Application of coniferous dendroforms for biotesting of coastal urban environments

Abstract

In the urban environment, the main sources of pollutants entering the atmosphere are the work of industrial enterprises and the operation of vehicles, which leads to a significant change in the composition of the air, which leads to the objective need for strict control of the state of the city’s environment and atmospheric air in particular. The ongoing state monitoring control of the atmospheric air in the urban environment is not sufficient, which leads to the need to create alternative control methods. This method is bioindication and biotesting. Applying the sensitivity of organisms, one can assess the degree of environmental pollution. Thus, the choice of certain bioindicators directly affects the quality of the data obtained, especially in the areas of coastal cities. The studies were carried out in Sevastopol during 2018-2020. The results obtained make it possible to use Pinus pallasiana Lamb. as a test object for assessing the quality of the environment. Coniferous dendroforms Picea pungens Engelm. and Thuja occidentalis L. showed results that allow their use in bioindication, in the case of using the entire possible spectrum of markers to increase the reliability of environmental quality assessment by biotesting methods. Previously, similar studies were carried out using deciduous dendroforms.
