Description of key information

From the available acute data for structural analogue substances and the chronic data that are available, for all 3 trophic levels, for the structural  analogue (methyl methacrylate) and the primary metabolite (methacrylic acid) there is no indication that fish are any more sensitive than aquatic invertebrates and algae to this substance. Therefore, performing the chronic fish study, a vertebrate study falling under the animal protection legislation of the EU (86/609/EEC), is unjustified.

Key value for chemical safety assessment
