Determination of air pollutionThe main sources of atmospheric air pollution in the Novosibirsk region for many years have been enterprises of the industry of production, transmission and distribution of electricity, gas, steam and hot water and automobile transport. According to the information of state report "On the state and environmental protection of the Novosibirsk Region in 2021", the share of pollution from thermal power facilities was 41.3%, and from cars 32.1% [1, p. 10].To determine the air pollution, research of the snow cover was carried out, which accumulated pollution over a period. It is logical that the closer to the road, the greater pollution from automobile exhaust.A bioindicator – watercress was used to analyze snow. Watercress, a plant of the genus Cruciferous. It has good sensitivity to pollution, fast germination, small size.Methodology of the experimentSnow sampling was carried out at several points in the open place and in the pine forest: near the highway, 10 meters from the road, 25 meters and 50 meters away. Then the snow was placed in numbered containers.Then the meltwater was used to be tested samples for toxicity. 50 watercress seeds were placed in Petri dishes on a filter paper soaked in melted water. Distilled water was used as a control. Watercress of the Dansk variety, LLC "Dachnaya Akademiya"When observing the seedlings, the number of germinated seeds was taken into account on the 3rd and 7th day after the beginning of the experiment, samples were compared in the forest and in the open area, the results were entered in the table.
