Description of key information
No mortality and no effect of methylal at concentrations up to 1 g/L was observed among Brachydanio rerio (new name: Danio rerio) during 96-hour exposure in a study with a reliability code of 1. Thus, NOEC is 1 g/L and LC50 for freshwater is higher to 1 g/L.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 1 g/L
Additional information
LC50 value for freshwater fish is supported by two supporting studies. In the first one, LC50 and EC50 were determined to be 6.99 and 6.36 g/L, respectively, in Pimephales promelas. In the second one, methylal at 5.0 ppm induced no mortality to Salmo trutta (trout), Lepomis macrochirus (Bluegill sunfish), Perca flavescens (Yellow perch), Carassius auratus (Goldfish) during 24 hours.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
