ACUTE TOXICITY TO AQUATIC INVERTABRATES (DAPHNIA MAGNA)
IESTSUBSTANC 0E 0
Identity: A mixture containing perfluorooctanesulfonate, which may also
be referred to as PFOS, FC-95, or as a component of FC-600. (1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8heptadecafluoro-, potassium salt, CAS # 2795-39-3)
Remarks: The 3M production lot number was not noted. The test
sample is FC-600 (2-15-77 RAW). Current information indicates it is a mixture of 1.0% PFOS, 81.20% water, 12.00% diethylene glycol butyl ether, 1.00% sodium octyl sulfate, 2.00% propane Sultone foamer, 1.00% sodium decyl sulfate, 0.85% xanthan gum, 0.1% N-(3-chloroallyl)
hexaminium chloride, 0.80% starch, and 0.05 %-benzotriazole.
The following summary applies to a mixture with incompletely
characterized concentration of impurities. Data may not accurately reflect the toxicity of the fluorochemical component of the test sample.
This study is the first of 3 daphnia studies conducted to determine the
toxicity of FC-600 after being treated through a SCAS reactor. There is no synthetic sewage medium present.
