Additional information
The PNEC derivation was as follows justified:
PNEC freshwater sediment:
K_(susp-water) = 3.43
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_water * 1000
= (3.43/1150)*0.016*1000
= 0.0477 mg/kg wwt
= 0.22 mg/kg dw
PNEC marine water sediment:
K_(susp-water) = 3.43
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine water sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_marine water* 1000
= (3.43/1150)* 0.0016 * 1000
= 0.00477 mg/kg wwt
= 0.022 mg/kg dw
PNEC soil:
K_(soil-water) = 3.24
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil
= (K_(soil-water)/ RHO_(soil))*PNEC_freshwater*1000
= (3.24/1700)*0.016*1000
= 0.0305 mg/kg wwt
= 0.034 mg/kg dw
Conclusion on classification
Aquatic acute toxicity
96h, LC50 (Danio rerio): 16.1 mg/L (nominal)
48 h, EC50 (Daphnia magna): 117 mg/L (nominal)
72 h, EC10 (Algae): 47.4 mg/L (measured), EC50: 61.9 mg/L
Biodegradation: Readily biodegradable: 75 % (O2 consumption) after 28 days (OECD 301 D)
log Kow = 1.91 at 21.9 °C
log Koc = 2.00 at 25°C
Classification according to CLP
Based on the data above, the substance has not to be classified for acute or chronic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EU) No 2017/776.
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.
