BIODEGRADATION
TEST SUBSTANCE
Identity:Perfluorodecanesulfonataem,monium salt;may alsobe referred toas PFDS, FC-120,or3M Sample J2905-1.(1-Decanesulfonic acid,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10heneicosafluoroa-m,monium saltC,AS # 67906-42-7)
Remarks: Test sample isa mixtureofthetestsubstanceinwaterand butylcellosolv(eappmximately25% testsubstance,37.5% butyl cellosolvaend 37.5% water).Allvaluesreportedrelatetothismixture. No calculationwsere made to adjustfortheactualconcentratioonfthe testsubstance inthe testsample. Testsample was from 3M production lot164.
METHOD
Method: EPA 405.1 Type: Aerobic GLP: No Year completed: 1991 Contact time:20 days Inoculum: Source ofinoculumnotrecorded
RESULTS
5-day carbonaceous BOD: 67,000 mg/kg
10-day carb'onaceous BOD: 600,000 mg/kg
20-day carbonaceous BOD: 720,000 mg/kg
COD:
1,000,000mg/kg
Remarks: This materialhas a perfluodnatedmoietyand a nonfluorinatemdoiety.Currentknowledge ofthesechemistriesuggeststhat allbiodegradationindicatedinthisstudyislikeldyue toreductionofthe non-fluodnatedmoiety,butylcellosolve.
Testingwas conducted on the"as-soldm"ixtureofthesubjectmaterialin water (-25% subjectmaterial)T.he valuesreportedapplytothatmixture and notdirectltyothe subjectmaterial.
