The atmosphere is one of the environmental components, which living organisms utilize the most. However, in large urban agglomerations, the air often contains substances that can be dangerous to human health and ecosystems, especially if their concentrations exceed the legal norms. Although the mechanism of impact of the individual chemical compounds (SO2, NO2, O3, benzene, etc.), considered as pollutants is well known, it is still a challenge to clarify the composition and impact of the particulate matters, espec...

The rapid development and industrialization in recent years have posed a great challenge to the environment and air quality due to the increased anthropogenic emissions of particulate matter. Both PM2.5 and PM10 (particulates with aerodynamic diameters equal or less than 2.5 and 10 ?m, respectively) have become the forefront focus due to their adverse effect on human health and climate. Therefore, the assessment of chemical composition of PM2.5 and PM10 defining in general their toxicity and its correlation with m...
