Sting the soil mutagenic pollution of Orel's northern district using of Arabidopsis thaliana

The article presents the results of the analysis of the integral level of toxicity and mutagenicity of soils from 10 different places in the Northern region of Orel. Analysis of mutagenicity was performed using an embryo-test for Arabidopsis thaliana. Tester plants were grown in laboratory conditions on the soil of the collected samples. Morphological analysis of mutations was performed in the phase of fruiting. The frequencies of sterile eggs, dominant lethal (sicca, brevis, vana, diffusa, murca, parva, fusca) and recessive chlorophyll (albina, chlorina, xantha) mutations were taken into account. The soil of the two samples induced frequencies of embryonic lethal, which was statistically significantly different from the control. Three soil samples induced statistically significantly higher frequencies of sterile eggs. Six soil samples caused a statistically significant increase in the total frequencies of all analyzed anomalies. These results indicate that there are areas with a high content of mutagenic and phytotoxic pollutants in the Northern region of Orel.
