Mapping of enviromental pollution of air in Lviv

Abstract

The condition and composition of air in Lviv are influenced by two main factors: the introduction of pollutants into the atmosphere through various sources and harmful physical effects on it. The latter includes radiation, sound vibrations, noise, and so on. These and other factors disrupt the optimal conditions of the air, which negatively affects human health and the condition and development of animals and plants. The main sources of pollutants in the air of Lviv are as follows: dust — vehicles, woodworking and building materials industry; sulfur dioxide — industrial enterprises, carbon monoxide — vehicles, thermal power plants; nitrogen dioxide — heat power companies; formaldehyde — motor transport, woodworking industry. Today, emissions from mobile sources are the biggest air pollutants in the city. The chemical composition of emissions from mobile sources of pollution is characterized by the predominance of carbon monoxide (up to 74 %), nitrogen compounds, and hydrocarbons (12 % and 11 %, respectively). Today the state of atmospheric air in large cities of Ukraine and, in particular, in the city of Lviv is at an unsatisfactory level. The main problems in this area are the progressive nature of the negative impact on the ecological state of the environment and human health. As there is currently no interactive cartographic material that can visualize the problem of environmental pollution, the main purpose of this work was to create an interactive web map of the quality of life of the population of Lviv in terms of air pollution. To achieve this goal, we collected and systematized geospatial statistical cartographic materials on the ecological conditions of the air in Lviv. The necessary software for the development of an interactive map of air pollution has been selected, and its possibilities have been studied. An algorithm for loading geospatial data into the created web resource has been developed. A template of applications for creating web maps of air pollution in Lviv was selected according to the indicators of 2020, which were measured at 30 crossroads of the city. Thus, two interactive web maps of air pollution in Lviv were developed in the environment «Google My Maps» and «ArcGIS Online».
