Distribution:
Air: 1.71 E-6%, water: 0.00347%, soil 99.8%, sediment 0.157%
STP fugacity model 10000 Bio P.A.S, temp. 25deg. C): Total removal: 94.03% total biodegradation: 0.78%.

Applicant's summary and conclusion
- Conclusions:
- When released into the environment the substance is predicted to mainly distribute to soil and sediment. In sewage treatment plants it is expected to be eliminated via adsorption to sludge.
