Four dust samples (particulate matter 2.5) were collected from air filters situated in the cities of an agglomeration in a province in Poland and 4 dust samples from various emission sources (coal furnace, car engine, urban agglomeration air and charcoal bag). The content of various crystalline carbon black structure was detd. by Raman spectroscopy and hence the main sources of particulate emission present in urban agglomerations were estd.
