Additional information
PNEC freshwater sediment:
K_(susp-water) = 959
RHO_(susp) = 1150
Conversion factor (wwt -> dwt) = 4.6
PNEC freshwater sediment
= (K_(susp-water) / RHO_(susp)) * PNEC_water * 1000
= (959 / 1150) * 0.043 * 1000
= 35.858 mg/kg wwt
= 164.948 mg/kg dwt
PNEC marine water sediment:
K_(susp-water) = 959
RHO_(susp) = 1150
Conversion factor (wwt -> dwt) = 4.6
PNEC marine water sediment
= (K_(susp-water) / RHO_(susp)) * PNEC_marine water * 1000
= (959 / 1150) * 0.0043 * 1000
= 3.5858 mg/kg wwt
= 16.4948 mg/kg dwt
PNEC soil:
K_(soil-water) = 1.15E+03
RHO_(soil) = 1700
Conversion factor (wwt -> dwt) = 1.13
PNEC soil
= (K_(soil-water) / RHO_(soil)) * PNEC_water * 1000
= (1.15E+03 / 1700) * 0.043 * 1000
= 29.088 mg/kg wwt
= 32.8697 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 43 mg/L. Based on the this 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 12.5 mg/L and an EC50 of 43 mg/L. As the test item is not ready biodegradable, the substance is classified as chronic cat. 3 (H412: Harmful to aquatic life with long lasting effects) according to Regulation (EC) No 1272/2008 (CLP/GHS).
