Additional information

PNEC freshwater sediment:

K_(susp-water) = 2.6

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

 

PNEC_freshwater sediment

= (K_(susp-water)/ RHO_(susp))*PNEC_water * 1000

= (2.6/1150)* 3.0E-04 *1000

= 6.8E-4 mg/kg wwt

= 3.12E-3 mg/kg dwt

 

PNEC marine water sediment:

K_(susp-water) = 2.6

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

PNEC_marine water sediment

= (K_(susp-water)/ RHO_(susp))*PNEC_marine water* 1000

= (2.6/1150)*3.0E-05* 1000

= 6.8E-5 mg/kg wwt

= 3.12E-4 mg/kg dwt

 

PNEC soil:

K_(soil-water) = 2.24

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

 

PNEC_soil

= (K_(soil-water)/ RHO_(soil))*PNEC_water * 1000

= (2.24/1700)* 3.0E-04* 1000

= 3.95E-4 mg/kg wwt

= 4.48E-4 mg/kg dwt

Conclusion on classification

Acute toxicity:

Freshwater algae (diatom) are the most sensitive species to the acute toxic effects of the test item with an acute EC50 of 0.1 mg/L. Based on the these data, the substance has to be classified with regard to acute environmental toxicity with aquatic acute cat. 1 (H400: Very toxic to aquatic life, M = 10) according to Regulation (EC) No 1272/2008 (CLP/GHS) and as N, R50 (Dangerous for the environment; Very toxic to aquatic organisms.) according to Directive 67/548/EEC (DSD).

 

Chronic toxicity:

Classification of the test item is based on long-term toxicity data. Freshwater algae (diatom) are the most sensitive species to toxic long term effects of the test item with a chronic NOEC of 0.003 mg/L. As the test item is not ready biodegradable, the substance is classified as chronic aquatic cat. 1 (H410: Very toxic to aquatic life with long lasting effects, M = 10) according to Regulation (EC) No 1272/2008 (CLP/GHS) and as N, R50/53 (Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment) according to Directive 67/548/EEC (DSD).
