From thhis, it can be concluded that emissions to the water compartment remain in this compartment (with partitioning to sediment) whilst emissions to soil distribute primarily to soil and water and emissions to air distribute to all three compartments
Applicant's summary and conclusion
- Conclusions:
- Worse case environmental concentrations in water and soil are predicted to be below 0.7mg/l and air less than 0.1ppb assuming all material produced is emitted to the environment.
- Executive summary:
Mackay fugacity modelling (level 3) indicates that, taking into account degradation and using inflow parameters which are consistent with the known production tonnage of this substance in Europe, environmental concentrations under worse case emission conditions in water and soil are predicted to be below 0.4mg/l and 0.075mg/kg respectively and air less than 0.1ppb. This can be considered a worse case prediction as it assumes all product is emitted to atmosphere with no emission control systems used.
