Description of key information

With high probability 1,3,5-trioxane is not acute harmful to aquatic algae and cyanobacteria.

Key value for chemical safety assessment

Additional information

The determination of the inhibitory effect of 1,3,5-trioxane on Scenedesmus subspicatus was performed according to EG-guideline 88/302/EWG (Annex V, C.: Algal inhibition test). The results of this study showed no effect up to the highest test concentration of 500 mg/L after 72 h exposure. Therefore, with high probability 1,3,5-trioxane is not acute harmful to aquatic algae.
