Additional information

Conclusion on classification

Classification and labelling according to aquatic toxicity data

Justification for classification or non classification

Three acute tests have been performed with fish, daphnia and algae. The lowest effects concentration has been observed in daphnia (EC50=2 mg/L). Therefore, a the substance is classified according to risk phrases R51.

 

Classification and labelling according to degradation and bioconcentration

Justification for classification or non classification

MDI MT is not readily biodegradable and has a logPow of 7.74 (calculated). Therefore, a classification related to risk phrase R53 is required.

Summary for classification and labelling

EU: R51/53 - toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment

GHS: H411 - Toxic to aquatic life with long lasting effects.
