Description of key information

In the test conditions, Raphanus sativus does not bioaccumulate DBP (BCF < 1) when introduced in soil via sludge amendment.

Key value for chemical safety assessment

BCF (terrestrial species):
1 dimensionless

Additional information

Cai et al. (2008) studied the uptake of 5 polycyclic-aromatic hydrocarbons and 2 phthalic acid esters (including DBP) in radish (Raphanus sativus). Seeds were grown in lactosolic red soil free of contamination and in soil amended with 1, 2 or 4 % of sewage sludge containing a mix of all these organic contaminants.

Sludge contained 3.7 mg/kg dw of DBP. Plants were grown during 64 days before harvest. Concentration of DBP in plant (shoot and roots separately) and in substrates, have been measured after harvest with GC-MS method and BCF were deduced from these concentrations. In roots or in shoots, and whatever the concentration in DBP in substrate, the BCFs were < 1.
