Additional information
PNEC (freshwater sediment):
K(susp-water) = 0.905 m³/m³
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment = (Ksusp-water) / RHOsusp) * PNEC (freshwater) * 1000
= (0.905/1150) * 0.1 * 1000
= 0.0787 mg/kg wwt
= 0.362 mg/kg dwt
The PNEC (freshwater sediment) of dry weight (dw) is 0.362 mg/kg corresponding to the wet weight (ww) value of 0.0787 mg/kg (conversion factor: 4.6).
PNEC (marine sediment):
K(susp-water) = 0.905 m³/m³
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment = (Ksusp-water) / RHOsusp) * PNEC (marine water) * 1000
= (0.905/1150) * 0.01 * 1000
= 0.0079 mg/kg wwt
= 0.0362 mg/kg dwt
The PNEC (marine water - sediment) of dry weight (dw) is 0.0362 mg/kg corresponding to the wet weight (ww) value of 0.0079 mg/kg (conversion factor: 4.6).
PNEC soil:
K(soil-water) = 0.206 m³/m³
RHO(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil
= (K(soil-water) / RHOsoil) * PNEC (freshwater) * 1000
= (0.206/1700) * 0.1 * 1000
= 0.0121 mg/kg wwt
= 0.0137 mg/kg dwt
The PNEC (soil) of dry weight (dw) is 0.0137 mg/kg corresponding to the wet weight (ww) value of 0.0121 mg/kg (conversion factor: 1.13).
Conclusion on classification
Aquatic acute toxicity
48 h, EC50 (Daphnia magna): >100 mg/L (nominal)
72 h, ErC50 (Raphidocelis subcapitata) >100 mg/L (nominal)
96 h, LC50 (Danio rerio): >100.0 mg/L (nominal)
Aquatic chronic toxicity
72 h, ErC10 (Raphidocelis subcapitata): 26.79 mg/L (nominal)
Biodegradation: Inherently biodegradable: 48.6 % after 28 days (OECD 301D)
Classification according to CLP
Based on the data above, the substance has not to be classified for short-term (acute) or long-term (chronic) toxicity according to the 17th ATP of the Regulation (EC) No 1272/2008 (CLP).
