Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Shanaker et al., 1985 studied biodegradation of three phthalic acid esters including DBP in a garden soil. The soil microflora was able to degrade actively complete DBP up to concentration of 0.472 mg DBP/kg soil under aerobic condition within 15 days. There were observed no degradation of DBP in the autoclaved control. NOEC 15d (or 30d) was 0.472 mg of DBP /kg soil. Anaerobiosis created by flooding greatly retarded the degradation of the DBP

Key value for chemical safety assessment

Additional information

The value was not used for PNEC estimation because the study is not a typical ecotoxicology study and only one concentration of DBP was tested.
