    Summary
    This summary is machine-generated.

    Assessing mutagenic risk requires careful method selection. Mammalian germ cell tests, like dominant lethal and spermatogonial tests, offer the most accurate human risk estimations.

    Main Results:

    • Mammalian germ cell tests provide more accurate human risk data than in vitro methods.
    • The dominant lethal test (mice) and spermatogonial test (Chinese hamsters) are highly suitable.
    • Method selection is critical for accurate mutagenic risk conclusions.

    Conclusions:

    • Industrial toxicologists must select precise methods for risk assessment.
    • Development of new, experience-based methods is encouraged.
    • Mammalian germ cell assays are superior for predicting human mutagenic dangers.
