Description of key information

Soil Adsorption Coefficient i.e Koc value of 2-aminobenzenesulphonic acid was estimated as 10 L/kg (log Koc=1) by means of MCI method. This indicates that 2-aminobenzenesulphonic acid will have a negligible tendency of sorption to soil and sediment and therefore have rapid migration potential to groundwater.This Koc value when converted at 20 degC is equivalent to 8.

Key value for chemical safety assessment

Koc at 20 °C:
8
