Aerosol samples were collected in an industrialized region of Bombay. These were analyzed for twenty seven chemical species using inductively coupled plasma emission spectroscopy, energy dispersive x‐ray fluorescence spectroscopy and UV/VIS spectrophotometry. Factor analysis applied on nineteen marker elements extracted seven factors indicating seven major source types contributing to aerosol mass at the sampling sites. Multiple regression taking absolute factor scores as predictors was employed for source apportionment. Finally, source profiles were calculated as percentage of the aerosol mass and compared with the values reported in the literature.
