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

The toxic potential of the substance to fish (Brachydanio rerio) is evaluated according to the ISO7346 -1. The concentrations to be tested in the main study were selected based on a range-finding test in which three fish were exposed to five concentrations of the substance (200 -100 -50 -25 -10 mg/l). In the main test seven fish were exposed to 50 -30 -25 -20 mg/l of the substance for 96 hours during which fish were observed for mortality. Negative and positive control run in parallel. Mortality, pH, temperature and oxygen concentration every 24 hours. Concentrations of the substance were measured at the beginning and at the end of the test.

The LC50 determined at 96 h is 1.614 mg/l based on measured concentrations.
