Additional information

The PNEC derivation was as follows justified:

 

PNEC freshwater sediment: 0.4124 mg/kg dw

K_(susp-water) = 1.031

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_freshwater sediment

= (K_(susp-water)/ RHO_(susp)) * PNEC_freshwater * 1000

= (1.031/1150) * 0.1 * 1000

= 0.08965 mg/kg wwt

= 0.4124 mg/kg dw

 

PNEC marine water sediment: 0.04124 mg/kg dw

K_(susp-water) = 1.031

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marinewater sediment

= (K_(susp-water)/ RHO_(susp)) * PNEC_marinewater * 1000

= (1.031/1150) * 0.01 * 1000

= 0.008965 mg/kg wwt

= 0.04124 mg/kg dw

 

PNECsoil: 0.02373 mg/kg dw

K_(soil-water) = 0.357

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

PNEC_soil

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

= (0.357/1700) * 0.1 * 1000

= 0.021 mg/kg wwt

= 0.02373 mg/kg dw

Conclusion on classification

Classification related key information

- Biodegradation: not readily biodegradable: 18.9% degradation (O2 consumption) after 28 days (OECD TG 301D)

- Bioaccumulation: log Pow = -0.58 at 25 °C (calculated)

 

Aquatic acute toxicity

- Aquatic invertebrates: EC50 (48 h) > 100 mg/L; EC10 > 100 mg/L (nominal, Daphnia magna, OECD 202)

- Algae: ErC50 (72 h) > 100 mg/L; ErC10 = 21.8 mg/L (nominal, Raphidocelis subcapitata, OECD 201)

- Fish: LC50 (96 h) > 100 mg/L (nominal, Danio rerio, OECD 203)

 

Aquatic chronic toxicity

- Algae: ErC10 (72 h) = 21.8 mg/L (nominal, Raphidocelis subcapitata, OECD 201)

 

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was not found to be readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae (Raphidocelis subcapitata). The test revealed a 72-hour ErC50 and ErC10 (growth rate) of >100 mg/L and 21.8 mg/L, respectively. The log Pow was calculated to be -0.58. Based on these results, the substance is neither classified for aquatic short-term (acute) toxicity nor for aquatic long-term (chronic) toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the fourteenth time in Regulation (EU) 2020/217.
