Description of key information

A study according to OECD Guideline 201 was performed to assess the toxicity of the test item to freshwater algae. 

Algae were exposed to an aqueous solution of the test item at nominal concentrations of 0.010, 0.032, 0.10, 0.32, 1.0, 3.2, 10, and 32 100% v/v saturated solution for 72 hours. Geometric mean measured concentrations were determined.

The 72h-ErC50 is 0.73 mg/L (geomean measured test concentration).

Key value for chemical safety assessment

EC50 for freshwater algae:
0.73 mg/L
