Additional information

PNEC freshwater sediment:

K_(susp-water) = 112

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

 

PNEC_freshwater sediment

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

= (112/1150)* 9.8E-04 *1000

= 0.095 mg/kg wwt

= 0.437 mg/kg dwt

PNEC marine water sediment:

K_(susp-water) = 112

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marine water sediment

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

= (112/1150)*9.8E-05* 1000

= 0.0095 mg/kg wwt

= 0.0437 mg/kg dwt

PNEC soil:

K_(soil-water) = 133

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

 

PNEC_soil

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

= (133/1700)* 9.8E-04* 1000

= 0.0766 mg/kg wwt

= 0.087 mg/kg dwt

Conclusion on classification

Acute toxicity:

Fish are the most sensitive species to the acute toxic effects of the test item with an acute EC50 of 0.33 mg/L. Based on the these data, the substance has to be classified with regard to acute environmental toxicity with aquatic acute cat. 1 (H400: Very toxic to aquatic life, M = 1) according to Regulation (EC) No 1272/2008 (CLP/GHS).

Chronic toxicity:

Classification of the test item is based on long-term toxicity data.

Aquatic invertebrates are the most sensitive species to toxic long term effects of the test item with a chronic NOEC of 0.049 mg/L. Algae toxicity (72 h) confirms this value with an EC10 value of 0.06 mg/L. As the test item is not ready biodegradable, the substance is classified as chronic aquatic cat. 1 (H410: Very toxic to aquatic life with long lasting effects, M = 1) according to Regulation (EC) No 1272/2008 (CLP/GHS).
