Any other information on results incl. tables

Based on the identified uses as well as the intrinsic properties of Benzoguanamine direct emissions to the air and the soil compartment can be neglected. Thus, for simulation only emissions to water have been considered (1000 kg/hr).

Applicant's summary and conclusion

Conclusions:
The Mackay-III-simulation gives clear indication that the water is the major compartment of concern with view to the emission pattern based on the identified uses.
