Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Calculation was performed according to the model described in the first publication of Mackay (1991). Phase properties and composition of the compartments were modified as suggested by the Federal Environmental Agency (UBA, Germany).

Applicant's summary and conclusion

Executive summary:

The distribution of p-chlorotoluene in a "unit world" was calculated according to the Mackay fugacity model level I (Bayer Industry Services, 2004) based on the physico-chemical properties. The main target compartment for p-chlorotoluene is air with 99.67 %, followed by water with 0.24 %, and soil with 0.04%.
