The present study aims to measure the concentration of various pollutants present in the ambient air. The primary focus of the study was on Respirable Suspended Particulate Matter (PM10) and Suspended Particulate Matter (SPM) although it also deals with other pollutants like SO2 and Nox. High volume Respirable dust sampler (RDS machine) with Thermo electrically cooled gaseous sampling attachment is used for sample collection. Ambient air monitoring is done at three different sites in Latur city comprising Residential, Commercial and Industrial areas. RDS machine was operated continuously for 48 hours at each site in a weak covering a period of six month. Result of investigation indicates that concentration of RSPM and SPM are exceeding the National Ambient Air Quality Standard at residential and commercial area whereas the concentration of SO2, NOX is bellowing the prescribed limits. Increasing vehicular activities are more responsible for the emission of Particulate matter (PM10). The measure causes includes inadequate improper traffic management system, road condition, absence of effective mass rapid transport system.
