| When it comes to carcinogens and toxins, for example, Priceless assumes that there is no safe threshold. |
| Several varieties of the mould Aspergillus produce a group of carcinogens called aflatoxins, which cause liver injury and cancer. |
| The tar in tobacco contains hundreds of carcinogens that promote the transformation of normal cells into cancerous cells. |
| In this way, ellagic acid effectively increases detoxification of carcinogens and reduces mutagenesis and tumourigenesis. |
| The insect-resistance gene discourages the build up of mycotoxins, potentially dangerous toxins that are probable human carcinogens, in corn. |
| For carcinogens and most reproductive toxins, however, regulators assume no threshold. |
