EC number: 263-372-5
CAS number: 62010-10-0
Short-term toxicity to fish:
Based on read across from zirconium dioxide, another insoluble zirconium
compound, zirconium basic sulfate is not expected to cause adverse
effects in fish at the limit loading rate of 100 mg/L.
Short-term toxicity to aquatic invertebrates:
Based on read across from zirconium dioxide and zirconium basic
carbonate, two other insoluble zirconium compounds, zirconium basic
sulfate is not expected to cause adverse effects in fish at the limit
loading rate of 100 mg/L.
Long-term toxicity to fish and aquatic invertebrates:
As zirconium basic sulfate is not classified for any endpoint, exposure
assessment and risk characterization according to REACH Annex I do not
need to be conducted. In view of the lack of effects in the available
acute aquatic toxicity tests (performed with other insoluble zirconium
substances), the extremely low water solubility of the substance, and
the known tendency of zirconium to form complexes with various ligands
in the aqueous environment (and thus to become completely
non-bioavailable), there is no need to investigate further the effects
on aquatic organisms. Based on this justification, these endpoints are
Toxicity to aquatic algae and cyanobacteria:
In the absence of a study on zirconium basic sulfate itself a weight of
evidence approach was proposed using two studies with other insoluble
zirconium compounds (zirconium basic carbonate and a reaction mass of
zirconium dioxide and cerium dioxide). In both studies, the observed
growth inhibitory effects were attributed to phosphate depletion.
Zirconium forms strong complexes with phosphate and therefore, when in
excess, precipitates all phosphate from the test medium. No evidence has
been found for direct toxic effects to occur to algae upon exposure to
zirconium compounds. The phosphate depletion effect in limited systems
such as used during aquatic ecotoxicity tests is not considered
environmentally relevant and therefore the tested zirconium compounds,
as well as zirconium basic sulfate, are not considered toxic to algae.
Toxicity to microorganisms:
No reliable studies were available for this endpoint.
Microorganisms in an STP will not be exposed to zirconium basic sulfate,
as it will either be removed in the primary settling tank before
reaching the microorganisms, or it will not be bioavailable due to
complexation. In addition, testing is waived based on the following
justification in accordance with REACH Annex VIII, 9.1.4 Column 2: the
study does not need to be conducted if the substance is highly insoluble
