Reference
Endpoint:
phototransformation in air
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Guideline:
other: calculation
Key result
Reaction with:
OH radicals
Rate constant:
0 cm³ molecule-1 s-1

The result translates to an atmospheric half-life of 13.8 days using an average atmospheric hydroxyl radical concn of 5X10+5  molec/cu-cm (HSDB).

Validity criteria fulfilled:
yes
Conclusions:
The calculated value for the reaction rate due to OH radical degradation in the atmosphere is reported to 1.16E-12 cm3/molecule-sec.
Executive summary:

Although the calculation method is not reported, the data were taken from a peer-reviewed database and are thus considered to be reliable with restrictions
