Additional information

All PNECs are derived using the standard approach as indicated by the "Guidance on information requirements and chemical safety assessment Chapter R.10: Characterisation of dose [concentration]-response for environment" (ECHA, 2012. Several studies on acute toxicity to aquatic species are available for all trophic levels. In most cases the endpoints of the aquatic toxicity tests were based on nominal concentrations.

The lowest available NOEC was found in a Fish Early Life Stage test with Zebra fish Danio rerio based on initial test concentrations of 0.00094 mg/L (Scheerbaum, 2007). Although this study is per se not a long-term study, an effect level for development was derived. The lowest available short-term EC50 was found in invertebrates with a value of 0.16 mg/L from a test with Pseudokirchneriella subcapitata (Hicks, 1996). The lowest available EC50 of 320 mg/kg dry soil based on the nominal concentration is from the seedling emergence test with non target plants Brassica napus (Fiebig, 2007). The lowest available EC50 of micro-organisms in the activated sludge is 5.1 mg /L (De Groot and van Dijk, 2001).

Conclusion on classification

The available data on aquatic toxicity of peracteic acid meet the criteria for classification as Aquatic Acute 1 (H400; M = 1) at concentration >= 25% and Aquatic Chronic 1 (H410; M = 10) at concentration >= 2.5%, Aquatic Chronic 2 (H411; M = 2) at concentrations 0.25% - < 2.5% and Aquatic Chronic 3 (H412; M = 10) at concentration 0.025 -< 0.25% according to Regulation (EC) 1272/2008, respectively.
