BIOLOGICAL MONITORING OF SMALL RIVERS
At the present stage of development of society anthropogenic load has a significant impact on ecosystems. High levels of heavy metal pollution can exceed the adaptive capacity of living organisms and can lead to metabolic regression. The most important component of environmental monitoring of the environment is biomonitoring - a system of observation, assessment and prediction of various changes in the biota caused by factors of anthropogenic origin. Biomonitoring makes it possible to directly assess the quality of the environment and is one of the levels of the sequential process of studying the health of the ecosystem. As part of our article, we conducted a study that was aimed at studying the influence of water from the river om, recruited in different time frames and in different places in the city of Omsk and its surroundings, on the germination of radish seeds. The lowest germination is observed at the site near the lubinsky bridge in the spring -81.1 %, a little more germination in the autumn - 85.5 %. Samples with the control variant in radish seeds showed 90.1 %, the area between 17 and 18 lines-86.6 %. The result of the Steppe settlement was 81.7. The analysis of the obtained data confirms the impact of the om river samples on the germination of radish seeds.
