Additional information

Conclusion on classification

Data for the target substance were extroplated from the source experimental data and are the following:

Fish: 96H-LC50 was determined to be above 127 mg/L.

Invertebrate: The 96H-LC50 was determined to be 177.7mg/L

Algae: The 72H-EC50 were defined at 190.5 and 115.6 mg/L, respectively based on growth rate and biomass.

The substance is readily biodegradable and has a LogKow of -2.79.

On the basis on the above data, the target substance is not classified for the environment, neither for the acute aquatic toxicity nor the chronic aquatic toxicity.
