100 mg/L

Additional information

A study on algal toxicity was conducted in a modified toxicity study according to EU test guidance 92/69/EEC part C3 and OECD test guideline 201 in compliance with GLP.

This modified algal test has clearly demonstrated that the observed growth inhibition effect of the-test item on Scenedesmus subspicatus was caused only by the indirect effect, the light absorption in the coloured test solutions. Thus, a real toxic effect of the test item on the growth of Scenedesmus subspicatus can be excluded up to the highest test concentration of 100 mg/l.

EC50 > 100mg/L. The substance is not considered to be harmful to algae.
