Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
