Conclusion on classification

Three acute endpoints for three different trophic levels are available. The lowest ErC50 is found for algae and is 24 mg/L. One chronic endpoint for algae, the most sensitive species is available, The ErC10 is 4.7 mg/L.

The substance has a log Kow of 2.4 and is not readily biodegradability.

 

Acute classification:

The lowest acute endpoint for algae is greater than 1 mg/L, the substance does not need to be classified.

 

Chronic classification:

The substance is not readily biodegradable and the chronic ErC10 for algae is greater than 1 mg/L. This would not lead to chronic classification.

Because only one chronic endpoint is available, chronic classification is also based on acute data: with an ErC50 of 24 mg/L and the substance being not readily biodegradable the substance would be classified Category chronic 3.

 

Proposal for classification:

Acute: Not classified

Category chronic 3.
