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.

Description of key information

Juvenile Zebrafish were exposed in a 96 h static test according to OECD guideline 203 to aqueous test media containing the test item at various concentrations. A full dose response study - 100, 45.5, 20.7, 9.4 and 4.3 mg/L test item – was performed. The study encompassed 6 treatment groups (5 dose rates and a control) each containing 7 individuals. The recorded effects were mortality and sublethal effects on the fish.

In the control and at the concentrations up to 4.3 mg test item/L, all fish survived until the end of the experiment and no signs of intoxication occurred. At 9.4 mg/L one fish died and at 20.7 mg/L three fish died after 96 hours. At 45.5 mg/L two fish died and at 100 mg test item/L three fish died after 96 hours. Based on these test results the following dose descriptors were determined:


LC50 (96 h) > 100 mg/L

LOEC (96 h) = 20.7 mg/L

NOEC (96 h) = 9.4 mg/L
