Additional information

The PNEC derivation was as follows justified:

PNEC freshwater sediment:

K_(susp-water) = 13.6

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_freshwater sediment

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

= (13.6/1150)* 0.313E-03 *1000

= 0.0037 mg/kg wwt

= 0.017 mg/kg dw

 

PNEC marine water sediment:

K_(susp-water) = 13.6

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marine water sediment

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

= (13.6/1150)*0.313E-04* 1000

= 0.00037 mg/kg wwt

= 0.0017 mg/kg dw

 

PNEC soil:

K_(soil-water) = 13.7

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

PNEC_soil

= (K_(soil-water)/ RHO_(soil))*PNEC_freshwater* 1000

= (13.7/1700)*0.313E-03* 1000

= 0.0025 mg/kg wwt

= 0.0028 mg/kg dw

Conclusion on classification

Conclusion on classification

Environmental classification justification

The environmental classification was justified according to the criteria for classification for hazards to the aquatic environment according to regulation (EC) No 1272/2008.

 

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 biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the short-term toxicity to aquatic invertebrates. This study revealed a 48h-EC50 of 0.313 mg/L. The 72h-EC10 of a toxicity to alga and cyanobacteria test was determined to be 0.435 mg/L and the 72h-EC50 was determined to be 0.805 mg/L. Based on these results, the substance is classified as Aquatic acute category 1 and as Aquatic chronic category 3 according to table 4.1.0 of Annex I of Regulation (EC) No. 1272/2008 and as H400: Very toxic to aquatic life and as H412: Harmful to aquatic life with long-lasting effects, according to Regulation (EC) No 1272/2008 (CLP) as amended for the sixth time in Directive EC 605/2014.
