An acute toxicity test in fish is available
for cesium tetrafluoroaluminate. No other aquatic toxicity tests are
available for cesium tetrafluoroaluminate and therefore the results from
the structural analogue cesium fluoro aluminate complex are used instead
(for details see Reporting format
as attached to the respective
IUCLID entry and CSR Appendix A.2). For the structural analogue cesium
fluoro aluminate complex, reliable GLP
compliant aquatic acute ecotoxicity tests are
available for fish, invertebrates and algae, as
well as a respiration inhibition test with activated sludge. The
environmental effects are expected to be mostly governed by the presence
of fluoride anions formed upon dissociation of the fluoroaluminate
moieties. As the contents of fluoride, expressed as a
percentage of the molar weight in both substances are nearly identical,
namely 32% for cesium tetrafluoroaluminate and ca. 30% for
cesium fluoro aluminate complex, no correction was made for the
difference in molecular weight percentage.
No long-term aquatic toxicity tests are
