Applicant's summary and conclusion
- Conclusions:
- The chemical 3,7-dimethylocta-2,6-dienenitrile is not persistent in air medium as the half life period of 3,7-dimethylocta-2,6-dienenitrile in air is 0.023 day which does not exceed the criteria of 2 days.
- Executive summary:
The atmospheric oxidation half-life of 3,7-dimethylocta-2,6-dienenitrile was estimated using the level III multimedia model. It was estimated that the substance is not persistent in air medium as the half life period of 3,7-dimethylocta-2,6-dienenitrile in air is 0.023 days. This indicates that 3,7-dimethylocta-2,6-dienenitrile is photo transformed in air.
