Applicant's summary and conclusion

Executive summary:

INDIRECT PHOTOLYSIS in water OH radical induced indirect photolysis of C20/22 ATQ in air can be estimated with US EPA AOPWIN Program estimating low degradation half-lives (C20 homologue 9.7h, C22 homologue 9h). Therefore C20/22 ATQ may also be degraded in water by indirect photolysis if sufficent OH radicals were available.
