Additional information
Study reports have been available for consideration in respect of acute tests with fish, invertebrates, algae and micro-organism. A PNECaquatic of 0.0072 mg/l has been derived from 7.2 mg/l (EL50 value-48 h) for effects on Daphnia acute toxicity test (the lowest short-term EL50 from each of three trophic levels (fish, Daphnia and algae)) by an assessment factor of 1000.
No measured data are currently available for intermittent releases therefore the intermittent releases PNEC is derived from data obtained for freshwater species (EL50 = 7.2 mg/l), applying an assessment factor of 100 to give PNECwater, intermittent = 0.072 mg/l.
The PNEC for STP is 1 mg/l based on the IC50 of 100 mg/l and an assessment factor of 100.
No toxicity data are currently available for sediment-dwelling organisms. However, according to the Technical Guidance Document, PNECsed (freshwater) can be calculated by the equilibrium partitioning method. Hence, PNECsed (freshwater) = 6.677 mg/kg will be used for risk characterisation.
For the PNEC in soil, no toxicity data are currently available; therefore, it is not possible to determine a PNECsoil based on measured data. According to the Technical Guidance Document, PNECsoil can be calculated by the equilibrium partitioning method. Hence, PNECsoil = 8,012 mg/kg will be used for risk characterisation.
For the atmosphere, No data are available on the toxicity to plants or other organisms exposed via air. Based on its structure, the test substance is not expected to have ozone depleting effects and the low level of exposure makes other effects unlikely.
In the marine environment, there was no measured data are currently available for marine organisms therefore the marine PNEC is derived from data obtained for freshwater species (EL50 = 7.2 mg/l), applying an assessment factor of 10000 to give PNECseawater= 0.00072 mg/l. In addition, there are no measured data currently available for marine sediment organisms and therefore, the PNEC is derived by the equilibrium partitioning method to give PNECmarine sediment = 0.6677 mg/kg.
Below table is the summary of the value of PNEC in each compartment.

Conclusion on classification
From the available information, the lowest short-term EC(L)50 from each of three trophic levels (fish, Daphnia and algae) was 7.2 mg/l loading rate WAF in Daphnia acute toxicity test and the substance was shown to rapidly degrade.
Therefore, it is not classified as per EU CLP (Regulation (EC) No 1272/2008) regulation.
