Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The fraction of organic carbon contained in the sample of sediment were ca. 1.5 %. 
A Kd of 0.013 was observed for o-toluidine, therefore the Koc can be calculated to 0.87. 
These results indicate a low sorption potential of o-toluidine onto the organic phase of soil or sediments.
