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.
