Results and discussion

Any other information on results incl. tables

Based on a LogKow of 4.95 and mean measured Koc values of 15 l/kg for MAA, 34 l/kg for MMA and 2760 l/kg for i-BMA a Koc of 6400 was calculated for 2 -EHMA by regression analysis.

Applicant's summary and conclusion

Conclusions:
Based on a LogKow of 3.03 and mean measured Koc values of 15 l/kg for MAA, 34 l/kg for MMA and 2760 l/kg for i-BMA a Koc of 6400 was calculated for 2 -EHMA by regression analysis.
