mutagen

Any agent capable of changing the structure of DNA without immediately killing the cell concerned. Any surviving MUTATION may be perpetuated to all descendants of the cell. Mutagens include ionizing radiation such as ultraviolet light, X-rays, gamma rays and cosmic rays and a wide range of chemical substances including the tars in cigarette smoke.

At levels of 10-50 ppb, or the equivalent of 10-50 micrograms per kilogram, the substance must show absence of genotoxicity after three standard mutagenicity tests. Substances above 50 ppb should be rejected unless a full toxicological profile of them has been evaluated.
