Applicant's summary and conclusion
- Executive summary:
Using a calculated Henry's Law Constant (HLC) of 6.83 Pa*m³/mol at 25 C (EPI Suite, program HENRYWIN, group contribution method), volatilization half-lives for diisotridecyl adipate of 4.27 and 236.1 hr (9.84 d) were estimated for a model river and a model lake, respectively.
