Additional information

PNEC freshwater sediment:

K_(susp-water) = 13.1

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

 

PNEC_freshwater sediment

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

= (13.1/1150)* 5 E-3 * 1000

= 0.057mg/kg wwt

= 0.262 mg/kg dwt

 

 

PNEC marine water sediment:

K_(susp-water) = 13.1

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marine water sediment

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

= (13.1/1150)*5 E-4* 1000

= 5.7E-03 mg/kg wwt

= 0.0262 mg/kg dwt

 


PNEC soil:

K_(soil-water) = 15

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

 

PNEC_soil

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

= (15/1700)* 5 E-3 * 1000

= 0.044 mg/kg wwt

= 0.0499 mg/kg dwt

Conclusion on classification

Acute toxicity:

The substance does not show any adverse effects in acute aquatic toxicity tests up to its water solubility (< 1 mg/L). Therefore, the substance has not to be classified as acute environmental toxic according to Regulation (EC) No 1272/2008 (CLP/GHS).

Chronic toxicity:

The substance does not show any adverse effects in acute aquatic toxicity tests up to its water solubility. In a study the water solubility of the substance was determined to be < 1 mg/L. As the substance is not ready biodegradable and has a log Kow value of 7.2 indicating a bioaccumulation potential, the substance is classified as chronic aquatic cat. 4 (H413: May cause long lasting harmful effects to aquatic life.) according to Regulation (EC) No 1272/2008 (CLP/GHS).
