Additional information

Predicted No Environmental Effect Concentrations (PNECs) have been calculated using the results of environmental toxicity tests and applying default assessments factors.

Conclusion on classification

Classification for environmental effects is justified based on the observed toxicity in acute tests in three aquatic aquatic compartments. While the substance is not readily biodegradable with non-adapted inocula, it is readily biodegradable with an adapted inoculum.
