RESULTS
-
Nominal concentrations: Two blank controls, 1, 10, 100, and 1000 mg/L
Element values: 48-hour ECso = >1,000 mg/L
Element values based on nominal concentrations Remards: Testing was conducted on a mixture as described inthe Test
Substance Remarks field. The values reported applytothat mixture and not
the fluorochemical proportion alone.
CONCLUSIONS
The FC-206CE 48-hour ECso Was determined to be >1000 mg/L. Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133
