Bioindicator assessment of air quality in Armizonskoye village, Tyumen region

Abstract:

In the town of Armizonskoye, Tyumen Region, Russia, industrial enter-prises emit more than 230 tons of various pollutants into the air, and only about 50% of that total is retained. In this work the quality of atmospheric air in Armizonskoye was studied using the bioindication method. The objectives of the study were to identify the main pollutants in the air and to deter-mine the most sensitive test functions of woody and herbaceous plants. The chemical method was used to determine the quantity and array of substances, emitted by some enterprises in different parts of the town. The bioindicators were common dandelion Taraxacum officinale Wigg, great plantain Plantago major L., warty birch Betula pen-dula Roth, and boxelder maple Aceraceae nequndo. The chemical analysis showed that the air is mainly polluted with iron oxide, manganese compounds, and suspended sol-ids. The main sources of pollution are utility companies, Armizonagrostroy, and road maintenance companies. The most sensitive indicator among woody plants was boxelder maple, and among herbaceous plants, com-mon dandelion. The bioindication method helped to map more and less polluted territo-ries.
