A R B fc -0 5 6 ACUTE TOXICITY TO FISH TEST SUBSTANCE Identity: Perfluorooctanoic acid, ammonium salt; may also be referred to as PFOA ammonium salt, Ammonium perfluorooctanoate, FC116, FC-126, FC-169, orFC-143. (Octanoic acid, pentadecafluoro-, ammonium salt, CAS # 3825-26-1) Remarks: 3M production lot number 390. The test sample is FC-126, a white powdery solid. It's purity was not sufficiently characterized, though current information indicates it is a mixture of 78 - 93% test substance and 7 - 22% C5, C6, and C7perfluoro analogue compounds. METHOD: Method: Not stated Type: Static acute GLP: No Year com pleted: 1987 Species: Pimephales promelas Supplier: Dale Fattig of Brady, Nebraska. A nalytical m onitoring: Temperature, pH and DO Exposure period: 96-hours S tatistical methods: Probit analysis Test fis h age: Not noted. Length and weight: Average length = 3.5 cm Average weight = 0.30 g Pretreatm ent: None. Test conditions: D ilution water: Carbon-filtered well water. D ilution water chem istry (initial): Temperature: 21 C Dissolved Oxygen: 9.3 ppm pH: 7.9 Stock and test solution preparation: Test solutions were created by direct weights addition. Concentrations dosing rate: Once S tability o f the test chemical solutions: Not noted Exposure vessels: 4 liter Pyrex glass beakers containing 3 liters test solution. Number o f replicates: two Number o f fish per replicate: 6 Loading rate: 0.60 g/L Number o f concentrations: five plus a blank control 003869 W ater chem istry during the study: Dissolved oxygen range (24 - 96 hours): 6.6 - 7.4 mg/L (control exposure) 5.6 - 6.6 mg/L (320 mg/L exposure)* pH range (24 - 96 hours): 7.7 - 7.9 (control exposure) 7.7 - 8.0 (320 mg/L exposure)* * 320 mg/L test group (third highest concentration) data given because total mortality occurred in the two higher test concentrations by 24 hours. Test tem perature (24 - 96 hours): 20C RESULTS Nominal concentrations: Bk control, 100, 180, 320, 560, and 1000 mg/L Element value: 96-hour LC50 = 301 (244 - 370) mg/L Element value based on nominal concentrations CONCLUSIONS The test sample 96-hour LC50for fathead minnow was determined to be 300 mg/L with a 95% Confidence Interval of 240 to 370 mg/L. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY Reliability: Klimisch ranking 2. Testing meets the criteria for quality testing. However, sample purity was not properly characterized and it lacks analytical confirmation of test substance concentrations.
