Additional information

PNEC Freshwater and marine sediment:

Ksusp-water = 3.16

RHOsusp = 1150

PNEC_freshwater sed. = (K_susp-water / RHO_susp) * PNEC_water * 1000

= (3.16 / 1150) * 0.0857 * 1000

= 0.2355 mg/kg wwt

= 1.083 mg/kg dwt

PNEC_marine sediment = (K_susp-water / RHO_susp) * PNEC_marine water * 1000

= (3.16 / 1150) * 0.00857 * 1000

= 0.02355 mg/kg wwt

= 0.1083 mg/kg dwt

PNEC soil:

Ksoil-water = 3.6

RHOsusp = 1700

PNECsoil = (K_soil-water / RHO_susp) * PNEC_water * 1000

= (3.6 / 1700) * 0.0857 * 1000

= 0.1815 mg/kg wwt

= 0.2051 mg/kg dwt

Conclusion on classification

Acute toxicity:

Fish is the most sensitive species to the acute toxic effects of the test item with an acute LC50 of 85.7 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), as amended for the tenth time in Regulation (EC) 2017/776.

Chronic toxicity:

Only one long-term test is available - toxicity to algae. Based on the fact that the test item is not readily biodegradable and the obtained results from the aquatic tests, the substance is classified as Long-term (Chronic) Environmental Toxic Category 3 (H412: Harmful to aquatic life with long lasting effects.) according to Regulation (EC) No 1272/2008 (CLP/GHS), as amended for the tenth time in Regulation (EC) 2017/776.
