In a reverse gene mutation assay in bacteria conducted similar to
OECD test guideline 471, strains TA98, TA100, TA1535 and TA1537 of
Salmonella typhimurium were exposed to Zirconium oxychloride hexahydrate
in 95% ethanol at concentrations of 10, 33, 100, 333, 1000, 3333 and
6666 µg/plate in the presence and absence of mammalian metabolic
activation. The positive controls induced the appropriate responses in
the corresponding strains. There was no evidence of induced mutant
colonies over background in all tester strains. Therefore, Zirconium
oxychloride hexahydrate is considered to be non-mutagenic in this
Salmonella typhimurium reverse gene mutation assay.
