The aim of this study is to analyze the spread of gaseous and particulate pollutants in the atmosphere emitted by Edison Next Poland Sp. z o. o. in Tychy. The analyzed emitter is 150 m high and 2.6 m in diameter and is an open point source. The analysis covered 1-hour and annual average concentrations of NO2, SO2, and PM10 dust, as well as dust fall values throughout the year. The immission values were calculated using the Ek100W program from Atmoterm, which is based on the Pasquill’s model and is recommended by the Polish Ministry of the Environment for analyzing air quality in facilities with emitters. The results obtained were compared with the applicable standards, which made it possible to determine whether the operation of the installation entails a risk of exceeding air quality standards. The Ek100W pro-gram also allows for graphical visualization of the results in the form of concentration isolines (immission values) plotted on maps, which facilitated the analysis. Both in the case of 1-hour and annual average immission analyses and dust fall, it was found that the maximum values recorded in the calculation grid are mainly concentrated in the north-eastern area northeast of the emission source, which clearly indicates the dominant role of wind directions in shaping the spatial distribution of concentrations. Despite local increases, even the highest values of the calculated concentrations of NO2, SO2, and PM10 dust do not approach the permissible levels specified in the applicable regulations. A comprehensive interpretation of the results obtained allows us to conclude that the plant located in Tychy meets the requirements of applicable air protection regulations and does not pose a threat to human health or the natural environment. Low emission and immission levels are the result of the use of modern combustion technologies and effective solutions to reduce emissions of pollutants into the atmosphere. The results of the calculations also indicate the correctness of the calculation methodology used, based on the Pasquill equation, which allows for a reliable representation of the range and concentration of pollutants in the air.
