AR506-O3SI MICROBIOS MICROTOX TOXICITY TEST TEST SUBSTANCE Identity: Perfluorodecanesulfonate, ammonium salt; may also be referred to as PFDS, FC-121-X, or 3M Sample E2112 and E2566-1. (1Decanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heneicosafluoro-, ammonium salt, CAS # 67906-42-7) Remarks: Test sample is a mixture of the test substance in water and 2propanol, 1-(1,1-dimethylethoxy). This mixture contains approximately 2226% test substance, 33-37% propanol, 1-(1,1-dimethylethoxy), 0.5-1.5% perfluorononanesulfonate, ammonium salt and 38-42% water). All values reported relate to this mixture. No calculations were made to adjust for the actual concentration of the test substance in the test sample. Test material was from 3M production lot 1. Note: Only the summary page was available for this study METHOD Method: Microbios Microtox Procedure Test type: Static acute GLP: No Year Completed: 1987 Species: Photobacterium phosphoreum Analytical monitoring: None Statistical methods: Microbios computer software package Test organism source: Microbics Microtox Reagent Test conditions: Per Microbics method Replicates: Two RESULTS Nominal concentrations: 125, 250, 500, 1000 mg/L Test Sample Element values: 5-minute EC50 =640 (605-670)) mg/L 15-minute EC5q=290 (260-310) mg/L All element values based on nominal concentrations. CONCLUSIONS FC-121 exhibited a 15-minute EC5ofor Photobacterium phosphoreum of 290 mg/L with a 95% confidence interval of 260- - 310 mg/L. 000211 Testing was conducted on the "as-sold" mixture of the subject material in water (~22 - 26% subject material). The values reported apply to that mixture and not directly to the subject material. Submitter. 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY Reliability: : Klimisch ranking 4. Most of the supporting material for this study is missing. Because a mixture was tested, care must be taken when interpreting the results. The solvent in the mixture could have enhanced or restricted biological uptake and/or toxicity of the fluorochemical component.
