**Preface to "Assessing Atmospheric Pollution and Its Impacts on the Human Health"**

In recent decades, due to industrial expansion and urbanization, atmospheric pollution has become one of the main threats to public health and natural ecosystems. The production of pollutants from different sources can easily be evaluated; however, their dissipation is associated with the mechanisms of diffusion and transport in various atmospheric conditions, with wind speed being one of the main influencing factors. The accumulation of pollutants is a stochastic phenomenon, depending on multiple factors such as atmospheric circulation, turbulence, wind direction and speed, air temperature, humidity, etc., making the assessment and forecasting of this phenomenon difficult. In conditions of atmospheric calm, the particles accumulate near the emission sources, increasing the time that the population is exposed to toxic substances which induce respiratory diseases and, sometimes, irreversible harm to human health. Therefore, assessing air quality is extremely important for maintaining a clean and healthy environment. In this context, the articles included in this collection addressed the following topics:

·Estimating the air quality using statistical and artificial intelligence methods;

·Modeling the extremes of different pollutants over various time series;

·Emphasizing the impact of atmospheric pollution on human health, especially the incidence of pulmonary diseases in highly polluted zones;

·Analyzing the carcinogenic and non-carcinogenic risks of exposure to different pollutants for an extended period.

The topic is of interest to scientists and the general public, addressing problems that we all face.

The editor would like to thank the authors for sharing the results of their research, and the reviewers whose valuable suggestions led to significant improvements to the submitted articles.

Last but not least, we thank the editorial staff who helped to ensure a smooth editorial process.
