acute as well as chronic studies of sufficient reliability are available
for all three trophic levels, as well as reliable microbial toxicity
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.
