Additional information

All assessment and conversion factors used in the above PNEC calculations were taken from the ECHA guidance document "Guidance on information requirements and chemical safety assessment; Chapter R.10: Characterisation of dose [concentration]-response for environment" along with appropriate equations and methodologies. Correction factors were taken from the ECHA guidance document "Guidance on information requirements and chemical safety assessment; Chapter R.8: Characterisation of dose [concentration]-response for human health" along with appropriate equations and methodologies.

Conclusion on classification

According to the key information available, the substance is not readily biodegradable, has a BCF between 1-10 and has a 96 hour (fish) LC50 value of 1.13 mg/l.

The substance is currently classified as R51/53: Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment according to Annex 1 of Directive 67/548/EEC and Aquatic Chronic Category 3 according to EC Regulation 1272/2008.

Based upon the available information the substance is classified by the registrant as R51/53: Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment according to Directive 67/548/EEC and Aquatic Chronic Category 2 according to EC Regulation 1272/2008.
