Description of key information

Adsorption/desorption:

The Adsorption Coefficient of test chemical was determined as per the HPLC method (OECD Guideline-121). The Log Koc value was determined to be 3.307 dimensionless at 25°C. Thus based on the result it is concluded that the test substance has a moderate sorption to soil and sediment and therefore has slow migration potential to ground water.

Additional information

Adsorption/desorption:

The adsorption coefficient Koc in soil and in sewage sludge of test chemical was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 121 . The reference substances were chosen according to functional similarity with the test substance and calibration graph prepared.

The reference substances were 4-chloroaniline, 4-methylaniline, N methylaniline, 2-Nitrophenol, Nitrobenzene, 4-Nitrobenzamide, N,N-dimethylbenzamide, N-methylbenzamide, Benzamide, phenanthrene having Kocvalue ranging from 1.239 to 4.09. .The Log Koc value was determined to be 3.307 dimensionless at 25°C.

 

Thus based on the result it is concluded that the test substance has a moderate sorption to soil and sediment and therefore has slow migration potential to ground water.
