Additional information

The lowest NOEC was found to be in algae and was taken from the Noack (1992) study. this endpoint is also used in the EU RAR 2005 for deriving the PNEC. the data that was used are longterm fish, long term daphnia and an algae NOEC. the assessment factor to be used according to EU TGD therefore is 10. this results in a PNEC aquatic of 0.58 ug/L.

Data was used from MCA and SMCA together since in the environment the sodium salt disassociates rapidly due to intrinsic properties (see EU RAR 2005).
