[Environmental mutagenesis].

Mutagen agents may increase the genetic load of human populations by inducing heritable diseases and cancer. The most effective way of protection is prevention: detection of the mutagenic agents and the regulation of their use. The harm occurred can be visualized by mutational monitoring and epidemiology. The harmful effects of the induced mutations may be reduced to a level accepted by the society with suitable approach and methods. The role of physicians is especially important to fulfil this task.
