Additional information

PNEC sediment (freshwater):

Ksusp-water: 3.57 m³/m³
RHOsusp: 1150 kg/m³
Conversion factor (ww -> dw): 4.6

PNEC aqua (freshwater): 0.114 µg/L


PNEC sediment (freshwater) = (Ksusp-water/RHOsusp) * PNEC aqua (freshwater) * 1000
= (3.57/1150) * 0.114 * 1000
= 0.35 µg/kg ww
= 1.63 µg/kg dw

The PNEC sediment (freshwater) of dry weight (dw) of the test substance is 1.63 µg/kg corresponding to the wet weight (ww) value of 0.35 µg/kg (conversion factor: 4.6).

PNEC sediment (marine water):

Ksusp-water: 3.57 m³/m³
RHOsusp: 1150 kg/m³
Conversion factor (ww -> dw): 4.6

PNEC aqua (marine water): 0.0114 µg/L


PNEC sediment (marine water) = (Ksusp-water/RHOsusp) * PNEC aqua (marine water) * 1000
= (3.57/1150) * 0.0114 * 1000
= 0.04 µg/kg ww
= 0.16 µg/kg dw

The PNEC sediment (freshwater) of dry weight (dw) of the test substance is 0.16 µg/kg corresponding to the wet weight (ww) value of 0.04 µg/kg (conversion factor: 4.6).

PNEC soil:

Ksoil-water: 3.41 m³/m³
RHOsoil: 1700 kg/m³
Conversion factor (ww -> dw): 1.13

PNEC aqua (freshwater): 0.114 µg/L


PNEC soil = (Ksoil-water/RHOsoil) * PNEC aqua (freshwater) * 1000
= (3.41/1700) * 0.114 * 1000
= 0.23 µg/kg ww
= 0.26 µg/kg dw


The PNEC soil of dry weight (dw) of the test substance is 0.26 µg/kg corresponding to the wet weight (ww) value of 0.23 µg/kg (conversion factor: 1.13).

Conclusion on classification

Acute toxicity:

Based on the results of the acute toxicity tests to aquatic organisms (most sensitive species Algae with an ErC50 (72h) = 9.5E-03 mg//L, measured) and taking into account the provisions laid down in Regulation (EC) No. 1272/2008 (CLP), Olaflur has to be classified as very toxic to aquatic organisms, cat. 1 (H 400). In addition, a M-factor of 100 is proposed due to 0.001 mg/L < ErC50 < 0.01 mg/L.

Chronic toxicity:

Regarding the chronic toxicity, a long-term toxicity test with Daphnia magna (NOEC (21-d) = 8.3E-02 mg/L, measured) and an algae test (EC10 (72h) = 5.7E-03 mg/L, measured) is available. Algae are the most sensitive species to the toxic effects of Olaflur with an EC10 of 5.7E-03 mg/L. Based on this, the substance is classified as very toxic to aquatic life with long lasting effects, cat. 1 (H410) according to Regulation (EC) No 1272/2008 (CLP). In addition, a M-factor of 1 is proposed due to 0.001 < NOEC ≤ 0.01 mg/L and the substance is readily biodegradable.
