CONCLUSIONS Texhpeostuesrte.material exhibited no inhibitory effect at 1000 mg/L over ~5.5 minute Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 oaAQUATY Reliability: Kiimisch ranking 3. The study lacks description and recordsofthe method followed. The inoculum is not properly characterized. There is no characterizationofthe test substance purity, and the study lacks analytical confirmationofthe amount of fluorochemical proportion in the solution. The testing was conducted on a mixtureofchemicals having varying degrees of biodegradability, leading to potential misinterpretationofthe results.
