Results and discussion
Any other information on results incl. tables
Volatilization half-life in a model river (flow 1 m/sec) was calculated to 7.5 days, based on a water solubility or 12 g/l and a vapour pressure of 40 Pa at 20 °C (Henry's law constant: 0.59 Pa m3/mol). Based on a water solubility of 17.5 g/l, the volatilization half-life would be 11 days.
Applicant's summary and conclusion
- Conclusions:
- Volatilization half-life in a model river (flow 1 m/sec) was calculated to 7.5 days.
- Executive summary:
Volatilization half-life in a model river (flow 1 m/sec) was calculated to 7.5 days
