Conclusion on classification

Classification

Cerium trichloride is not considered to be biodegradable due to its inorganic nature. Furthermore, the substance is not considered to be bioaccumulative based on bibliographic data on fish, the preferred REACH-species to assess bioaccumulation potential. Short-term toxicity tests showed that the substance is very toxic to fish and harmful to daphnia, with a lowest effect concentration being a 96-h LC50 of 0.13 mg Ce/L for rainbow trout, corresponding to a 96-h LC50 of 0.23 mg CeCl3/L. Taking into consideration the acute test results together with environmental fate data and in accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the test material is classified as follows:

Aquatic acute 1 (H400) - M-factor 1

Aquatic chronic 1 (H410) - M-factor 1

According to the Dangerous Substance Directive 67/548/EC (Annex VI, section 5.2.1.2), the substance should be classified as N, R50/53.
