Description :
In this paper we present the study of dust particulates collected from six different location in the areas surrounding cement factory in central India and Thermal Power Plant. It is analyzed by Mössbauer spectroscopy that the iron exists in the chemical state of structural iron (Fe2+, Fe3+).The analysis of the 57Fe Mӧssbauer Spectra recorded at room and liquid nitrogen temperatures, showed that iron species in all samples consisted of Fe2O3, Fe3O4, Fe2(SO4)3 and Fe2+ high spin state but their proportions were different in different sites, dependent of each environmental condition. Mӧssbauer spectra recorded at both 300K and 78 K show the differences in the phase composition of iron containing ambient air dust particulates from cement factory. In addition, the transformation of iron compound in air was discussed.
