Applicant's summary and conclusion

Validity criteria fulfilled:
not specified
Conclusions:
Phenylacetonitrile is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals. The half-life for this reaction in air is estimated to be 7.8 days, calculated from it's rate constant of 2.1E-12 cu cm/moluce-sec at 25°C that was derived using a structure estimation method.
Executive summary:

According to the peer reviewed database phenylacetonitrile is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals. The half-life for this reaction in air is estimated to be 7.8 days, calculated from it's rate constant of 2.1E-12 cu cm/moluce-sec at 25°C that was derived using a structure estimation method.
