Description of key information

A relevant exposure of sediment organisms is not expected.

Key value for chemical safety assessment

Additional information

No information concerning effects of methyl methacrylate on sediment-organisms are available. However, since the physicochemical data indicate that the substance is not adsorptive (log Koc = 0.94 – 1.86) or bioaccumulative (log Pow = 1.38), a significant distribution into the sediment compartment and a considerable exposure of sediment organisms is not expected. Hence, information about effects on sediment organisms is not required and the equilibrium partitioning method has been used for assessing the hazard to sediment organisms
