Additional information

 


PNEC freshwater sediment


K_(susp-water) = 1.88


RHO_(susp) = 1150


Conversion factor (wwt -> dwt): 4.6


 


PNEC_freshewater sediment


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


= (1.88/1150)* 0.00586* 1000


= 0.00958 mg/kg wwt


= 0.044 mg/kg dwt


 


PNEC marine water sediment


K_(susp-water) = 1.88


RHO_(susp) = 1150


Conversion factor (wwt -> dwt): 4.6


 


PNEC_marine sediment


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


= (1.88/1150)* 0.000586* 1000


= 0.000958 mg/kg wwt


= 0.0044 mg/kg dwt


 


PNEC soil


K_(soil-water) = 1.37


RHO_(soil) = 1700


Conversion factor (wwt -> dwt): 1.13


 


PNEC_soil


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


= (1.37/1700)* 0.00586* 1000


= 0.00472 mg/kg wwt


= 0.00534 mg/kg dwt

Conclusion on classification

Acute toxicity:


Algae is the most sensitive species to the acute toxic effects of the test item with an acute ErC50 of 1.417 mg/L. Based on the these data, the substance has not to be classified with regard to acute environmental toxicity according to Regulation (EC) No 1272/2008 (CLP/GHS).


 


Chronic toxicity:


Algae are the most sensitive species to toxic long-term effects of the test item with a chronic NOEC of 0.293 mg/L. As the test item is ready biodegradable, on the basis of the available toxicity data the substance is classified as chronic aquatic cat. 2 (H411: Toxic to aquatic life with long lasting effects) according to Regulation (EC) No 1272/2008 (CLP/GHS).
