The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

In a non-standard aquatic semi-static long-term juvenile growth assay conducted in Danio rerio, Ammonium Perchlorate was characterised by 4- and 12-week (chronic) NOECs of 10 mg/L Perchlorate ion for standard endpoints (mortality, growth, general condition, behavior) as well as whole-body T4 levels. The corresponding Ammonium Perchlorate NOEC was 12 mg/L.

The 12-week LOEC was 0.01 mg/L Perchlorate ion for colloidal T4 ring intensity (decreased), a very sensitive marker of T4 depletion. The corresponding Ammonium Perchlorate LOEC was 0.012 mg/L. This effect on a non-required endpoint is not considered for PNEC derivation in absence of effect on whole-body T4 levels and because hormones are not ecotoxicologically considered endpoints.
