Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

As no more information is available on the effects of DBP on higher organisms other than laboratory mammals, the overall oral LOAEL of 52 mg/kg bw (see Section Toxicity for reproduction) will be used for the derivation of the PNEC for predators.

Key value for chemical safety assessment

Additional information

According to EU RAR for DBP, 2004 there are some tewsts with birds such a study by Peakall, 1974, who examined the effects of a diet of 10 mg DBP/kg on egg shell thickness, breaking strength, permeability and shell structure of ring dove (Streptophelia risoria) eggs in a 3-week experiment and egg shell thickness was found to be decreased (10%), whereas the water permeability increased (23%). A 15% decrease in shell thickness is considered significant for reproductive effects. Rapid recovery occurred upon cessation of exposure. The second was provided by Korhonen et al., 1983, where an ED50 of 33 μmol (9.19 mg) per egg was calculated for DBP in a chicken embryo toxicity study.
