Overall log10 Koc: In the range 3.95 to greater than 5.63
Adsorption coefficient: In the range 8.98E03 to greater than 4.27E05 - Validity criteria fulfilled:
- yes
- Conclusions:
- The adsorption coefficient (Koc) of the test item at pH 5.5 has been determined to be in the range 8.98E03 to greater than 4.27E05, log10 Koc in the range 3.95 to greater than 5.63. These values indicate that the test item will be immobile at pH 5.5.
- Executive summary:
The adsorption coefficient of FAT 36002/G TE has been determined to be in the range 8.98 x 103 to greater than 4.27 x 105, log10 Koc 3.95 to greater than 5.63, at pH 5.5, and in the range 8.96 x 103 to greater than 4.27 x 105, log10 Koc in the range 3.95 to greater than 5.63, at pH 7.2, using the HPLC screening method, designed to be compatible with Method C.19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001. These values indicate that the test item will be immobile in the pH range 5.5 to 7.2.
Reference
As the test item has estimated (ACD/Labs I-Lab 2.0) pKa’s of approximately 8.0 (1 x bromine, where the two OH groups are near to each other), and approximately 9.4 (1 x bromine, where the two OH groups are opposite each other), it was considered appropriate to perform testing at pH 5.5 (this section) and pH 7.2 (see Section 4.2). As the slope of the calibration curve for the reference standards showed good first order correlation and as the retention times between duplicate injections for each solution was consistent, the HPLC method was considered valid for the determination of adsorption coefficient. Based on the chromatographic data, the test item was considered to be stable during the test procedure.
Description of key information
The adsorption coefficient (Koc) of the test item at pH 5.5 has been determined to be in the range 8.98E03 to greater than 4.27E05, log10 Koc in the range 3.95 to greater than 5.63. These values indicate that the test item will be immobile at pH 5.5.
