From: A weight-of-evidence approach to assess chemicals: case study on the assessment of persistence of 4,6-substituted phenolic benzotriazoles in the environment

Fig. 3

Simulated simplified mechanisms for the degradation of the phenolic benzotriazoles. a Degradation of the benzotriazole moiety, b degradation of side chain R2 and c degradation of side chain R1 leading to the ring cleavage of the phenolic ring R1, R2: alkyl; R3: H or Cl. Side reactions are for the sake of simplicity not considered here. Simulation was done using the EAWAG-BBD Pathway Prediction System [43]
