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 13670 L/kg (log Koc= 4.1359) by means of MCI method at 25 deg. C.  This log Koc value indicates that test chemical has strong sorption to soil and therefore test chemical has negligible to slow migration potential to ground water.

Additional information

Adsorption/desorption:

Predicted data study and experimental studies have been reviewed for adsorption endpoint of 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 13670 L/kg (log Koc= 4.1359) by means of MCI method at 25 deg. C.  This log Koc value indicates that test chemical has strong sorption to soil and therefore test chemical has negligible to slow migration potential to ground water.

Next study was experimental study reviewed from authoritative database in this the adsorption coefficient (Koc) value was calculated using astructure estimation method based on molecular connectivity indices. The adsorption coefficient (Koc) value of test substance was estimated to be 4800000 (Log Koc = 6.6812). This Koc value indicates that the test chemical has a very strong sorption to soil and sediment and therefore has negligible migration potential to ground water.

Another study was also experimental study reviewed from same source mentioned above in this the adsorption coefficient (Koc) value was calculated using astructure estimation method based on molecular connectivity indices. The adsorption coefficient (Koc) value of test substance was estimated to be 10000 (Log Koc = 4.0).

By considering all the studies mentioned above Log Koc value of test chemical is expected to be in range of 4.0- 6.68 dimensionless. This range log Koc value indicates that the test chemical has a strong sorption to soil and sediment and therefore have negligible to slow migration potential to ground water.
