Conclusion on classification

Being an inorganic substance, reaction mass of lanthanum phosphate and cerium phosphate and terbium phosphate is considered as not readily biodegradable. By analogy with other lanthanum, cerium and terbium compounds, a potential for bioaccumulation is not expected for the reaction mass. Finally, short-term tests performed on the three trophic levels (i.e. fish, daphnids, algae) do not reveal any acute toxicity up to and including the solubility limit into water. And the long-term data available on other insoluble compounds of cerium and lanthanum (i.e. cerium dioxide and lanthanum oxide) did not reveal any long-term effect on Daphnia reproduction and survival up to and including the water solubility limit; implying that a similar conclusion can be expected for reaction mass of lanthanum phosphate and cerium phosphate and terbium phosphate.

As a result, reaction mass of lanthanum phosphate and cerium phosphate and terbium phosphate is not classified regarding its environmental impacts, neither under the criteria of CLP, nor under those of DSD.
