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
