Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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
Sulfide:
As sulfides do not have a potential for bioconcentration/bioaccumulation, secondary poisoning is not relevant. However, data available for pigs (Cromwell, 1979) support this lack of potential for secondary poisoning. In this study, the addition of sulfide to the diet (nominal 450 ppm Na2S) did not affect rate or efficiency of weight gains and food efficiency as well as haemoglobin and hematocrit values.
Barium:
Reliable and relevant studies (Dietz, 1992 and NTP, 1994) for repeated-dose toxicity to small mammals (rats and mice) via the oral route are available for expsoures lasting up to 2 years. The lowest NOAEL (1124 mg/L Ba; 61.1 mg Ba/kg bw/day) was observed in a study with male rats (Fischer 344) exposed via drinking water to Barium dichloride dehydrate for 92-days (Dietz, 1992).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
