BIODEGRADATION (BOD/COD)
TEST SUBSTANCE
Identity:A mixturecontainingperfluorooctanesuftnatew,hich may alsobe referredtoas PFOS, FG-95, oras a component of L-4647. (1Octanesulfoniaccid)(CAS # 2795-39-3).
Remarks: The testsample is1.356% solutionofL-4647. Current informationindicatesitisa mixtureof6.6% PFOS, 20% polyethyleneglycol, 20% hexahydricalcohol,39% sodium decylsulfate1,3.2% Hydroxy foamer, 1% sodium ethylhexylsulfate0,.1% niethylhydroquinonea,nd 0.1% biphenylols,odium salt,tetrahydrate.
The followingsummary applies toa mixture with incompletely charactedzed concentrations of impudties. Data may not accurately reftct the biodegradabilityof the ffuorochemical component of the test
sample.
METHOD:
Method: BOD protocol3/10/80. Type: Aerobic GLP: No Year completed: 1980 Contacttime:20 days lnoculum: Chemolitesewage.
