GENERAL INFORMATION MR: H: TEST CODE: MATERIAL TESTED: PURITY: COMPOSITION: Poly(difiuoromethylene), alpha-fluoro-omega-[2((2-methy-1-oxo-2-propenyl)oxy}ethyll-, polymer with 2-ethyihexyl 2-propenoate, 1,1-dichloroetFiene, 2-hydroxyethyl 2-methyl-2-propenoate. N- (hydroxymethyl)-2-propenamide, and alpha-(2methyl-1 -oxo-2-propenyl)poly(oxy-1,2-etrianediyi) Sponsor: Notebook SO: SUMMARY H-19913 toxidty was low (96-hour LC50 between 500 to 5000 mg/L) in a 9ff-hour unaerated, static, acute test using fathead minnows, Pimephales promelas. Nominal concentrations of H-19913 tested were 0.0.50,1.0, 50, 500, and 5000 mg/L- Mortalities of 0. 0.0,0,0. and 100%, respectively, were observed. Based on visual observations, the test substance was soluble in well water at 0.5 and 1.0 mg/L. The three highest test concentrations appeared cloudy. Dissolved oxygen and pH were measured in 0,0.5, 50 and 5000 mg/L nominal concentrations. The dissolved oxygen at 0 and 96 hours or at total mortality were 8.5,8.5,8.6 and 8.5 mg/L and 9.0, 8.7,8.4 and 0.7 mg/L, respectively. The lowest dissolved oxygen value resulted froin the decomposition of dead fish at 5000 mg/L. The pH values at 0 and 96 hours or at total mortality were 7.0. 7.1, 7.2 and 7.2 mg/L and 7.5. 7.7, 7.7 and 7.0 mg/L, resp^ctwely- Page I of 2 DU PONT HLR 879-92 WORKBY: j.-------^ - LYNNS.FORD,/ TOXICOLOGY ASSOCIATE ^ ^^ MO^AY/YEAR ^ ^ APPROVED BY- 6^-Aft^ C fCftou^r- GUAT-UANC.KREAMER RESEARCH TOXICOLOGIST ^//6/^2.

H^mMS WO HKTROPS A. Animal Husbandry Young adult fMl He^ Zealand White rabbits were received from Hr Narland, Havitt, Nev Jers<ty or Baxleton Research Product*, Denver, Pennsylvania. The rabbit* vere housed singly In suspended, stainless steel, vire-meah cages* pReh rabbit y-- i|nd unique identification number which vac recorded on card affixed to the c(. The rabbif were offered approxiiwtely 125 (ra-- of Purina Certified Niyh Fiber Rabbit Chov* 532S daily durini; th study and vafr vaa available ad libitur except ae noted under Protocol. Rabbita vare quarantined, velghed, and obaerved for Igeneral health for approxiBately 2 veekc. Aniiial rool-- were --infixed on a tiler-controlled, 12-hour light/12-hour dark cycle. Envtronient<4 conditions of the room were targeted for a tenperature of 20*C i 2*C and relative hunidlty of 50X * 10X. Any excurciona outalde theae faneec were of all MKnitude and/or brief duration and did not adversely affect the validity of the tudy. B. Protocol On the day prior to tteatent, the hair of 6 female Nev Zealand White rabbits vaa closely shaved to expose the akin froi the scapular to the lumbar region of the backf The body weights of the rabbits ranged from 2947 to 3320 gram on the: day of treatmnt, Bach rabbit vas placet into stock which had been fitted vich a piece of rubber sheeting, approximately S" x 16". The rabbits reaained in the stocks throughout he exposure period and during that time did not have access to food or wa ;er. In the absence of visible evidence to the contrary, the test aubstaiiee va assumed to b stable under the conditions of admlnlstrat:.on. Approximately 0,5 aL of H-19913 was applied directly to a 2-inch gauze square that was then placed on the test site. The patch vas,held in place vith non-irritating tape. The rubber sheeting vas then wrapped around the animal and secured vith clips to retard evaporation and to keep the test substance in contact vith the skin without undue pressure 7 - . Sanitized.
