ACUTE TOXICITY TO AQUATIC INVERTABRATES (DAPHNIA MAGNA)
TEST SUBSTANCE________________________________________________
Identity: Perfluorooctanoic acid, ammonium salt; may also be referred to as PFOA ammonium salt, Ammonium perfluorooctanoate, PFO, FC116, FC-126, FC-169, FC-143 or as the major component of FC1015. (Octanoic acid, pentadecafluoro-, ammonium salt, CAS # 3825-26-1)
Remarks: The test sample is FC-1015. It's purity was not sufficiently characterized, though current information indicates is a 30% straight carbon chain version of FC-143 in 80% water. The 3M product lot number was "HOGE 205".
The following summary applies to the test sample as a mixture of the test substance in water solution with incompletely characterized concentrations o f impurities. Data may not accurately relate toxicity of the test sample with that o f the test substance. Data was used to compare toxicity of the branched/straight chain ammonium perfluorooctanoate homologue mixture in FC-143 vs. what is supposed to be the 100% straight carbon chain ammonium perfluorooctanoate in FC-1015.
METHOD:________________________________________________________
Method: USEPA - TSCA, Guideline 797.1300
Type: Static acute
GLP: No
Year completed: 1996
Species: Daphnia magna
Supplier: In-house cultures. Initial brood stock from Aquatic BioSystems,
Fort Collins, Colorado
Analytical monitoring: Temperature, pH, conductivity and DO
Exposure period: 48-hours
Test organism age: <24 hours old
Statistical method: Probit analysis
Test conditions:
Dilution water: Deionized water adjusted to a hardness of 160-180
mg/L (as C a C 0 3) and passed through a particulate filter, ultraviolet
sterilizer, and activated carbon.
Dilution water chemistry:
Hardness:
176 mg/L as C a C 0 3

004GS4
Stock and test solution preparation: Test solutions were created by direct
weights addition. Exposure vessels: 300 mL glass beakers containing 250 mL test solution (9
cm depth). Number of replicates: two Number of daphnids per replicate: 10 Number of concentrations: five plus a blank control Water chemistry during the study:
Conductivity range: (0-48 hours) 610 - 620 pmhos/cm (control exposure) 710 - 720 pmhos/cm (2000 mg/L exposure)*
pH range (0-48 hours): 8.2 - 8.3 (control exposure) 8.1 - 8.2 (2000 mg/L exposure)*
Temperature range (0-48 hours): 20.4 - 20.7 C (control exposure)
20.3 - 20.8 C (2000 mg/L exposure)* Dissolved oxygen range (0-48 hours):
8.1 - 9.1 mg/L (control exposure) 8.1 - 9.1 mg/L (2000 mg/L exposure)* * 2000 mg/L (second highest concentration) exposure values used because the highest concentration used resulted in total mortality by
48 hours.
RESULTS___________________________________________________
Element values:
24-hour EC50 = 1790 (1550 - 2070) mg/L 48-hour EC50 = 1200 (730 - 2000) mg/L 48-hour NOEC = 730 mg/L
Element values based on nominal concentrations
Remarks: Testing was conducted on the mixture of the test substance as described in the test substance remarks field. The values reported apply to that mixture and not the test substance.
CONCLUSIONS___________________________________________________
The FC-1015 48-hour EC50 was determined to be 1200 mg/L with a 95% confidence Interval of 730 to 2070 mg/L. The 48-hour No Observed Effect Concentration was 730 mg/L

III. SUMMARX
Tha acuta toxicity oi rc-1015 to tha daphnid, Daphnla magtta, is described in thia final report. Tha taat waa conducted for 3H Company for 48 hour from April 16 to 18, 1996, at t .r . wilbury Laboratories, Inc. in Marblahaad, Haaaacbuaatta. It waa conducted by Jacqualine Nevius, Jeanne Magazu, Keven stavana, Patar Kowalski, Robert Boari, and Timothy Hard according to tha proceduraa of tha 0.S. Environmental Protection Agency (1993). PC-1015 waa auppliad by tha sponsor.
Tha teat waa performed under atatic conditiona with five
concentrations of teat substance and a dilution water control at a
temperature of 20.2 to 21.0*C. The dilution water was filtered deionized
water collected at Marblehead, Massachusetts and adjusted to a hardness of
.176 mg/L as CaCO}. y-v .
' ...y:.
Nominal concentrations of FC-1015 were 0 (control), 430, 730, 1,200, 2,000, and 3,330 mg/L. 'Daphnids used in tha test were less than 24 hours old at tha start of the test. They were produced at T.R. Nilbury Laboratories and acclimated under test conditions for their entire life (cultures that produced test specimens were maintained at test conditions for store than 7 days). After 48 hours of exposure the control daphnids had an average wet weight (blotted) of 0.35 mg. All daphnids were in good condition at the beginning of the study.
Exposure of daphnids to FC-1015 resulted in a 48 hour median lethal concentration (LC50) of 1,550 mg/L (95% confidence interval 1,200 to 2,000 mg/L) and a 48 hour median effective concentration (EC50) of 1,200 mg/L (95% confidence interval - 730 to 2,000 mg/L). The 48 hour no observed effect concentration (NOEC) is 730 mg/L.

TEST SUBSTANCE !
The sample of FC-1015 (T.R. Wilbury Laboratories Sample Number 604)
was delivered to T.R. Wilbury Laboratories on April 4, 1996. The sample was delivered in a metal can within a cardboard box at ambient di;
A
temperature. The test substance was contained in 1 250-ml plastic bottle
The label attached to the bottle contained the following informations "PC- ^

The toxicity test was performed according to tha procedures of tha
O.S. Environmental Protection Agency (1993). A summary of tha taat system

A screening test was not conducted because nominal concentrations '
for the definitive test were provided by the sponsor.^ The'definitive taat
was performed.from April 16 to 18, 1996 with five concentrations of teat
substance and a dilution water control. Nominal concentrations of EC-1015
were 430, 730, 1,200, 2,000, and 3,330 mg/L. Appropriate>.amounts'of.test
