Additional information
Aquatic PNECs
Fish, Daphnia and algal acute toxicity endpoints are available. The lowest reported appropriate endpoint was a 72 hour algal ErC50 of 100 mg/L. The following PNECs were calcuated using this endpoint:
PNEC Aqua (freshwater) - Based on an assessment factor of 1000 the PNEC is 0.100 mg/L.
PNEC Aqua (marine water) - Based on an assessment factor of 10000 the PNEC is 0.010 mg/L.
PNEC Aqua (intermittent releases) - Based on an assessment factor of 100 the PNEC is 1.0 mg/L.
STP PNEC
The 3 hour EC50 obtained from an activated sludge respiration study was 650 mg/L. Based on an assessment factor of 100 the PNEC is 6.5 mg/L.
Conclusion on classification
No classification is triggered based on available data, according to EEC Council Directive 79/831/EEC Annex VI, Part II (D) as described in Commission Directive 93/21/EEC or Regulation (EC) No 1272/2008.
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.
