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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
