Additional information
The PNEC derivation was as follows justified:
PNEC freshwater sediment:
K_(susp-water) = 9.64
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_water * 1000
= (9.64/1150)*0.005*1000
= 0.042 mg/kg wwt
= 0.193 mg/kg dw
PNEC marine water sediment:
K_(susp-water) = 9.64
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine water sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_marine water* 1000
= (9.64/1150)* 0.0005 * 1000
= 0.004 mg/kg wwt
= 0.019 mg/kg dw
PNEC soil:
K_(soil-water) = 10.7
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil
= (K_(soil-water)/ RHO_(soil))*PNEC_freshwater*1000
= (10.7/1700)*0.005*1000
= 0.031 mg/kg wwt
= 0.035 mg/kg dw
Conclusion on classification
Aquatic acute toxicity
96 h, LC50 (Danio rerio): 11.1 mg/L (nominal concentration)
48 h, EC50 (Daphnia magna): 16.5 mg/L (geometric mean concentration)
72 h, ErC50 (Pseudokirchneriella subcapita): 4.68 mg/L (nominal concentration)
Aquatic chronic toxicity
72 h, ErC10 (Pseudokirchneriella subcapita): 2.75 mg/L (nominal concentration)
Biodegradation: Inherently biodegradable: 38 % (% degradation O2 consumption) after 28 days (OECD 301 D)
Partition coefficient: log Kow = 2.81 for isomer 1 and 2.98 for isomer 2 at 23.6 °
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. The test substance was found to be not readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the toxicity test to algae. This study revealed a 72h-EC50 of 4.68 mg/L and the 72h-EC10 of a toxicity to alga and cyanobacteria test with the test substance was determined to be 2.75 mg/L. Based on these results, the substance is not classified as aquatic acute toxicity and based on these results the substance is classified as aquatic chronic category 3 according to table 4.1.0 of Annex I of Regulation (EC) No 1272/2008 and as H412: Harmful to aquatic life with long lasting effects, according to Regulation (EC) No 1272/2008 (CLP) as amended for the eighth time in Commision Regulation (EU) 2016/1688.
