Conclusion on classification

Acute toxicity:

Fish are the most sensitive species to the toxic effects of allyl methacrylate with an acute EC50 of 0.61 mg/L. Based on the results obtained in the aquatic toxicity studies, allyl methacrylate has to be classified Aquatic acute toxic cat.1 (H400: Very toxic to aquatic life.) according to Regulation (EC) No 1272/2008 (CLP).

Chronic toxicity:

One long-term study in freshwater invertebrates is available for allyl methacrylate. The 21-d EC10 based on reproduction is 0.272 mg/L (95 % c.l. 0.130 – 0.402 mg/L). As allyl methacrylate is readily biodegradable the substance is classified as aquatic chronic cat. 3 (H412: harmful to aquatic life with long lasting effects) according to Regulation (EC) No 1272/2008 (CLP).
