- Rationale for reliability incl. deficiencies:
- accepted calculation method
- GLP compliance:
- not specified
- DT50:
- 3.9 d
- Remarks on result:
- other: estimation of hydrolysis in the clouds using Henry's law constant = 20 M.atm-1 and unimolecular hydrolysis rate k(H)= 8 sec-1 from George et al., 1993.
- Remarks:
- 'Heterogeneous removal process)
- Conclusions:

- Endpoint:
- phototransformation in air
- Type of information:
- experimental study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Principles of method if other than guideline:
- - Principle of test:
the tropospheric lifetime of halides was estimated from their dissolution potential in the aqueous phase
- Short description of test conditions: experimental phase was conducted at various pH and temperatures
- Parameters analysed / observed: determination of the Henry's law solubility (H) and hydrolysis rate (Khyd) and product H*khyd - GLP compliance:
- not specified
- Estimation method (if used):
- PHOTOCHEMICAL REACTION WITH OH RADICALS: Not used, it is predicted to be negligible
- DT50:
- >= 5 - <= 10 d
- Test condition:
- Estimated minimum lifetime from tropospheric cloud processing. Determined at 278K.
- Remarks on result:
- other: Using Henry's constant of 1 M/atm. as maximum value
- Reaction with:
- other: cloud liquid water
- Remarks on result:
- other: khyd: > 5 and <500 sec-1
- Conclusions:
- The tropospheric lifetime of Carbonyl fluoride derived from in cloud heterogeneous removal was estimated to be 5-10 days.
The tropospheric lifetime for COF2 was determined to be 0.5 - 3 days, using hydrolysis rate range 5 < khyd < 500 sec-1 and at a temperature of 278K.
Whend considering cloud formation probabilities, the lower limit for the lifetime would be 5 -10 days.
