Additional information

FC-770 was not detectably degraded in an OECD 310 (Headspace) assay (ready biodegradation).

This method is specifically designed for volatile, insoluble materials and is appropriate for this substance. The study included a toxicity control having both reference substance and FC-770, each in the same amounts used in positive controls or test flasks. No biodegradation was observed of FC-770 when tested alone. Assuming that all biodegradation in the toxicity control was due to the reference substance and none due to FC-770, the toxicity control was not significantly different than the positive control, and FC-770 had no inhibitory effect on biodegradation.
