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).
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).
