Particulate matter (PM) has been considered as one of the most dangerous elements of air pollution. Multiply analytical methods are employed to identify the composition of particles present in the air. The theoretical part of this work is a description of different research centres all over the world where particulate matter is being analyzed using various techniques. The purpose of this project is to analyze and compare particles called PM 10 (particles of 10 micrometers or less) present in the air in different cities. In order to determine the composition and size of particles a scanning electron microscope (SEM) and transmission electron microscope (TEM) equipped with EDX analyzer were used. The TEM analysis gave similar results with additional information of the presence of magnesium and iron in the samples. Finally size distribution was obtained. Size ratio of most of the particles vary from 1,5 to 2. Comparison of size measurements using TEM and SEM techniques showed small differences caused by various sizing methods and different accuracy of microscopes. This work was supported by Ministry of Higher Education and Science grant no. NN305 366338
