Additional information
The PNEC for sediment is not possible to calculate at this time on the basis of real data, as insufficient data is available to assess these endpoints. As such, assessment utilising EUSES v2.1.1 has been carried out for this endpoint.
Conclusion on classification
The substance is classified on the basis of the results noted in the acute fish and Daphnia studies and is as follows:
Classified under the Dangerous Substances Directive (67/548/EEC) as:
R52/53 Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
According to Regulation (EC) No 1272/2008 the substance is also classified as:
H412: Harmful to aquatic life with long lasting effects.
The environmental studies conducted on the substance have all been ranked reliability 1 according to the Klimish et al system. This ranking was deemed appropriate because the studies were conducted to GLP and in compliance with agreed protocols. Sufficient dose ranges and numbers are detailed; hence it is appropriate for use based on reliability and animal welfare grounds.
The results triggered classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008) as listed above.
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.
