Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Call et al., 2001 exposed the freshwater invertebrates Chironomus tentans and Hyalella azteca for 10 days (short-term) to DBP-contaminated sediment. Sediment contained 2.45%, 4.8% and 14.1 %TOC. The 10-d LC50 values for DBP and H. azteca were:17,400. 29,500, and.71,900 mg/kg dry weight for the low, medium, and high TOC sediments, respectively. The 10-d LC50 values for DBP and C. tentans were 826, 1,664, and 4,730 mg/kg dry weight for the low, medium, and high TOC sediments, respectively.
Effects of DBP on macrobenthic animals that colonized sand-filled boxes for 8 weeks in the laboratory and in the field were determined by comparing community structures in boxes that contained uncontaminated and DBP-contaminated sand by Tagatz et al., 1986.
In the exposure (both field and laboratory tests) via sediment (nominal), no significant effects occurred at 100 mg/kg, and echinoderms and molluscs were the only phyla affected at 1000 mg/kg.
Key value for chemical safety assessment
- EC50 or LC50 for freshwater sediment:
- 826 mg/kg sediment dw
- EC10, LC10 or NOEC for freshwater sediment:
- 100 mg/kg sediment dw
Additional information
Based on key studies Call et al., 2001 and Tagatz et al., 1986.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
