Additional information

The adsorption coefficient (Koc) on soil and on sewage sludge using high performance liquid chromatography (HPLC) has been estimated and adsorption coefficients estimated to be log Koc,soil = 2.34 and log Koc, sewage sludge = 2.39.

These values correspond to a Koc,soil = 217 and Koc,sewage sludge = 245.

The McCall classification scheme classifies the substance as having medium mobility in soil (Koc 150 - 500).

The Henry's Law constant was estimated using the software HENRYWIN (v3.20). The value of 0.0256 Pa m³/mol indicates that the substance is essentially not volatile from surface water.

.

Distribution in environmental compartments has been calculated using a Fugacity model according to Mackay, Level III. Distribution in various environmental compartments is estimated as: Air= 1.95%; Water= 22.1%; Soil= 75.7% and Sediment= 0.224%. Soil and water were then found to be the major target compartments.
