A biodegradation study (Yokohama Laboratory, Mitsubishi Chemical Safety Institute Ltd. (M.S.I.), 1996) was conducted to assess the ready biodegradability of MTF in water.

The study was conducted according to official test methods (Test Method Relating to New Chemical Substances, Kanpogyo No. 5, Yakuhatsu No. 615, 49 Kikyoku No. 392, 1974) and in compliance with GLP.

On the basis of oxygen consumption, the test material was found not to have degraded over the 28 -day monitoring period.

On this basis, MTF is considered not to be readily biodegradable. It was noted that residual test material concentrations in media had decreased over the monitoring period, however this was considered to have been due to volatilization.
