Conclusion on classification

Classification and labelling according to acute aquatic toxicity data

Justification for classification or non classification

Three acute tests have been performed with fish, daphnia and algae. The effect with the lowest concentration have been observed in a fish study (LC50 (96 h): 0.028 mg/L). Therefore, a classification related to risk phrase R50 applies, equivalent to H400 (CLP).

Classification and labelling according to chronic aquatic toxicity data, degradation and bioconcentration

Justification for classification or non classification

6PPD is not readily biodegradable and has a log Pow>3. Therefore, a classification related to risk phrase R53 applies. Taking chronic values and the degradability into account, a classification of H410 according to CLP is applicable.
