Description of key information

The Adsorption Coefficient, log Koc of MBB (extrapolated) was 0.75 (KOC: 5.64) and 0.82 (KOC: 6.63) for soil and sewage sludge respectively.

Key value for chemical safety assessment

Koc at 20 °C:

Additional information

The Adsorption Coefficient of MBB was determined following OECD 121 (Estimation of the Adsorption Coefficient (KOC) on Soil and on Sewage Sludge) using High Performance Liquid Chromatography (HPLC)).

The Adsorption Coefficient, log KOC of MBB (extrapolated) was 0.75 (KOC: 5.64) and 0.82 (KOC: 6.63) for soil and sewage sludge respectively.

MBB was hence classified as very high mobile in soil (KOC: 0-50), based on McCall classification scheme of soil mobility potential.
