Additional information

PNEC freshwater sediment:

K_(susp-water) = 19.8

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

 

PNEC_freshwater sediment

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

= (19.8/1150)* 0.000261 *1000

= 0.0049 mg/kg wwt

= 0.021 mg/kg dwt

PNEC marine water sediment:

K_(susp-water) = 19.8

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marine water sediment

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

= (19.8/1150)*0.0000261* 1000

= 0.00049 mg/kg wwt

= 0.0021 mg/kg dwt

PNEC soil:

K_(soil-water) = 22.8

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

 

PNEC_soil

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

= (22.8/1700)* 0.000261* 1000

= 0.0035 mg/kg wwt

= 0.00395 mg/kg dwt

Conclusion on classification

Acute Toxicity

Algae is the most sensitive species with a EC50 value of 0.261 mg/L. The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. As a result the substance is considered to be classified as env. acutetoxic cat. 1, H410, M-Factor 1, to the environment as the lowest EC50 is <= 1mg/L under Regulation (EC) No 1272/2008, as amended for the sixth time in Regulation EC 605/2014. The substance has to be classified as R50 under Directive 67/548/EEC, as amended for the 31st time in Directive 2009/2/EG.

Chronic toxicity

Algae is the most sensitive species in chronic studies with a EC50 value of 0.261 mg/L. As chronic data from fish and Daphnia are not available the classification is based on the chronic data of the algae. The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. As a result the substance has to be classified as env. chronic tox. cat. 3, H412, according to Regulation (EC) No 1272/2008 (CLP/GHS) , as amended for the sixth time in Regulation EC 605/2014. The test on biodegradability showed that the substance is readily biodegradable. The test substance has not to be classified regarding chronic toxicity to the environment according to Directive 67/548/EEC.
