Abstract
The performed experiments demonstrated that the needles of pine, under the conditions existing in Kemerovo, accumulates sulphur, nitrogen, phosphorus, calcium, magnesium, potassium, lead, copper, zinc, manganese, nickel, cobalt, iron. This causes an increase in the activity of peroxidase, cell membrane permeability, decrease in ascorbate level, appearance of visual indices of damage, which leads to a decrease in lifetime and in dry mass of the needles. An interconnection is revealed between the extent of deviation of the indicated parameters and the level of pollution in the regions of the city. A principal possibility to use the investigated characteristics of functional status of the assimilation system of pine in evaluating the quality of urban environment is demonstrated.
