Short-term toxicity to aquatic invertebrates

Description of key information
There are no valid test data on acute toxicity to daphnia available.
An existing OECD 202 study with dodecyl methacrylate was considered as
invalid, because it was performed with the solvent
acetone and test concentrations were several orders of magnitude higher
than the water solubility.
As a consequence of the very low water solubility of the long-chain
methacrylate esters (C12 – C22) which is < 1 µg/l, a long-term toxicity
test with daphnia was performed instead of an acute test (see below).
