Description of key information

In a study with Scenedesmus subspicatus (Blom et al, 1994) no toxicity was observed after 3d exposure to a loading rate of 1640mg/L. The test was carried out according to OECD Guideline 201 and the result was corroborated by the mecocosm study (Heimbach, 1993) where no effects were seen in the phytoplankton up to 1000 and 10,000 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
1 640 mg/L
