Additional information

REACH endpoints for this substance are filled using experimental data for the substance itself.

This data is also used for classification purposes.

Conclusion on classification

Environmental classification is assessed based on the lowest acute and chronic values from substance specific ecotoxicity test data.

The lowest acute value is an EC50 of 15.9 µg palladium di(4-oxopent-2-en-2-oate)

/L for fish (mortality). The lowest chronic value is an EC10 of 9.3 µg

palladium di(4-oxopent-2-en-2-oate) for D. magna (reproduction).

These threshold values are used for classification purposes. The corresponding environmental classification is:

Acute Category 1 (M-factor 10)

Chronic Category 1 (M-factor 10).
