It was conducted the comparative study of some morphological, physiological and biochemical indices of leaves of Tilia cordata Mill., Populus tremula L., Salix fragilis L., Salix alba L. from different habitats of Arzamas, characterized by different levels of contamination. It was found that the increase of technogenic load in the atmosphere led, amid increasing necrotization, to the decrease in the surface of leaves, reduction in their photosynthetic pigments – chlorophylls and carotenoids, change the structure of the light-harvesting complex in the direction of increasing the relative proportion of the yellow pigments, increasing the total ash content of the tissues of these organs. The most resistant to contamination are appeared T. cordata, S. fragilis and S. alba.
