Abstract

Settled dust or suspended particles of dust in air contains transition and post-transition metal oxides like Chromium oxide {Cr2O3}, Manganese oxide {MnO}, Nickel oxide {NiO}, Copper oxide {CuO}, Zinc oxide {ZnO}, Titanium oxide {TiO2}, Iron oxide {Fe2O3}, Zirconium oxide {ZrO2}, Lead oxide {PbO} and Aluminum oxide {Al2O3} and the study was carried out to find out the composition of these metallic oxides and the comparison between them with X-Ray Fluorescence Spectrometer (Chemical Analysis Instrument) by making solid beads of settled dust. Their average percent composition is found as 0.043, 0.0109, 0.013, 0.049, 0.425, 0.485, 5.39, 0.365, 0.031, and 5.55 respectively. Total of four areas were chosen to study within Karachi, a busiest and highly populated city of Pakistan. This study provides helpful data for future research and assignments as the studied metal oxides are the dynamics for environment pollution.

Key words: Settled dust, X-ray fluorescence spectrometer, environment, earth sciences.
