DETERMINATION OF DEAD TIME
- Method: An internal standard (formamide) with no retention on the HPLC column was used to determine the deadtime of the HPLC system.
REFERENCE SUBSTANCES
- Identity: Acetanilide, Nitrobenzene, Naphthalene, 2-Methylnaphthalene, Anthracene, DDT
REPETITIONS
- Number of determinations: 2
EVALUATION
- Calculation of capacity factors k': The adsorption coefficient is deduced from the capacity factor (k) given by: k = (tr-t0)/t0, where tr is the measured retention time of sample or reference and t0 is the retention time of the internal deadtime standard.

- The test substance was found to have a log10Koc value of 3.0 at 25 ºC.
- Executive summary:
The adsorption coefficient of BMI was determined using the HPLC method according to EC C.19, OECD 121, and GLP principles. The log10Koc value was determined to be 3.0 (equivalent Koc value of 970) at 25 ºC.

Description of key information
The log Koc of the substance was determined to be 3.0.
Key value for chemical safety assessment
- Koc at 20 °C:
- 970
Additional information
A soil adsorption coefficient study was conducted in compliance with GLP and the soil adsorption coefficient determination and was performed according to OECD test guideline 121 and EC method C.19. The soil adsorption coefficient was determined by the HPLC method. The soil adsorption coefficient of BMI was determined to be log Koc: 3.0 (equivalent Koc: 970) at 25ºC. The Koc is 1000 at 20°C. Substances with log Koc > 4 are generally regarded as highly adsorptive and likely to distribute in sediment and soil.
