Description of key information

The ErC50 for EMA in algae was >110 mg/L
The NOEC for growth of algae was 110 mg/L

Key value for chemical safety assessment

EC50 for freshwater algae:
110 mg/L
EC10 or NOEC for freshwater algae:
110 mg/L

Additional information

In a reliable guideline study according to OECD 201 with an exposure period of 72 hours an EC50 of >100 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 ethyl methacrylate is of low toxicity.
