Additional information
PNEC sediment(freshwater), PNEC sediment (marine waters), PNEC soil
No toxicity tests with sediment dwelling or terrestrial organisms are available. Thus, in accordance with the Guidance on information requirements and chemical safety assessment, Chapter R.10: Characterisation of dose [concentration]-response for environment, 2008, the PNEC for freshwater and marine water sediment as well as the PNEC soil have been calculated with the equilibrium partitioning method using EUSES 2.1.
The following data have been taken into account for calculation:
Molecular weight |
284 (weighted mean) |
Melting point |
3.3°C |
Vapour pressure |
0.0015 Pa at 20°C |
Water solubility |
211 mg/L at 20°C |
Log Kow |
2.05 at 25°C |
PNEC Aqua(freshwater) |
13 µg/L |
PNEC Aqua(marine water) |
1.3 µg/L |
The calculation resulted in a PNEC sediment(freshwater) of 205 µg/kg sediment dw, a PNEC sediment (marine waters) of 20.5 µg/kg sediment dw and a PNEC soil of 33.4 µg/kg soil dw.
Conclusion on classification
Based on the results from the aquatic toxicity (LC50/EC50 values between 10 and 100 mg/l) and since the substance is readily biodegradable and has a log Pow below 4, the substance is not classified for environmental hazards according to Directive 67/548/EEC and CLP Regulation 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).
