Additional information

PNEC sediment (freshwater), PNEC sediment (marine waters), PNEC soil

No toxicity tests with sediment dwelling or terrestrial organisms are available. Thus, in accordance with the Guidance on information requirements and chemical safety assessment, Chapter R.10: Characterisation of dose [concentration]-response for environment, 2008, the PNEC for freshwater and marine water sediment as well as the PNEC soil have been calculated with the equilibrium partitioning method using EUSES 2.2. The following data have been taken into account for calculation: 

 

LC50 (fish)

> 17 µg/L (limit test)

NOEC fish

312.5 µg/L

EC50 (daphnia)

31.3 µg/L

NOEC (daphnia)

125 µg/L

EC50 (algae)

99 µg/L

EC10 (algae)

44.5 µg/L

Molecular weight

ca. 519 g/mol

Melting point

45°C

Vapour pressure

4.26E-4 at 20°C

Water solubility

1.25 mg/L at 23°C

Log Kow

Kp (solids-water in soil)

10000 L/kg

Kp (solids-water in sediment)

10000 L/kg

Kp (solids-water in suspended matter)

Kp (solids-water in sewage sludge)

Conclusion on classification

The most sensitive species was algae. The EC10 of the target substance was 0.0445 mg/L. This value is used to derive the PNECs.

 

The substance is not readily biodegradable. The measured BCF for the closely related substance DODMAC is 13 L/kg and therefore the bioconcentration potential is very low. The bioaccumulation criterion (BCF >= 100 L/kg) is not fulfilled.

Therefore, based on the results above Quarternary ammonium compounds, tri-C8-C10-alkylmethyl, Me sulfates is classified as Aquatic acute category 1 (M-factor 10) and Aquatic chronic category 1 (M-factor 1) in accordance with Regulation EC No 1272/2008.
