Additional information

PNEC sediment (freshwater):

K_(susp-water) = 111 m³/m³

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC aqua (freshwater) = 1.33 µg/L

PNEC sediment (freshwater) = (K_susp-water) / RHO_(susp)) * PNEC_water * 1000

= (111/1150) * 1.33 * 1000

= 128.37 µg/kg wwt

= 590.52 µg/kg dwt

The PNEC sediment (freshwater) of dry weight (dw) of MIKP is 590.52 µg/kg corresponding to the wet weight (ww) value of 128.37 µg/kg (conversion factor: 4.6).

PNEC sediment (marine water):

K_(susp-water) = 111 m³/m³

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC aqua (marine water) = 0.133 µg/L

PNEC sediment (marine water) = (K_susp-water) / RHO_(susp)) * PNEC_water * 1000

= (111/1150) * 0.133 * 1000

= 12.84 µg/kg wwt

= 59.05 µg/kg dwt

The PNEC sediment (freshwater) of dry weight (dw) of MIKP is 59.05 µg/kg corresponding to the wet weight (ww) value of 12.84 µg/kg (conversion factor: 4.6).

PNEC soil:

K_(soil-water) = 133 m³/m³

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

PNEC aqua (freshwater) = 1.33 µg/L

= (K_(soil-water) / RHO_(soil)) * PNEC_water * 1000

= (133/1700) * 1.33 * 1000

= 104.05 µg/kg wwt

= 117.58 µg/kg dwt

The PNEC soil of dry weight (dw) of MIKP is 117.58 µg/kg corresponding to the wet weight (ww) value of 104.05 µg/kg (conversion factor: 1.13).

Conclusion on classification

Short term (acute) aquatic toxicity 

Algae is the most sensitive species to the acute toxic effects of the test item with an acute ErC50 of 1.33 mg/L. Based on the these data, the substance has not to be classified with regard to short-term environmental toxicity according to Regulation (EC) No 1272/2008 (CLP/GHS). 

Long term (chronic) aquatic toxicity: 

Algae is the most sensitive aquatic species with an ErC10 of 0.94 mg/L and a NOEC of 0.15 mg/L. The ErC50 in aglae is 1.33 mg/L. The short-term LC50 in Zebrafish (Brachydanio rerio) and the EC50 in Daphnia magna are 1.89 and 4.48 mg/L, respectively. The test substance is readily biodegradable and has a log Pow of 4.2. As a result the substance has to be classified with cat. 2, H411 ( Toxic to aquatic life with long lasting effects) according to Regulation (EC) No 1272/2008 (CLP/GHS).
