Description of key information
The adsorption coefficient (logKoc) of the test item is 4.6, measured at 25 °C and pH 6.
Key value for chemical safety assessment
- Koc at 20 °C:
- 39 811
Additional information
For the determination of the adsorption coefficient (Koc) four calibration standards with log Koc from 2.31 - 4.20 are established in the EG-test method. Additional a new reference substance 9,10-Dimethyl-1,2-benzanthracene (7,12-Dimethylbenzanthracene) was used in this test. The experimental value of log Koc = 5.37 for 9,10-Dimethyl-1,2-benzanthracene was published by Donald A. Bahnick and William J. Doucette in the “Chemosphere, Vol. 17, No. 9, pp 1703-1715, 1988”. Although the determined value does not exactly meet the range of application of the test guideline (1.3 – 5), the value is considered as valid (measurement uncertainty +/- 0,5 log units).
[LogKoc: 4.6]
