Abstract :

Air Pollution monitoring studies are one of the most important concern in this present environmental conditions of the atmosphere. Due to the industrialization, vehicular growing, urbanization day by day the air pollution levels are increasing rapidly. Today the air quality is quite different in urban areas and cities then compared too few years back of the natural air quality. USEPA has identified 188 compounds are hazardous depending upon its chemical and physical characteristics. These compounds are called as Hazardous Air Pollutants (HAPs). Out of these 188 compounds 33 compounds are most commonly found in urban areas. These pollutants will be generated from Industrial sources, vehicular emissions, burning of fossil fuels, etc.In this study we made an attempt to study the inorganic hazardous air pollutants like Arsenic, Beryllium, Cadmium, Chromium, Cobalt, Lead, Manganese, Mercury, Nickel and Selenium in Ambient Air Suspended Particulate Matter of in and around the Tirupati area. For this study we were selected five different sampling locations in Tirupati. Sampling was carried out 24 hourly and twice a week for P.M.10 in the month of Feuary 2012. These samples were digested and subjected to analysis for As, Be, Cd, Cr, Co, Ni, Mn, Pb, Se and Hg using Inductively Coupled Plasma -Mass Spectrometer (ICP-MS) based on USEPA Compendium method IO 3.5.The concentration levels of this inorganic hazardous air pollutant are summarized in Table-3 and Table-4.
