Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

1. European Union Risk Assessment Report of Acrolein (EU, 2001)

Fresh water

For Daphnia magna a three generation 64-days NOEC-value of 16.9 μg/l is reported. It has to be noted that the long exposure time of 64 days is not according to the recommended exposure time of the OECD guidelines (14 or 28 days).

In addition a long-term NOEC value is available for the mollusc Dreissena polymorpha. However the NOEC (mortality) of 1800 μg/l is derived in a 14 days experiment, which may be considered relatively short for a long-term test with this species (average life time of D. polymorpha is about two years).

Marine invertebrates

Long-term toxicity data for marine invertebrates are not available.

2. Agreement with further international Reports and Studies published after finalisation of the EU Risk Assessment Report 2001  

WHO (2002): In a 64-day exposure of the zooplankton Daphnia magna, 100% mortality occurred in the F2 generation at 42.7 μg/litre. The NOEC for survival was estimated to be 16.9 μg/litre. In another study, a subchronic 14-day NOEC of 1800 μg/litre was derived for the mollusc Dreissena polymorpha.

6. Conclusions

The lowest reported effect concentration in a three generation study is a 64-days NOEC-value of 16.9 μg/l for Daphnia magna.
