Morphology and Composition of Particulate Matter in the Air of Urban Area

Popis výsledku v původním jazyce

Atmospheric pollution by particulate matter has become increasingly important in recent years, because it was found that these airborne particles have various adverse effects on the environment and human health. To extend the knowledge of such pollutants, detailed characterization of sizes, morphology and chemical composition of individual airborne particles is desired. In the presented research, the air microparticles were taken from discarded fiberglass tape filters which are commonly used in MP101M continuous suspended particulate analysers to determine the mass concentration of the particulate matter. These samples, which were collected in Kutna Hora (Czech Republic), were studied using the methods of scanning electron microscopy and energy-dispersive X-ray spectroscopy. Based on microscopic photographs, various geometrical parameters (Feret’s diameter, perimeter, cross-section surface area, circularity, aspect ratio, roundness and solidity) of 237 particles were assessed, while the spectroscopy measurements revealed elemental composition of these particles. Statistical evaluation of the measured data was done using the methods of principal component analysis and compositional data analysis. By these methods, certain relationships among the geometrical parameters and the content of chemical elements in the particles were found. This research also demonstrated that the fiberglass air filters can easily be reused to gain additional information about airborne particles in various places at any time. The character of the particles can also provide information about a possible source of contamination.
