Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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)
