Additional information
PNEC freshwater sediment:
K (susp-water) = 191 m3/m3
RHO (susp) = 1150 kg/m3
Conversion factor (wwt -> dwt): 4.6
PNEC (freshwater sediment) = (K (susp-water)/ RHO (susp))*PNEC (water) * 1000
= (191/1150)* 0.1 mg/L * 1000
= 16.6 mg/kg wwt
= 76.36 mg/kg dwt
PNEC marine water sediment:
K (susp-water) = 191 m3/m3
RHO (susp) = 1150 kg/m3
Conversion factor (wwt -> dwt): 4.6
PNEC (marine water sediment) = (K (susp-water)/ RHO (susp))*PNEC (marine water) * 1000
= (191/1150)* 0.01 mg/L * 1000
= 1.66 mg/kg wwt
= 7.636 mg/kg dwt
PNEC soil:
K (soil-water) = 228 m3/m3
RHO (soil) = 1700 kg/m3
Conversion factor (wwt -> dwt): 1.13
PNEC (soil) = (K (soil-water)/ RHO (soil))*PNEC (water) * 1000
= (228/1700)* 0.1 * 1000
= 13.41 mg/kg wwt
= 15.15 mg/kg dwt
Conclusion on classification
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, as amended for
the twelfth time in Regulation (EU) 2019/521.
Acute aquatic toxicity:
Based on the results obtained, substance HAT-ISO is not classified or labelled for acute aquatic toxicity, according to Regulation (EC) No 1272/2008 (CLP) as all acute LC/EC50 values were well above 100 mg/L.
Chronic toxicity:
Based on the study results (no toxicity up to 100 mg/L, not readily biodegradable, very low water solubility and high Log Pow) the substance is classified as aquatic chronic cat. 4 (H413) according to Regulation (EC) No 1272/2008.
