Additional information
PNEC freshwater sediment
K_(susp-water) = 40.9
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshewater sediment
= (K_(susp-water) / RHO_(susp)) * PNEC_water * 1000
= (40.9 / 1150) * 0.0064 * 1000
= 0.228 mg/kg wwt
= 1.047 mg/kg dwt
PNEC marine water sediment
K_(susp-water) = 40.9
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine sediment
= (K_(susp-water) / RHO_(susp)) * PNEC_marine water * 1000
= (40.9 / 1150) * 0.00064 * 1000
= 0.0228 mg/kg wwt
= 0.1047 mg/kg dwt
PNEC soil
K_(soil-water) = 71.2
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil
= (K_(soil-water) / RHO_(soil)) * PNEC_water * 1000
= (71.2 / 1700) * 0.0064 * 1000
= 0.268 mg/kg wwt
= 0.3029 mg/kg dwt
Conclusion on classification
Acute toxicity:
Aquatic invertebrates are the most sensitive species to the acute toxic effects of the test item with an acute EC50 of 9.5 mg/L. Based on the these data, the substance has not to be classified with regard to short-term (acute) environmental toxicity according to Regulation (EC) No 1272/2008 (CLP/GHS).
Chronic toxicity:
Classification of the test item is based on long-term toxicity data.
Aquatic invertebrates are the most sensitive species to toxic long-term effects of the test item with a chronic NOEC of 0.32 mg/L. As the test item is not ready biodegradable, the substance is classified as Chronic Environmental Toxic Category 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.
