Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to aquatic invertebrates
Administrative data
Link to relevant study record(s)
Description of key information
No data providing insights to the likely acute toxicity to aquatic freshwater invertebrates was identified on DIDS (or DIDA or DOS).
A secondary source describes an unpublished study (performed according to OECD Guideline 202, but not to GLP) in which D. magna were exposed to DEHS at a nominal limit concentration of 1000 mg/L of freshwater for up to 48 hr. No immobility was seen over the treatment period. A NOEC of 1000 mg/L (nominal) can be assumed (Anon, 1994b).
No acute toxicity data on marine water invertebrates are available for DIDS (or DIDA, DEHS or DOS).

Additional information
No data providing insights to the likely acute toxicity to freshwater or marine aquatic invertebrates were identified on DIDS.
Relevant read-across data:
A secondary source describes an unpublished acute toxicity study on freshwater Daphnia magna treated with DEHS, performed in accordance with OECD Guideline 202, but not to GLP. D. magna (10 per replicate, with 4 replicates for the test substance and 2 for the untreated control) were exposed to DEHS at a nominal concentration of 1000 mg/L for 48 hr. It was noted that analytical test concentrations of DEHS were very low [specific concentrations were not given], probably due to low water solubility. Mobility was assessed at 24 and 48 hr. Immobility was not seen at either 24 or 48 hr; a NOEC of 1000 mg/L (nominal) can be assumed. According to the citing source, "data would suggest that [the] test substance [is] not expected to cause any immobilization at its water saturation limit" (Anon, 1994b).
No acute toxicity data on marine water invertebrates are available on relevant read-across materials.
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.
