Additional information
PNEC freshwater sediment
K_(susp-water) = 1.87E+03
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshewater sediment
= (K_(susp-water) / RHO_(susp)) * PNEC_water * 1000
= (1.87E+03/1150) * 0.001 * 1000
= 1.62 mg/kg wwt
= 7.48 mg/kg dwt
PNEC marine water sediment
K_(susp-water) = 1.87E+03
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine sediment
= (K_(susp-water) / RHO_(susp)) * PNEC_marine water * 1000
= (1.87E+03/1150) * 0.0001 * 1000
= 0.162 mg/kg wwt
= 0.748 mg/kg dwt
Conclusion on classification
Acute aquatic toxicity:
Daphnia were the most sensitive species in acute aquatic toxicity tests with Aldehyde L, according to EU method C.2 and OECD guideline 202, resulting in an 48h-EC50 of 1.02 mg/L. In addition, the EC50 values for algae and fish have shown to be over 1 mg/L. Based on acute aquatic toxicity results obtained, Aldehyde L was not classified and labelled for short-term (acute) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) 2020/1182.
Chronic aquatic toxicity:
Aldehyde L was tested in an aquatic toxicity test with algae, according EU-method C.3 and OECD guideline 201. The 72-hour EC50 for growth rate was over 1 mg/L and the 72-hour NOEC was determined to be 0.18 mg/L. In addition, Aldehyde L was shown to be ready biodegradable. Thus, the substance has to be classiffied for long-term (chronic) aquatic toxicity in cat. 3 according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) 2020/1182.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
