Additional information
Aquatic toxicity:
No reliable experimental data are available regarding aquatic toxicity of 2-methylquinoline.
To assess the aquatic toxicity of 2 -methylquinoline predicted values by ECOSAR v.1.11 are used:
LC50 96h fish = 34.723 mg/l
LC50 48h Daphnid = 20.820 mg/l
EC50 96h green algae = 19.427 mg/l .
In literature there are some experimental data for 2-methylquinoline regarding acute toxicity on fish (LD50 24h < 143 mg/L reported by ECOTOX with reference to Brown et all, Comp. Biochem Physiol., p.223-231, 1972) and regarding growth inhibition rate of ciliate protozoa Tetrahymena pyriformis (IG50 72h = 48.7 mg/l reported by ECOTOX with reference to Schultz et all, Arch. Environm. Contam. Toxicol.9, p.591-598,1980).
ECOTOX reports also a study regarding toxicity on amphibia for 2 -methylquinoline (LC50 96h= 26.4 mg/l, Xenopus laevis (anfibo) with reference to Dumont et all, Bull. Environ. Contam. Toxicol.22(1-2), p. 159-166, 1979). The data reported by ECOTOX for 2-methylquinoline don't allow to assess an aquatic classification for the substance but they support the predicted data by ECOSAR v 1.11. In fact, the experimental data reported by ECOTOX are in the same range of magnitude of predicted data by ECOSAR.
Based on data predicted by ECOSAR v 1.11 for acute aquatic toxicity considering that the substance is predicted as not ready biodegradable and based on precautionary principle, the classification H412 (long term aquatic toxicity cat.3) is proposed for 2-methylquinoline according to CLP Regulation (EC n.1272/2008).
Sediment toxicity
No data available.
Terrestrial toxicity:
No data available.
Conclusion on classification
Based on data predicted by ECOSAR v 1.11 for acute aquatic toxicity considering that the substance is predicted as not ready biodegradable and based on precautionary principle, the classification H412 (long term aquatic toxicity cat.3) is proposed for 2-methylquinoline according to CLP Regulation (EC n.1272/2008).
