Additional information

One experimental ecotoxicological study on aquatic invertebrates and three read across predictions for short-term toxicity to algae, invertebrates and fish are available. 

 

In the experimental study adverse effects were observed in Daphnids, but the presence of severe limitations due to analytical issues prevented the quantification of the effect concentration levels. However, based on the immobility data (100% immobility at the saturated solution, 0% immobility at the 10% dilution of the saturated solution) and considering that the saturated concentration is expected to be between 2 and 6.5 mg/L ( basing on the solubility of MOVE 3 in water, estimated to range between 2.4 and 6.2 mg/L), the EC50 of MOVE for D.magna is estimated to be in the range 0.2 - 6.5 mg/L. This is consistent with the read across prediction, where the EC50 value for D.magna is predicted to be > 0.312 mg/L.


The estimated EC50 values for fish and algae are respectively  > 0.52 mg/ and > 0.23 mg/L suggesting that the three trophic levels have the same sensitivity to MOVE 3. 


In conclusion, MOVE 3 is expected to have toxic effects on aquatic organisms with EU GHS hazard class from "toxic" to "very toxic" to aquatic organisms.


No data of sediment and soil toxicity are available. Moreover, because of the high tendency to quickly volatilize and the expected analytical issues testing sediment and soil is expected to be technically unfeasible.



In any case, it should be underlined that, if released to the environment, basing on a qualitative assessment of the physical and chemical properties the main environmental compartment of distribution of MOVE 3 is anticipated to be the atmosphere while no significant distribution of MOVE3 to water, sediment and soil is expected therefore MOVE 3 is not expected to remain in water, sediment and soil in significant concentrations and long enough for arising significant effects to the organisms.



Conclusion on classification

MOVE 3 has been identified to be toxic to very toxic to the aquatic organisms on the basis of the biological data reported on daphnids and read across predictions for short-term toxicity to algae, invertebrates and fish.


Being no exact EC50 values available, and considering that MOVE 3 is not ready biodegradable, it is classified in the more stringent hazard class for aquatic environment according to EU GHS criteria:


Aquatic Acute Category 1


Aquatic Chronic Category 1


 


As the EC50 values for all the three trophic levels are above 0.1 mg/L, the following M factors are set:


M factor acute = 1


M factor chronic = 1
