N d n a l concentrations of the teat 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 mubstance and dilution water in a Class A volumetric flask and adjusting the final rtock solution volume to 1,000 m l . Appropriate amounts of thim stock solution vera added to dilution water in test vensols to formulato test media without the use of a solvent. I Twenty daphnidm w r e indircrhdnately and equally distributed among two replicatom of each treatment. Tho test was perfom3d in 300 m l glans beakorr that containod 250 ml of test solution (water depth was approximately 9 cm). Tert v08sel8 were randomly arranged during the 48 hour tost (a random number. table waa used to aeloct the location of each vessel) and they were loosely covered.
