- Analytical monitoring:
- yes
- Details on sampling:
- Reference substances included acetanilide, aniline, benzamide, benzoic acid phenyl ester, 2,5-dichloroaniline, 4-nitrobenzamide, phenanthrene, and urea. Reference stock solutions were prepared by weighing the following amounts of each references substance into individual 10-mL volumetric flasks and diluting to volume with methanol. The stock solutions were sonicated as necessary to dissolve the reference substances. Three combined calibration solutions were prepared by transferring aliquots from each of the reference stock solutions in three 10-mL volumetric flasks. Standard solutions were diluted to volume with 55%/45% methanol/water. Segregation of reference substances was determined to avoid potential retention time overlap. Aliquot size was determined to control peak height. The test substance was prepared by weighing 38.9 mg of the test substance into a 10 mL volumetric flask and diluting to volume with 55%/45% methanol/water. The calibration standards and samples preparations were analyzed in triplicate by liquid chromatography with ultraviolet spectroscopic detection.

- yes
- Conclusions:
- Log Koc: Soil (1.08), Sludge (1.10)
Koc : Soil (12.0), Sludge (12.6)
This study and the conclusions which are drawn from it fulfill the quality criteria (validity, reliability, repeatability). - Executive summary:
Estimates of the adsorption coefficient (Koc) for the test substance on soil and sludge were established employing methodology described in the OECD Guidelines 121: Estimation of the Adsorption Coefficient (Koc) on Soil and Sewerage Sludge using High Performance Liquid Chromatography. The Koc and log Koc for soil were 12.0 and 1.08, respectively. The Koc and log Koc for sludge were 12.6 and 1.10, respectively.
