Applicant's summary and conclusion
- Conclusions:
- The adsorption coefficient of A-88820.605 was estimated by calculation using 3 different methods:
a) Kenaga/Goring correlation (1980) 0.544 Log Pow + 1.377 = Log Koc = 1.63 b) Hodson/Williams correlation (1988) 0.827 Log Pow + 0.292 = Log Koc = 0.68 c) Computer calculation 'Estimation of the soil adsorption coefficient Koc, version 1.21, Syracuse Research Corporation gives Log Koc = 4.86 For the computer program, the value is for the free amine not the salt
