Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Results and discussion

Any other information on results incl. tables

A level I fugacity model was used to assess the distribution of 1,3-butadiene when released into the environment (Exxon Biomedical Sciences: US EPA, 1991). This type of modelling assumes equilibrium partitioning and no advection. The results showed that the vast majority (99.97%) would be found in the air compartment.
