Abstract
The results obtained from an investigation of solid aerosols in the Industrial city of Faisalabad (Pakistan) are reported and analysed in this paper. X-ray diffraction studies of the various solid aerosols zones (residential, industrial / traffic and commercial zones) showed that non-clay minerals such as quartz, calcite and albite are contained in most of the samples in almost comparable amounts. Chemical analysis of some samples was carried out for complementing the X-ray diffraction data. The amount of quartz in the samples of industrial zones/ traffic zones was found to be IN an order of magnitude more than in the samples of relatively residential zones. As the dust particles of these compounds are poor substrate for promoting nucleation of ice in the atmosp heric clouds, they are liable to stay steadily in the atmosphere as pollutant. The results of Solid aerosols collected from various sites show that the sources of quartz, calcite and albite in the Solid aerosols are both local and remote.
