[An evaluation of the mutagenic activity of the air pollutants in the area of a plant for the manufacture of synthetic rubber by using Tradescantia (clone 02) as the test object].

The mutagenic effects of atmospheric pollutants of synthetic rubber works on the frequency of point mutations in somatic cells of stamen hairs (CSH) of Tradescantia (clone 02) was studied under the condition of functioning or nonoperating shops. It was shown that temporary stopping of shops led to a decrease in the number of recessive mutations in CSN to the level 1.5 times higher than the control one. It increased during shop functioning to 0.21%. The cells moving off from the source of pollution led to a decrease in mutation frequency. The changes in the frequency of genetically indefinite mutations and morphological traits were also registered.
