Air quality in the Moravian-Silesian Region and especially in the Ostrava agglomeration represents a very important factor influencing the environment and health of the local population. The area has been burdend for more than two centuries with rapid development of the mining industry and related metallurgical and chemical production. As a result, hundreds of tons of pollutants have progressively been released into the atmosphere. Some of them have been gradually eliminated from the environment; others, such as some heavy metals, remain locally present and burden the local landscape. Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air and an acknowledged risk to human health. Therefore, recurrent situations when statutory limits for airborne dust and selected chemical pollutants are exceeded require more detailed research focused on the sources, paths of propagation, chemical composition and morphology of ultrafine aerosol (UFA). In order to comply with these objectives measurements were carried out directly in production halls and the vicinity of industrial technologies with expected high UFA emission. In line with global trends, focus is increasingly placed on solid aerosols with particle sizes below 1 µm and, where appropriate, on nanoparticles. This is mainly due to a much greater penetration of these particles into an organism and a subsequent initiation of some serious diseases.
