estsvestnee ACTIVATED SLUDGE RESPIRATION INHIBITION TEST TEST SUBSTANCE
Identity: Perfluorooctanesulfonyl fluoride; may also be referred to as POSF, or FX-8. (1-Octanesulfonyl fluoride, 1,1,2,2,3.34,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-, CAS #307-
35-7).
wewo Remarks: The test substance is a clear liquid of uncharacterized purity. Itis described as FX-8 (ccB42-2) washed sample.
METHOD
Method: Protocol Reference EAR/WAS 5/9/84 Test type: Not noted. GLP: No Year completed: 1984 Analytical monitoring: Dissolved `oxygen concentrations. Stock and test solution preparation: Test substance (0.309 g) weighed directly into BOD bottle, 50 mL deionized water was added, and the bottle mixed on a magnetic mixer for ~ 30-minutes. Bottle was cappedduring
Inoculum source: Activated sludge mixed liquor from the Metro `wastewater treatment plant -- St. Paul/Minneapolis, MN. Inoculum holding: None - used the day it was obtained. Element basis: Respiration inhibition as determined by oxygen
consumption.
ews Method remarks: After mixing in the BOD bottle, it was noted that the sample settled to the bottom, forming small droplets or beads. Some of the sample appeared to emulsify. RESULTS
Nominal concentrations: 1000 mg/L test material solution.
Element value:
6.75-min ICso = > 1000 mg/L
covwsows Control response: Adequate -- 6.5% difference in respiration rateof the
two controls. CONCLUSIONS
The test material exhibited no inhibitory effect at 1000 mg/L ovear 6.75minute exposure.
