With high probability acutely not harmful to aquatic algae and cyanobacteria. No toxic effects occur at the range of solubility.
In a 72h non-GLP guideline study using Scenedesmus
subspicatus, an EC50 of > 100 mg/L for biomass was determined
according to OECD 201.
After 72 hours, algal cell counts for the
1.0 , 10, and 100 mg/L test levels were 104, 94, and 94% of the pooled
control population, respectively. The NOEC based on cell number was >
100 mg/L. DMF was used as a solvent with a concentration of 0.01% in
The effect concentration is well above the
solubility limit of the test substances (water solubility < 0.005 mg/L
at 20°C, see chapter 4.8 in IUCLID). Therefore, it represents a worst
case assumption where water solubility is achieved by use of solvent. In
conclusion, the substance shows no effect in the range of water
