Results and discussion
- Quantum yield (for direct photolysis):
- 0.002
- Predicted environmental photolytic half-life:
- The estimates based on two different arithmetic models (GC-SOLAR and Frank & Klöpffer) by means of the resulting quantum yield and the light
absorption in a range of wavelengths relevant for the environment were well comparable when considering identical marginal conditions. "Environmental direct photolysis half-lives" of more than 95 days can be calculated for the test item.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Only very weak degradation of the test item was measured by HPLC-UV during the maximum irradiation period of 500 minutes in pure water. This indicated a high stability of the test item against direct photo-degradation in aqueous solution relative to other compounds irradiated under the
same study conditions.
However, this assessment does not consider any indirect mechanisms, which may enhance the photodegradation in natural water.
