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

One reliable long term toxicity study (Klimisch 1, GLP) for a fish species -the zebrafish danio rerio - was conducted. No effect (mortality) was noted at the highest test concentration of nominal 100 mg barium dichloride dihydrate/L. Since the recovery rates (RR) of the analytical verification of the test material in test solution are < 80% the results are given as actual (geometric mean measured) concentrations.

(a) The NOEC >= 61.1 mg BaCl2/L (>= 40.3 mg barium/L) based on total barium concentration.

(b) The NOEC >= 1.91 mg BaCl2/L (>= 1.26 mg barium/L) based on dissolved barium concentration.
