Description of key information

A bioaccumulation study is available with DMH conducted in accordance with OECD Guideline 305E. DMH does not bioconcentrate in fish tissue.

Key value for chemical safety assessment

Additional information

Concentrations of radioactivity in edible and non-edible tissues of bluegill sunfish (Lepomis macrochirus) exposed to 14C-DMH at 1.0 ppm concentrations after a 42 days exposure period were lower than the limit of quantitation, therefore DMH did not bioconcentrate in fish tissue.
