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)* 0.01417* 1000

= 0.0231mg/kg wwt

= 0.106 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)* 0.001417* 1000

= 2.31E-03 mg/kg wwt

= 0.0106 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)* 0.01417* 1000

= 0.0114 mg/kg wwt

= 0.0129 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 not ready biodegradable, on the basis of acute 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).
