Data availability
For EMA acute as well as chronic studies of sufficient reliability are available for all three trophic levels, as well as reliable microbial toxicity data.
Summary
The aquatic toxicity of ethyl methacrylate was investigated on all three trophic levels using acute as well as long-term toxicity tests. The results showed that the test substance is of low toxicity to fish (LC50 100 mg/L) and algae and harmful to aquatic invertebrates (EC50 > 66 mg/L). In the long-term toxicity tests, invertebrate toxicity in a long-term Daphnia magna test was the most sensitive endpoint (NOEC 18 mg/L). The microbial EC50 was determined to be 1000 -1800 mg/L based on data from an activated sludge protocol.
