Description of key information

Adsorption/desorption:

The Soil Adsorption Coefficient i.e. Koc value of test chemical was estimated using EPI suite KOCWIN Program (v2.00) as 108600 L/kg (log Koc= 5.0357) by means of MCI method at 25 deg. C.  This log Koc value indicates that test chemical  has very strong sorption to soil and therefore test chemical has negligible  migration potential to ground water.

Additional information

Adsorption/desorption:

Different studies have been reviewed for Adsorption endpoint for test chemical and its read across chemical and their results are summarized below.

In first study the Soil Adsorption Coefficient i.e. Koc value of test chemical was estimated using EPI suite KOCWIN Program (v2.00) as 108600 L/kg (log Koc= 5.0357) by means of MCI method at 25 deg. C

In another study the Soil Adsorption Coefficient i.e Koc value of test substance was estimated using Adsorption Coefficient module (v12.1.0.50374) program as Koc 7334 dimensionless (log Koc= 3.9) at pH 7.

Last study was reviewed from authoritative database in this study the Koc value for test chemical estimated was 19000 dimensionless and log Koc is 4.9590.

By considering results of all the studies mentioned above it is concluded that log Koc value of test chemical can be in range 3.9- 5.03 this range log Koc value suggests that test chemical test chemical is expected to have very strong sorption to soil and sediment and therefore has negligible migration potential to ground water.
