EC number: 700-202-5
CAS number: 765-63-9
The measured concentrations of TFO ranged between 39 and 63% of their
nominal values in freshly prepared media and between 41 and 69% of their
nominal values in samples of expired (24-hour-old) media (between 101
and 110% of the starting values). Although precautions were taken to
minimise losses via volatilisation during the preparation of the test
media, the values achieved were considered acceptable given the nature
of the test substance. As the levels achieved were maintained throughout
the test, the use of a sealed test system was considered successful.
After 48 hours, the lowest measured concentration at which 100%
immobility occurred was 5.05 mg/L and the highest concentration at which
no immobilisation was noted was 2.13 mg/L.
