Additional information

Freshwater algae

In a 96 hour acute toxicity study conducted similar to the OECD guideline 201, the cultures of Scenedesmus subspicatus (new name: Desmodesmus subspicatus) were exposed to Styrene oxide under static conditions.  The 96h EbC10and EbC50values based on cell density were 12 and 32 mg a. i. /L, respectively. There were no compound related phytotoxic effects.
