Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Degradation Half-lives: 50% after 0.81 to 1.31 hr for the major components in the submission substance
- Executive summary:
Indirect photochemical degradation of the major components in the submission substance as mediated by OH-attack is estimated to have a half-life of 0.81 to 1.31 hrs based on a 12 hour sunlight day and an average OH- concentration of 1.5 x E+6 OH-/cm3. A 12-hour day half-life value normalizes degradation to a standard day light period during which hydroxyl radicals needed for photolysis are generated in the atmosphere. Although the submission substance has the potential to degrade rapidly by OH-attack, multimedia Level III distribution modeling indicates the test substance is predicted to partition negligibly (< 0.04%) to the air compartment because it has a low vapor pressure ( < 3.4 x E-4 Pa). Although the majority of the components in the submission substance has a relatively short atmospheric oxidation half-life (0.81 -1.31 hours), this process is unlikely to contribute significantly to the loss of test susbtance from the environment.
