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.
