Description of key information

The absorption coefficient (Koc) of PX-200 has been determined to be greater than 4.21x10-5, log10Koc > 5.63.

Key value for chemical safety assessment

Koc at 20 °C:
4.21

Additional information

The soil adsorption has been measured by HPLC according to EU Method C.19.

Greater than 4.21 x 105, log10Koc> 5.63, using the OECD draft document (DEcember 1998): Estimation of the Adsorption Coefficient (Koc) on Soil and Sewage sludge using High Performance Liquid Chromatography (HPLC).

[LogKoc: 5.63]
