Additional information
PNEC sediment (freshwater):
K_(susp-water) = 0.979
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC aqua (freshwater) = 0.518 mg/L
PNEC sediment (freshwater) = (K_(susp-water)/RHO_(susp)) * PNEC aqua (freshwater) * 1000
= (0.979/1150) * 0.518 * 1000
= 0.44 mg/kg ww
= 2.03 mg/kg dw
The PNEC sediment (freshwater) of dry weight (dw) of APS is 2.03 mg/kg corresponding to the wet weight (ww) value of 0.44 mg/kg (conversion factor: 4.6).
PNEC sediment (marine water):
K_(susp-water) = 0.979
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC aqua (marine water) = 0.022 mg/L
PNEC sediment (marine water) = (K_(susp-water)/RHO_(susp)) * PNEC aqua (marine water) * 1000
= (0.979/1150) * 0.022 * 1000
= 0.02 mg/kg ww
= 0.09 mg/kg dw
The PNEC sediment (marine water) of dry weight (dw) of APS is 0.09 mg/kg corresponding to the wet weight (ww) value of 0.02 mg/kg (conversion factor: 4.6).
PNEC soil:
K_(soil-water) = 0.295
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC aqua (freshwater) = 0.518 mg/L
PNEC soil = (K_(soil-water)/RHO_(soil)) * PNEC (freshwater) * 1000
= (0.295/1700) * 0.518 * 1000
= 0.09 mg/kg ww
= 0.1 mg/kg dw
The PNEC soil of dry weight (dw) of APS is 0.1 mg/kg corresponding to a wet weight (ww) value of 0.09 mg/kg (conversion factor: 1.13).
Conclusion on classification
Based on the results obtained, substances of the Persulfate Category were not classified and labelled, according to Regulation (EC) No 1272/2008, as amended for the fifteenth time in Regulation (EU) 2020/1182.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
