Results and discussion
Any other information on results incl. tables
Solids-water partitioning coefficient of 158.5 l/kg (log value 2.2).
This value was determined. this value was used in the RA Zinc because it is based on the part of the metals that can actually exchange and is to be assumed in equilibrium with the water phase.Furthermore, experimental values were considered more reliable than field-based , in the RA.
Applicant's summary and conclusion
- Conclusions:
- Tests of good quality and considered useful for assessing the effect on the endpoint. Result used in the RA zinc (ECB 2008)
- Executive summary:
A solids-water partitioning coefficient of 2.2 (log value) was determined experimentally on 11 American soils. This value was used in the RA Zinc because it is based on the part of the metals that can actually exchange and is to be assumed in equilibrium with the water phase.Furthermore, experimental values were considered more reliable than field-based, in the RA.
