Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Three key studies were identified that provided results of acute toxicity tests with invertebrates to ethylbenzene, including freshwater invertebrates (Daphnia magna and Ceriodaphnia dubia) and one used the mysid shrimp.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 1.8 mg/L
Marine water invertebrates
Marine water invertebrates
- Effect concentration:
- 2.6 mg/L
Additional information
Numerous acute toxicity tests were available with the freshwater cladoceran, Daphnia magna and one chronic study with Ceriodaphnia dubia. Toxicity results for a variety of saltwater invertebrates were also available. Three key studies were identified with endpoints for Daphnia magna, Mysidopsis bahia (now known as Americamysis bahia) and Ceriodaphnia dubia. A key study identified with exposure of ethylbenzene to D. magna reported a 48-hr EC50 value that ranged from 1.8 to 2.4 mg/L. A second key study was chosen that used Ceriodaphnia dubia in a 7-day reproduction study and at 48 hr, the LC50 value was 3.2 mg/L. Only one key study was identified with a marine invertebrate, the mysid shrimp and the 96-hr LC50 value was 2.6 mg/L. The more conservative endpoint at 48 hours was selected from the D. magna study; therefore 1.8 mg/L was used as the key endpoint for freshwater invertebrates. Along with the three key studies, 6 supporting studies were available with a diverse assemblage of invertebrate species, with a further 10 studies considered unreliable or not assignable (Klimisch 3 or 4).
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.
