EPIWIN predicts rapid volatilisation from water (half life of 51minutes in a river, 3.3 days in a lake).

Applicant's summary and conclusion

Conclusions:
EPIWIN predicts rapid volatilisation from water (half life of 51 minutes in a river, 3.3 days in a lake).
Executive summary:

The volatilisation half life has been calculated using a standard model and indicates that volatilisation from a waterbody will be rapid.
