ACTIVATED SLUDGE RESPIRATION INHIBITION
TEST SUBSTANCE
Identity:Perfluorooctanoiaccid,ammonium salt;may alsobe referredtoas PFOA ammonium saltA,mmonium perfluorooctanoateP,FO, FC116, FC-126, FC-169,or FC-1 43. (Octanoicacid,pentadecafluoroammonium salt,CAS # 3825-26-1)
Remarks: The 3M productionlotnumber was 37. The testsample isFC143. It'psuritywas not sufficientclhyaracterizedt,hough currentinformation indicatesitisa mixtureof96.5 - 100% testsubstance and 0 - 3.5% C6, C7, and Cg perfluoroanalogue compounds..
