Description of key information

Testing is waived on the basis that MMB is not actutely toxic to fish, is biodegradable and is not likely to bioaccumulate.

Key value for chemical safety assessment

Additional information

Testing for long-term toxicity to fish is not considered necessary because the short-term toxicity of MMB to fish is low and the weight of evidence presented here indicates testing is not necessary. Furthermore the substance is readily biodegradable. The low log Kow = 0.18 and the predicted BCF (aquatic species) = 3.16 L/kg ww indicate bioaccumulation is unlikely.
