Additional information

Conclusion on classification

Not classified according to Regulation (EC) No 1272/2008 classifiable based on the fact that short term toxicity data are >100 mg/L. In addition, the NOEC for long term toxicity with invertebrates is >1 mg/L therefore Na4-HEDP is not classified for the environment.
