Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No mortality was observed in an acute toxicity (limit) test when earthworms were exposed to acrylic acid in an artificial soil.
LC50 (14 d) > 1000 mg/kg dw (Eisenia foetida foetida, 88/302/EEC, C.8)
Key value for chemical safety assessment
Additional information
An acute earthworm toxicity study was conducted in Eisenia foetida foetida according to the EU method 88/302/EEC, C.8 and in compliance with GLP regulations (Huels AG, 1995). Groups of ten earthworms per replicate (4 replicates/treatment group) were exposed to 1000 mg acrylic acid/kg dry weight in an artificial soil (limit test). A control was run in parallel. Mortality was recorded after 7 and 14 days. All test animals survived the treatment until test termination. Thus, the LC50 was determined to be greater than 1000 mg/kg dry weight.
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.
