Results and discussion

Transformation products:
yes
Details on transformation products:
Biotransformation of 2,4-Dichlorotoluene (2,4-DCT) and 3,4-DCT resulted predominantly in the formation of
4-chlorotoluene (the metabolites 2-CT and 3-CT, respectively, occurred at minor concentrations).
Further dechlorination of 4-CT was evident from toluene formation.

Degradation products: yes
Degradation products (CAS No./EC No./EINECS Name): 106-43-4 203-397-0 4-chlorotoluene
Degradation products (CAS No./EC No./EINECS Name): 108-88-3 203-625-9 toluene
