Description of key information

A BSAF value of <1 indicates a lack of bioaccumulation.

Key value for chemical safety assessment

Additional information

Data to assess the potential for terrestrial bioaccumulation of DIDP were reported in a 14-day earthworm (Eisenia fetida) toxicity study. The biota-soil accumulation factor (BSAF) as measured in a natural soil was 0.015 based on a DIDP concentration in the earthworm of 120 mg/kg (wet weight) and in soil of 7829 mg/kg (dry weight). A BSAF value of <1 indicates a lack of bioaccumulation. DIDP is an analog to DIUP therefore these data suggest that DIUP will also exhibit an equally low potential to bioconcentrate.
