The present project is aimed at assessing the negative health impact on workers in terms of inhalation of solid and liquid aerosols which prevail at Faculty of Materials Science in Trnava workplaces. Sampling will be secured by cascading provided filter materials with varying porosity, where each level of cascade is assigned to the one of the human respiratory system. After the collection of the real samples on the workplace (by workers of UIBE) they will be analyzed in the terms of elemental composition (workers UVPT) by method PIXE (Particle Induced X-ray Emission). From the measured data will set the negative impact on workers and proposed solutions to eliminate these impacts.
