Element values: 48-hour ECso = >1000 mg/L Element values based on nominal concentrations. Remarks: Substance Testing was conducted on Remarks field. The values a mixture reported as described in the Test apply to that mixture and not the fluorochemical proportion alone. conclusions The test substance 48-hour ECso was determined to be >1000 mgiL, the highest concentration tested. No mortality was observed. Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY Reliability: Kiimisch ranking = 2.
