Additional information

PNEC freshwater sediment:

Koc = 182 (calculated)

K_(susp-water) = 5.46

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

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

= (5.46/1150)* 0.00818 *1000

= 0.03884 mg/kg wwt

= 0.179 mg/kg dwt

----------------------------

PNEC marine water sediment:

Koc=182 (calculated)

K_(susp-water) = 5.46

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

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

= (5.46/1150)*0.000818* 1000

= 0.003884 mg/kg wwt

= 0.0179 mg/kg dwt

-----------------------------

PNEC soil:

Koc=182 (calculated)

K_(soil-water) = 5.67

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

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

= (5.67/1700)* 0.00818* 1000

= 0.0273 mg/kg wwt

= 0.031 mg/kg dwt

Conclusion on classification

Aquatic acute toxicity

48 h, EC50 (Daphnia magna): > 45.5 mg/L (measured)

72 h, ErC50 (Pseudokirchnerialla subcapitata): 44.8 mg/L (measured)

96 h, LC50 (Danio rerio): 8.18 mg/L (measured)

 

Aquatic chronic toxicity

72 h, EC10 (Pseudokirchnerialla subcapitata): 29.8 mg/L based on growth (measured)

Biodegradation: Readily biodegradable: 79 % (O2 consumption) after 28 d (EU Method C.4-E)

log Kow = 2.36 (measured), log Koc = 2.26 (calculated)

 

Classification according to CLP

Based on the data above, the substance has not to be classified for acute or chronic toxicity according to the 10th ATP of the Regulation (EC) No 1272/2008 (CLP).
