The atmosphere is often loaded with dust particles due to various activities such as wind, exhaust from industries, vehicular emission, uplift of Earth surface sediments on the move of vehicles, etc. The dust sediments in the atmosphere contain various minerals. Among the various minerals some of them impose hazardous health effects to human beings. Each and every one on the Earth surface is continuously subjected to the atmospheric dust particles inhaled and sometimes ingested through water and food. The main objective of this study is to characterize the atmospheric dust particles of Cheyyar town, near Kancheepuram, Tamilnadu, India, for their mineral contents using Fourier Transformed Infrared Spectroscopic technique (FTIR). Totally 10 dust sediments were collected around Cheyyar town and analysed for their mineral composition through FTIR technique. Using FTIR spectra it is observed that the air suspended dust particles collected in and around Cheyyar town contain the minerals like Kaolinite, Calcite, Asbestos, Hematite, Orthoclase Feldspar and Montmorillonite. Among the identified minerals few of the minerals like Asbestos may bring adverse and harmful effects to the mankind.
