Description of key information

Reactive Orange 136 can be regarded as little mobile in soils.

Additional information

The adsorption and desorption of FAT 45'176/A were determined in a screening test by the batch equilibrium method using three soils: Speyer (loamy sand), Les Barges (silt loam) and Sisseln (sandy loam) under GLP compliance and used as the key study. The result showed the KOC values were 1105 ml/g, 1156 ml/g and 1249 ml/g for soils, Sissein and Les Barges, respectively. FAT 45'176/A can therefore be regarded as little mobile in soils.

An average KOC value of 1170 is taken forward for hazard and risk assessment
