Additional information

Short-term toxicity of allyl alcohol to freshwater fish, invertebrates and algae has been determined experimentally. Fish proved to be the most sensitive indicator of toxicity and hence the 96h LC50 value for Pimephales promelas was used as the critical value for calculation of PNEC values for freshwater and marine organisms. The PNEC for STP microbes was calculated from an OECD 301C guideline ready biodegradation study which suggested no evidence of inhibition of microbial inoculum at a concentration of 100 mg/l allyl alcohol. No data were available for allyl alcohol to evaluate sediment toxicity and so the sediment PNEC (for freshwater and marine) were generated using the Equilibrium Partition Method in combination with the derived freshwater PNEC. Short-term terrestrial toxicity data was evaluated and the lowest EC50 obtained from short-term plant toxicity study (L. sativa) was used to derive the soil PNEC.

Conclusion on classification

Based on the LC50 result in the 96h acute toxicity to fish test (0.32 mg/l) and confirmation of being readily biodegradable, the classification of allyl alcohol is concluded to be:

- under Directive 67/548/EEC criteria, N; R50

- under Regulation 1272/2008 (CLP GHS) criteria, acute aquatic hazard category 1

- under UN GHS criteria, acute aquatic hazard category 1

Based on the NOEC from the 21 -day-chronic toxicity of allyl alcohol to Daphnia magna, the NOEC was identified as 0.919 mg/l based on the inhibited rate of reproduction. The classification of allyl alcohol is concluded to be:

- under Regulation 1272/2008 (CLP GHS) criteria, chronic aquatic hazard category 3
