Additional information
The PNEC derivation was as follows justified:
PNEC freshwater sediment:
K_(susp-water) = 0.979
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment
= (K_(susp-water)/RHO_(susp))*PNEC_water * 1000
= (0.979/1150)*0.1*1000
= 0.085 mg/kg wwt
= 0.39 mg/kg dw
PNEC marine water sediment:
K_(susp-water) = 0.979
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine water sediment
= (K_(susp-water)/RHO_(susp))*PNEC_marine water* 1000
= (0.979/1150)* 0.01 * 1000
= 0.009 mg/kg wwt
= 0.039 mg/kg dw
PNEC soil:
K_(soil-water) = 0.295
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil
= (K_(soil-water)/ RHO_(soil))*PNEC_freshwater*1000
= (0.295/1700)*0.1*1000
= 0.017 mg/kg wwt
= 0.019 mg/kg dw
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. The test substance was found to be not readily biodegradable under the test conditions. The most sensitive tests for the aquatic compartment was the toxicity test to fish. The test revealed a 96h-LC50 of > 100 mg/L. In addition the 72h-EC10 of a toxicity to alga and cyanobacteria test with the surrogate test substance was determined to be 18 mg/L. Based on these results, the substance is neither classified as aquatic acute toxicity nor classified as aquatic chronic according to table 4.1.0 of Annex I of Regulation (EC) No 1272/2008 and according to Regulation (EC) No 1272/2008 (CLP) as amended for the twelfth time in Regulation (EU) 2019/521.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
