According to the results of the correlative modeling regression, there is a strong correlation link between the concentration of harmful substances in the atmosphere and the amount of tree accumulation in the leaves. Such bonding was most prominent at juniper trees. In particular, the density of binding between the two sulphate proteins and the accumulation of this substance in the leaf of selected trees was 0.88 in the juniper tree, 0.78 in the oak tree, 0.75 in the chestnut, and 0.93 in the pavlonion tree.
