Abstract– Air is one of the most important elements for the sustenance of life on this planet. But due to various anthropogenic activities air is being degraded drastically and very alarmingly. Air dust Particles size and their compositions are related to be significant factors in the assessments of the acute and chronic impacts of particulate matters on health. Studies examine the elements of particulate matters that exhibit serious health hazards on human health on long exposure and inhalation of these particulates. As a result, there is still a lot to learn about the sources of particulate matters, SO2 & NO2 that may regulate the concentration of these pollutants. Here, we assessed the primary pollutants releasing from the various sources in Ranchi and from the field data of four sampling stations, primary and secondary sources of oxidative potential and particulate matters in Ranchi. We found that the concentration of particulate matters, SO2 & NO2 were mainly governed by secondary aerosols, Auto-mobile emissions, building materials used in construction of roads, highways, and buildings. In contrast, most anthropogenic sources that contributed to the concentration of oxidative potential are fine-mode secondary organic aerosols, which were mostly produced by household biomass burning, and coarse-mode metals, and automotive non-exhaust emissions.
Key words: Anthropogenic, Exposure, Inhalation, Oxidative potential, Emissions.
