Description of key information

Soil Adsorption Coefficient  i.e Koc value of phthalylsulfathiazole was estimated as 685.1  (log Koc : 2.8357) at 25 deg C by means of MCI method.

Key value for chemical safety assessment

Koc at 20 °C:
548.08

Additional information

Soil Adsorption Coefficient i.e Koc value of phthalylsulfathiazole was estimated as 685.1 (log Koc : 2.8357) at 25 deg C by means of MCI method. This indicates that phthalylsulfathiazole will moderately adsorb to the organic carbon fraction of the soil and will have a slow migration potential to groundwater. The key value of Koc at 20 deg C is equivalent to 548.08 (log Koc :2.7388 )

[LogKoc: 2.7388]
