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)
