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
