Conclusion on classification
Classification
Barium nitrate is not considered to be biodegradable due to its inorganic nature. Furthermore, the substance is not considered to be bioaccumulative based on the available data for fish, i.e. the preferred REACH taxonomic group to assess bioaccumulation potenital. Short and long-term toxicity tests are available for 3 trophic levels. The acute EC50 and LC50 values are situated between > 1.15 mg Ba/L (algae) and 14.5 mg Ba/L (daphnids), corresponding to > 2.19 and 27.6 mg Ba(NO3)2/L, respectively. In accordance with the criteria for classification for short-term effects in the aquatic environment as defined in Annex I, Regulation (EC) No 1272/2008, classification for acute aquatic hazard is not required for barium nitrate as all EC50/LC50 values are above the classification criterion of 1 mg/L. The long-term NOEC and EC10 values range from >= 1.15 mg Ba/L (algae) to 2.9 mg Ba/L (daphnids), corresponding to >= 2.19 and 5.52 mg Ba(NO3)2/L, respectively. In accordance with the criteria for classification for long-term effects in the aquatic environment as defined in Annex I, Regulation (EC) No. 1272/2008, the test material is not classified for long-term aquatic hazard as all NOEC/EC10 values are above the classification criterion of 1 mg/L.
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.
