Morphological changes occur in the leaves of trees under the influence of various air pollutants. Recording and assessing these changes reflects the state of the environment. The aim of the study was to assess the level of air pollution in the city of Kineshma, Ivanovo region, using the bioindication method. The technique of morphometry of pedunculate oak leaves and calculation of the index of fluctuating asymmetry were used. In all points of the city, a high asymmetry of oak leaf blades was noted, which indicates a critical level of atmospheric pollution. Ecotoxicants contained in emissions from enterprises and vehicles significantly violate the bilateral symmetry of oak leaf blades.
