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).
