Applicant's summary and conclusion
- Conclusions:
- The percent distribution was 81.4% to soil, 18.3% to water, 0.19% to sediment, and 0.05% to air.
- Executive summary:
Distribution was calculated according to Mackay, Level III, using equal emissions to air, water, and soil. The percent distribution was 81.4% to soil, 18.3% to water, 0.19% to sediment, and 0.05% to air.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
