Mutagens cause mutations, which are changes in the DNA sequence of an organism. Mutations can lead to harmful effects, such as cancer or genetic disorders. Mutagens themselves may not be toxic, flammable, explosive, etc., but their ability to cause mutations is what makes them harmful. It is not necessarily true that they are fatal in low doses or that they cause other types of harm.
