The first link on a biochemical level to which exposure to toxic agents, are the chloroplasts. Changes in the content of pigments, specifically, chlorophyll, used as an indicator reaction damage occurring under the influence of air pollutants. A determination of ascorbic acid content, taking part in the most important energetic processes of the plant cell - photosynthesis and respiration. It is shown that the levels of ascorbic acid can serve as a test characterizing the stability and adaptive capacity of plants. The content of ascorbic acid in spruce varies from 4.7 to 15.3% in pine from 3.6 to 14.7%, larch from 3.5 to 7.8%.
