Ferrocene was assessed for its ability to induce gene mutations in an in vivo assay using mouse lymphoma L5178Y cells and conducted according to OECD Guideline 476.
It is concluded that dicyclopentadienyl iron did not induce mutation at the tk locus of L5178Y mouse lymphoma cells when tested under the conditions employed in this study. These conditions included four independent treatments at concentration up to 32 μg/ml in the presence (4 hours) of a rat liver metabolic activation system (at 1 and 2% (v/v) final concentration of S9 fraction) and at concentrations of 232.5 µg/ml and 2 μg/mL in the absence (4 and 24 hours, respectively) of metabolic S9. The maximum doses tested were limited by either acceptable reductions in toxicity (as measured by %RTG) or by precipitate (observed by eye) at the end of treatment in the absence or presence of S9, respectively.
