Bioindication and biomonitoring assessment of the state of atmospheric air and soil in the study area

Abstract

Monitoring of the natural environment and human habitat must be carried out to compare the ecological state of the contaminated area and places that are not subject to technogenic impact. The main purpose of this work is to assess the state of the atmosphere, hydrosphere and soil using bioindication and biomonitoring methods. Phytotoxicity is the property of the soil to inhibit the growth and development of higher plants due to its contamination with xenobiotics and other toxic substances. In this work, the phytotoxicity of the soil is determined during the experiment on germinating of cucumber and dill seeds. The number of germinated seeds is calculated on differentially polluted soils. A comparative analysis of the of seedlings length and mathematical processing of lengths seedlings data, depending on the level of soil contamination, are carried out.
