Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Materials and methods

- other: other (calculation)
- Calculation programme:
- Generic environmental behaviour calculated using a 'Multiphase Non-Steady State Equilibrium' mathematical model [Version 1.5, based on the model described by Yoshida (1987,1988)]. This assumes intraphase mass transfer is fast and in equilibrium whereas the slower interphase transfer is kinetically controlled. Transfers within and between air, water, soil and sediment are considered.
- Media:
- air - biota - sediment(s) - soil - water

Results and discussion
Percent distribution in media
- Other distribution results:
- 2,4-TDI is not persistent and is distributed only close to the release point, where 99% is in the air (at 4.7*10(-13) mg/l). Concentrations in the air and soil halve beyond 60 km leeward of the release point.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
