Applicant's summary and conclusion
- Conclusions:
- According to the calculated distribution cinchonidine mainly retains to soil.
- Executive summary:
According to the fugacity model, Level III, the distribution of cinchonidine to air - water - soil - sediment is 0.00000988 - 9.57 - 80.4 - 10.1 %. These results show, that the majority retains in soil, while there are lower amounts available in air, water and sediments.
