Additional information

Conclusion on classification

Biodegradation:

Not readily biodegradable (49%) within 28 d (OECD 301 B)

Bioaccumulation:

log Pow: 1.1 (Calculation method based on measured water solubility of phosphorus based anaylsis and measured octanol solubility of neat active test item)

Acute toxicity:

to fish: LL50 (96 h) > 100 mg a.i./L (nominal) for Danio rerio (OECD 203)

to aquatic invertebrates: EL50 (48 h) 72.7 mg a.i./L (nominal) for Daphnia magna (OECD 202)

to aquatic algae: EL50 (72 h) > 100 mg a.i./L (nominal) for Desmodesmus subspicatus based on growth rate (OECD 201)

Chronic toxicity:

to algae: EL10 (72 h) = 85.86 mg a.i./L (nominal) for Desmodesmus subspicatus based on growth rate (OECD 201)

 

Classification justification according to CLP:

Based on the data above the substance (CAS 52585-16-7) is not rapidly biodegradable. Acute aquatic toxicity data are available for three trophic levels. The lowest acute effect value was determined for Daphnia and amounts 72.7 mg a.i./L (EL50, 48 h). Chronic toxicity data are available only for algae with an EL10 of 85.86 mg a.i./L. Based on the available data the test item is classified and labelled as Category Chronic 3 for environmental hazards according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
