Description of key information

The ErC50 for MMA in algae was >  100 mg/L.
The NOEC for growth of algae was 110 mg/L.

Key value for chemical safety assessment

Additional information

In a reliable guideline study according to OECD guideline 201 with an exposure period of 72 hours an EC50 of >110 mg/L was established based on the inhibition of the growth rate. In the same study an NOEC of 110 mg/L was determined. Based on these results methyl methacrylate is of low toxicity to algae.
