Additional information

PNEC freshwater sediment:

K_(susp-water) = 1

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

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

= (1/1150) * 9.45 * 1000

= 8.22 mg/kg ww

= 37.80 mg/kg dw

The PNEC (sediment-freshwater) of dry weight (dw) of lithium phosphate is 37.8 mg/kg corresponding to the wet weight (ww) value of 8.22 mg/kg (conversion factor: 4.6).

PNEC marine water sediment:

K_(susp-water) = 1

RHO_(susp) = 1150

Conversion factor (wwt -> dwt): 4.6

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

= (1.11/1150) * 0.945 * 1000

= 0.82 mg/kg ww

= 3.78 mg/kg dw

The PNEC (sediment-marin) of dry weight (dw) of lithium phosphate is 3.78 mg/kg corresponding to the wet weight (ww) value of 0.822 mg/kg (conversion factor: 4.6).

PNEC soil:

K_(soil-water) = 0.325

RHO_(soil) = 1700

Conversion factor (wwt -> dwt): 1.13

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

= (0.325/1700) * 9.45 * 1000

= 1.81 mg/kg ww

= 2.04 mg/kg dw

The PNEC (soil) of dry weight (dw) of lithium phosphate is 2.04 mg/kg corresponding to a wet weight (ww) value of 1.81 mg/kg (conversion factor: 1.13).

Conclusion on classification

Classification for Lithium phosphate
Based on the available data, lithium phosphate has not to be classified according to Regulation (EC) No 1272/2008 (CLP) criteria as the acute (LC50/ ErC50) and chronic toxicity (ECx/ NOEC) values are > 1 mg/L.

Overview of results used for Classification and Labelling of lithium phosphate
Based on read-across
Fish (Oncorhynchus mykiss), short-term, freshwater: LC50 = 31.65 mg/L (read-across from lithium carbonate)
Fish (Danio rerio), long-term, freshwater: NOEC = 15.96 mg/L (read-across from lithium hydroxide monohydrate)
Daphnia magna, short-term, freshwater: EC50 = 34.68 mg/L (read-across from dilithium carbonate)
Daphnia magna, long-term, freshwater: NOEC = 9.45 mg/L (read-across from lithium)
Algae (Desmodesmus subspicatus), long-term, freshwater: NOEC = 52.24 mg/L (read-across from lithium carbonate)
