AIR POLLUTION ITS EFFECTS AND SOLUTIONS; Dust From Untarred/Unpaved Roads Major Causes Of Air Pollution. Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Road dust is a major cause of air pollution, releasing various types of particulate matter and pollutants into the air, which can result in respiratory and cardiovascular issues. The World Health Organization (WHO) estimates that outdoor air pollution is responsible for around 4.2 million premature deaths worldwide each year, and road dust is a significant contributor to this problem. The composition of road dust varies depending on local factors, including climate, geography, and traffic patterns. However, common components of road dust include soil, mineral dust, brake and tire wear, and other debris. These particles can range in size from less than 2.5 micrometres(PM2.5) to less than 10 micrometres
