TGIC is inherently biodegradable when tested in municipal sewage sludge bacteria. 1 - 48 % of the substance is bio-degraded in several test. The large variability of the results is not explained, but may be connected with the low solubility if TGIC in the salt solution required for these tests. Although, biodegradation in soil and sediment has not been experimentally tested, the biodegradation half-live can be deduced from that in water with some uncertainty. We have taken the same value for soil and sediment as for water for the following reasons: Detoxification of TGICoccurs mainly through hydrolysis (with a half-life in water = 6.6 days) and detoxification is the main issue , not degradation. Even if biodegradation takes a long time (> 60 days in certain compartments), due to its physico-chemical properties it will not bioconcentrate, and cause adverse effects. The fully hydrolized TGIC is no longer toxic, and even if degradation takes some time, it causes no danger to the environment.
