Airborne particulate matter is considered to be most challenging environmental issues in the world today due to its impact on various atmospheric processes like regional and global climate change, ecosystem, agriculture and most importantly on human health in recent times. Analysis reveals that particulate matter contains various inorganic and organic compounds and biological entities and their secretions and toxic trace metals. The main regions affected are urban centers due to an increasing population, number of diverse industries, fossil fuel driven vehicles and various construction activities. The present chapter deals with the scenario of particulate matter, their sources of generation, size and their impact on human health and environment mainly in urban dwellings.
