Materials and methods

Test guideline
Qualifier:
according to
Guideline:
EU Method C.19 (Estimation of the Adsorption Coefficient (KOC) on Soil and Sewage Sludge Using High Performance Liquid Chromatography (HPLC))
GLP compliance:
yes (incl. certificate)
Media:
soil/sewage sludge

Test material

Name:
Unnamed
Type:
Constituent

Results and discussion

Adsorption coefficient
Type:
log Koc
Value:
> 4.09
Remarks on result:
other: pH values of solutions could not be determined as pH value is only defined for aqueous solutions, not methanolic solutions

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The retention time of the test item is higher than the retention time of the reference with the highest log Koc (Phenenthrene; log Koc = 4.09). Thus log Koc of the test item can be reported: Log Koc > 4.09
