Additional information
PNEC freshwater sediment:
K_(susp-water) = 36.9
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_water * 1000
= (36.9/1150)* 0.00156 *1000
= 0.05 mg/kg wwt
= 0.23 mg/kg dwt
PNEC marine water sediment:
K_(susp-water) = 36.9
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine water sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_marine water* 1000
= (36.9/1150)*0.000156* 1000
= 0.005 mg/kg wwt
= 0.023 mg/kg dwt
PNEC soil:
K_(soil-water) = 43.4
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil
= (K_(soil-water)/ RHO_(soil))*PNEC_water * 1000
= (43.4/1700)* 0.00156* 1000
= 0.04 mg/kg wwt
= 0.045 mg/kg dwt
Conclusion on classification
Acute aquatic toxicity:
Algae is the most sensitive aquatic species with an EC50 of 1.56 mg/L. According to Regulation (EC) No 1272/2008 (CLP, GHS) the test item does not have to be classified regarding short-term (acute) toxicity to the environment as the lowest LC50 value is above 1 mg/L.
Chronic aquatic toxicity:
Algae is the most sensitive aquatic species with an EC50 of 1.56 mg/L. For the derivation of classification and labelling also the 72-h EC10 value based on growth rate was determined as 0.49 mg/L has to be taken into acount. Under the test conditions the percentage of ready biodegradation of the test substance reached a mean of -0.8 % (that was considered as zero biodegradation) after 28 days based on its COD. The test item can be considered to be not readily biodegradable. As a result the substance has to be classified as env. long-term (chronic) tox. cat 2 (H411: Toxic to aqautic life with long lasting effects) according to Regulation (EC) No 1272/2008 (CLP/GHS), as amended for the fifteenth time in Regulation (EU) No 2020/1182.
