Description of key information

No experimental data is available on the terrestrial bioaccumulation of Verdox. The BCF in earthworms was estimated with the equation from Jager (1998) which is incorporated in the EUSES model and is applicable to substances with a log Kow value ranging from 1-8: BCF worm = (Fwaterworm + Flipidworm*Kow)/RHOworm where Fwaterworm = 0.84, Flipidworm = 0.012 and RHO worm = 1000. Entering the log Kow value of 4.75 for Verdox results in a BCF earthworm of 676 L/kg w.w.
